Judging Diamond Quality

What to Look For

If you want to begin judging diamond quality, you must first learn and understand the 4 C’s, which are four characteristics of diamonds that give the gem stone it’s overall value. The 4 C’s for judging diamond quality include the diamonds color, clarity, carats and cut.

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. The colors of diamonds are rated with an alphabet grading system that starts with “D” and ends with “Z”. Completely colorless diamonds fall in the “D” and “E” grade, while colored, fancy diamonds are at the other end of the alphabet, at “Y” and “Z”.

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.

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.

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.

Jewelry Lab Certificates and Appraisals

The Difference Between Jewelry Lab Certificates and Appraisals

Most people have both jewelry lab certificates and appraisals for their valuable jewelry, but the two documents are not one in the same. They serve different purposes and contain a different set of information that is helpful to jewelry owners, as well as to people who are looking for new jewelry to purchase.

Jewelry lab certificates and appraisals often go hand in hand, but the lab certificate is a document that describes information about an unmounted gem stone, like a diamond that has not been set into any piece of jewelry, while the appraisal provides detailed information on the market value of a piece of jewelry, whether it is unmounted or already set as a ring, earrings, or necklace for example.

Choosing Labs and Appraisals

When selecting jewelry lab certificates and appraisals on jewelry that you are considering to purchase, it is best to select an independent company that provides these documents rather than rely on the documents created by the company that you are planning to buy your jewelry from. Otherwise, you face the potential for the lab or appraiser to be biased, since they will benefit from the sale of jewelry.

If you already have jewelry lab certificates and appraisals on your existing jewelry, but are unsure of their accuracy, it may be worthwhile to have your items appraised again to see what their current market value is.

Jewelry Lab Certificates

Jewelry lab certificates are written reports that detail unmounted gemstones rather than completed pieces of jewelry. The certificates include information about the diamonds (or other gemstone) cut and shape, as well as the stone's color and clarity grades as decided by the Gemological Institute of America (GIA). Lab certificates contain specifics about the carat weight as well as the dimensions of the diamond, taking into account the stone's angles.

Once the lab certificate is drawn up, it should not change unless the stone is physically altered or it is found at a later date that the gem stone was evaluated incorrectly the first time.

Jewelