How to Judge a Diamond's Quality

When begin to search for a perfect diamond, We will certainly find that there is a big difference in price, and price is usually based on assessing the quality of the four Cs of diamonds, including cut, clarity, color, and carat.

Before we make a diamond purchase, we need to familiarize yourself with these terms, and we also need to find a reputable jewelry. Although we can examine the diamond yourself, we can ensure that we get value for the price only if we rely on the expertise of a specialist diamond.

Judging Cut
One of the most important factors in judging diamond quality is judging the cut of a diamond. It’s important because a quality cut diamond will be more brilliant and reflects light more beautifully, and yet the cut of a diamond has the least impact on the overall price of the diamond.

When judging diamond quality on the cut of a diamond, look at the stone in a well lit area. If the light seems to go into the stone and bounce back, showing a sparkling reflective surface, the diamond has a good cut. The angles and shapes of a diamond are important to judging diamond quality and the overall appearance of your diamond.

Not the shape of the stone, cut refers to how well a diamond’s facets are proportioned and aligned to maximize brilliance. According to Tiffany, an excellent diamond cut might sacrifice as much as 62 percent of a stone’s total weight.

Judging Color
Most diamonds are considered to be ideal if they are transparent, or colorless. Diamonds that are rated as colorless are the most expensive of diamonds.

There are two main ways that jewelers’ use when judging diamond quality based on color. They may pull out a set of reference stones, and find the closest match between the diamond and the reference stone to determine its letter grade. Alternatively, the jeweler may use a colorimeter, which can electronically measure the color of the stone and determine its grade within 1/3 of a grade.

When rating the color of a diamond, jewelers commonly use the letters D through Z. The more yellow or brown tint a diamond has, the less value it receives. The rating D represents a diamond that is colorless; while the rating Z has a yellow or light brown hue.

Judging Clarity
The clarity of a diamond refers to whether or not the diamond is clear all the way through, or whether it has tiny flaws and cloudy areas within the gemstone. It’s actually very rare to have a diamond with absolute perfect clarity and no flaws, but most diamond flaws are not visible to the naked eye and can only be seen with a magnifying device.

The Gemological Institute of America (GIA) uses a magnification of about 10x when judging diamond quality based on the clarity. There are treatments available to make a diamond appear nicer than it actually is, and the treatments should lower the overall price of the diamond so it is important to do your research before purchasing a diamond to be sure you are not spending more money than you should.

Judging Carat Weight
Carat is the term we used to describe the weight of a diamond gemstone. One carat is equivalent to 200 milligrams of weight. A single diamond with a high amount of carat weight is more expensive than the equivalent amount of carats in multiple stones. This is because finding the larger diamonds is much more rare of an occurrence.

So if you want a 2-carat diamond ring, for example, you may decide to go with a half-carat diamond surrounded by smaller diamonds that add up to one and a half carats to give you the total of 2 carats! Judging diamond quality by the amount of carats is difficult, since different shaped gemstones, and stones with different levels of clarity will be priced differently even if they have the same amount of carats.

How to Spot A Fake Diamond

For some people, a diamond is a diamond. For others, only a natural diamond is a diamond.

Diamonds are hard to replicate, due to their very particular set of qualities. However, some replicas can be very convincing.

Diamonds can be created in laboratories, and other materials can be used to create gems that resemble diamonds closely, such as cubic zirconia, moissanite, crystal, and rhinestones.

And for some people, even a natural diamond is a “fake” if it has been enhanced. With so many definitions of fake, it is best to break this question down to address each style of “fake” diamond. The only way of making certain a diamond is real is by having it examined by a professional appraiser.

As a buyer, we should be less afraid of “fake diamonds” and more cautious about the seller representing a diamond stone as accurately as possible. When the diamond is accompanied by a third-party certificate, it is more likely to be what the seller claims it to be. All other purchases are less certain.

If you don’t know much about diamonds. There are some steps that you can take to avoid buying a fake diamond.

First, only deal with reputable jewelers, and when you find a reputable jeweler, stick with them. Avoid buying diamonds or other jewelry from jewelers that you have never dealt with before in the past. Ask to see the certificate for the stone. If no certificate exists, walk away.

Look at the setting that the stone is in. Fake diamonds, such as zirconias, are usually set in low quality metals. Take a close look at the stone. Fake diamonds are not durable – natural diamonds, on the other hand, are the most durable stone on the planet. Look for scratches or nicks.

After purchasing a diamond, take it to another jeweler for appraisal. In fact, take it to two or three other jewelers for an appraisal to make sure that the appraisals are all fairly close. If you find that you have purchased a fake diamond, you may be accused of making a switch when you return to the store of your purchase; therefore, it is important to have a certificate for the diamond. No two stones are alike.

Internal Diamond Flaws and Inclusions

When you are looking for a diamond, be sure you find a jeweler whom you trust. A reliable jeweler should be willing and eager to point out various inclusions in each diamond. He should take the time to explain the make-up of that diamond and give you as much detail as possible, letting you look through his magnification tools to see for yourself.

Even with a trustworthy jeweler, however, it is wise to get an independent appraisal from a third party. Some sellers provide this service through a third party at no charge to customers buying a diamond. If not, many jewelers provide independent appraisals on pieces not sold in their store.

Diamonds flaws are common and most diamonds are not perfect and most of them consist of some inclusion or imperfections. These inclusions are also known as flaws and exist in various forms, exterior and interior. Inclusions are also classified in the manner in which they were formed. For example, syngenetic diamond inclusions are those inclusions which were formed while a diamond was being made. On the other hand, epigenetic inclusions were formed after a diamond was made.

Internal Diamond Flaws
When a diamond is considered to have a flaw, it is an imperfect gem stone. Something about the diamond did not form correctly, or there are tiny imperfections within the stone. Diamond flaws and inclusions are often not noticeable to the average person, and you need not worry about the small inclusions that occur in most diamonds. There are actually only very few diamonds which can be labeled “perfect”, and if they are placed in the category of no diamond flaws and inclusions, chances are the diamond will be extremely expensive!

There are some minor inclusions which cause a diamond to appear slightly dull. The inclusion within the diamond can affect the stone's clarity because as light passes through the stone, it is intercepted by the inclusion. Many of these flaws and inclusions can be reduced or fixed with the various forms of treatment processes that gemologists and jewelers have learned to do over the years.

Other diamond flaws and inclusions may be large enough to cause weakness within the gem stone, and the stone could shatter or break much more easily than a stone without the weakness. These are the flaws you want to be careful with, since they reduce the value of your stone.

Pinpoint Inclusions
When a diamond has speckles of dark crystals in groups or scattered throughout the stone, it is said to havea form of diamond flaws and inclusions called pinpoint inclusions. If the dark crystals are all clustered together in the stone, the clarity of the diamond is effected, and it appears to have a “cloud” inside the stone. These types of diamond flaws and inclusions may cause the diamond to be worth less, as it greatly effects the appearance.

Problems from Laser Treatments
When an imperfect diamond is treated with lasers to remove dark diamond flaws and inclusions from within the gemstone, sometimes a line is left through the diamond that looks much like a thread. The laser line begins at the outer edge of the diamond, and moves inward to the area where the dark inclusion was treated by the laser. These diamond flaws and inclusions are unsightly and easily spotted by most people, making the diamond less desirable.

Mineral and Crystal Inclusions
While most diamond flaws and inclusions are negative, there are instances when the diamond flaws and inclusions are actually an eye catching aspect of your diamond! For example, diamonds typically have smaller crystals inside the diamond, often so tiny they cannot be seen without some sort of magnifying device. The clarity of the diamond can be effected by these crystals, if there are enough of them and if they are all grouped together in one area of the diamond.

There are a few rare instances when another gem stone is actually inside a diamond, and could certainly not be seen as a diamond flaw or inclusion. For example, if you had a ruby or emerald that was surrounded by a diamond, you would see that as a special piece of jewelry- not a flawed one!

Evaluating Diamond Color, Diamonds Graded, And Fluorescence of Diamonds

Evaluating Diamond Color

What exactly is diamond color? While most people think of the classic, transparent diamond, which happens to be the most rare and valuable, the colors of diamonds actually range from transparent all the way to a brownish color. There are different saturations of diamond color, and tones.

The Gemological Institute of America, known as the GIA for short, is the most commonly used system for evaluating diamond color. They've created something known as the “GIA Color Grade Scale”, and it has placed a grading system on the many different colors and shades of diamonds, classifying into 22 letter grades.

How Diamonds are Graded
The Gemological Institute of America has certified diamond color grades as “master color comparison” diamonds. When a diamond is being graded, it is compared against these master color comparison grades, to find the shades that match it most closely. The diamond that is being graded must be thoroughly cleaned and all oil must be removed from the surface before being examined, since even small amounts of dirt or oils on the surface of the diamond can alter the color.

A line of master color comparison diamonds or shade chart is set up, with each grade placed about one inch apart, ranging from the lightest and highest graded D shade, to the darkest, graded Z diamonds. The diamond color that is being graded is moved from the left side of the comparison units to the right, until it matches one of the shades.

Diamond grading should take place in a colorless environment, using a balanced fluorescent light source that has a filtered, cool white sun like ray. The room where the grading takes place is dark, all except for the special grading light, in order to obtain the most accurate grading of the diamond color.

Fluorescence of Diamonds
Yet another consideration when considering the diamond color is diamond fluorescence, and how it will effect the actual appearance in the diamond color. Fluorescence causes some diamonds to change color when viewed in our everyday, ultraviolet lighting, as well as under fluorescent light bulbs.

When a diamond color is graded, the strength of the fluorescence of that diamond must also be indicated. It may be considered to be strong, moderate, or weak fluorescence, and the reports must also indicate what color the diamond will change to due to the fluorescence. The reason for this is when people are in the jewelry store, looking at diamonds in the special lighting of the store, they may all appear to be the colorless, transparent diamonds. When you purchase a diamond and get it home under normal lighting, you could find your diamond is yellowish in color!

You can ask your jeweler to provide grading documentation and information about the fluorescent value of a particular diamond before purchasing, to make sure that you will be happy with the diamond you buy. Many jewelers also can show you the diamond under different lighting conditions, which will enable you to fully appreciate the beauty of the diamond before you buy it. Some individuals like a diamond color with a darker shade, while others are insistent on the transparent diamond color. The diamond color is one of personal preference, so be sure to do a little research before making your final selection.

Diamond Carat - What is Diamond Carat Weight?

Diamond Carat - What is Diamond Carat Weight?

When shopping for a diamond, you've no doubt heard references to the 4 C's of diamonds. Diamond carat is one of those popular ”c's” to consider when evaluating a diamond, and it's a term used to describe how much the diamond weighs. A single diamond carat is equal to the weight of 200 milligrams, or .2 grams.

Diamonds are described two different ways in regards to the diamond carat. An abbreviation of “ct” is used to describe the weight of a single diamond stone while an abbreviation of “ct TW” is used when describing the total weight of an entire piece of jewelry- when it has more than one stone in place.

It's important to recognize that two stones may have the exact same carats, meaning they have the same weight measurement, and yet they are completely different in size and appearance. This is due to the actual density of the gemstone. The more dense a stone is, the more weight they have, and sometimes a smaller stone will actually weigh more than a larger stone because of density.

When selecting your diamond ring, you can choose between a single, solitaire style setting (a single diamond on the ring) and a setting that has multiple, smaller stones to make up the ring. The value of a solitaire one diamond carat will actually be more than if you buy a ring that has two diamonds that add up to one carat or greater. Larger sized diamonds are more rarely found when mining diamonds, making them more valuable and expensive than purchasing the same amount of diamond carats in smaller stones.

So how do you determine what size diamond to buy? Do you want a diamond carat of 1, or 2, or do you want a ring with multiple, smaller stones? The answer to this will depend greatly on your budget, as well as the person who will be wearing the ring.

A diamond will look larger on a slender finger, so keep that in mind if the recipient of the ring has thin hands. The actual diamond carat measurement is probably not as much of a concern as the appearance, shape, and setting of the ring. Particularly because a 1 carat diamond ring will not look half the size of a 2 diamond carat ring, it's far more important to select a ring that is pleasing to look at than it is to buy one with the most carats you can afford.

Determine how much money you have to spend, and then decide on the cut of the diamond. Once you have these two pieces of information narrowed down, you can start browsing the diamonds in your price range, in the style you want, and find out what diamond carat you are in the market to buy.

Treated Diamonds - Why Treated Diamonds Exist

Treated Diamonds - Why Treated Diamonds Exist

For centuries, people have always tried to improve objects that are a result of nature. We've cross bred plants and even animals to produce new species, and we prune and shape trees and bushes to make them more pleasing to the eye or to create fancy borders around our yards and in front of our homes. When it comes to diamonds, many become treated diamonds by the jeweler, in order to improve their appearance.

Treated diamonds can have improved clarity, improved color and even be completely coated to improve it's overall appearance. On the positive side, treated diamonds can help people with limited budgets have the ability to purchase a gorgeous looking diamond.

Clarity Improved Diamonds

In order to improve the clarity of diamonds, sometimes tiny cracks in the diamond are filled with molten glass. This can cause the diamond to move up a grade in the GIA grading system, and it does not affect the overall weight of the diamond. The process was invented by Israeli diamond cutter, Zvi Yehuda in 1982. Since this invention, some companies have begun a new process that fills the cracks with bromine instead of the molten glass, however, bromine will sometimes discolor the diamond under certain lighting conditions. It's always best to ask what method the diamond has been treated with when considering treated diamonds, so that you are not surprised when you view the diamond in light outside the jeweler's.

Colored Diamonds

There are a few different types of color treated diamonds. Colored diamonds are actually painted in order to take away a yellowish tinge, and make the diamonds appear more white and transparent. Some are colored darker, in order to permanently alter a diamond to a different color by using electron bombardment. Others become treated diamonds by way of laser drills. In the 1970's people began using lasers to drill miniscule holes into the diamonds to reach dark colored spots. Once they reach the dark colored areas within the diamonds, they are able to bleach them with acid so that they are not as noticeable. Sometimes they finish the laser treated diamonds by then filling the tiny holes with molten glass.

Coated Diamonds

Coated treated diamonds are much like a colored diamond, except for the entire diamond gets a coating of a substance that is designed to make the diamond appear brighter and more translucent to the naked eye. In fact, the coating is so good on most treated diamonds that it can go undetected unless an experienced gemologist studies the diamond for it's value.

Treated diamonds are often very beautiful, and can be more affordable than diamonds that are not treated. If you decide to purchase a treated diamond, just be sure you inform the jeweler when you bring your diamond in for cleaning, as they may need to use different chemicals to clean it and maintain it's treatment.

The Best Diamond Pricing Process

If you have been shopping for diamond jewelry, you have probably noticed that jewelry such as engagement rings, eternity rings, diamond necklaces and earrings are on the market for a wide range of prices. In fact, the difference from one diamond ring to the next can easily be several thousand dollars. For most consumers, price is an important factor in a buying decision, so it is important to understand what you are paying for when you purchase a brilliant piece of diamond jewelry.

Pricing most products is quite easy. Determine how much it costs to make the item, how much it costs to market that item, and then mark it up by 15 – 30% or more. Simple, right? Well, pricing diamonds isn’t quite that simple. There are many factors that are considered when diamonds are priced.

Diamond prices are determined first by adding the cost of the rough diamond, the cost of cutting the diamond, and all other costs necessary to turn the rough diamond into a marketable diamond. Depending on the importance of the diamond, an independent company may be called in to certify the grade of the diamond based on color, cut, clarity, and weight.

At this point, the diamond becomes more expensive each time it changes hands, untilit finally reaches a retailer, where the price is raised a bit more. Before reaching the retailer, however, the diamond must travel from the mine, to the cutter and polisher, to the independent grading company, and then to the Primary market. Once it has reached the primary market, it will be purchased by diamond dealers and wholesalers, and from there it will be sold to retailers.

As you can see, the earlier you can purchase a diamond in the process, the lower the cost of the diamond will be – but not the value. The value is based on what the diamond will sell for in the market place – through a retailer.

If you own a diamond, and you have no idea how much it is worth, you can have it appraised, but the appraisal may not be accurate. You will be better off obtaining a certificate through GIA – Gemological Institute of America. With the information on this certificate, you can use a cutter’s guide to accurately determine what yourdiamond is worth.

There are also many diamond price calculators available. These can be found on the Internet, and many diamond dealers use these as well. You must realize, however, that before you can accurately price a diamond, without a Diamond Grade Report, you need to know quite a bit about diamonds, such as different cuts, clarity, color, and weight – and how each of those aspects adds to the value of a diamond, or decreases the value of the diamond as the case may be.

Again, you will be better off if you get a Diamond Grading Report on the diamond, and use that information to look up the price in one of the guides that the diamond cutting industry uses. This will give you the most accurate value of the diamond in your possession, or of the diamond you are considering purchasing.
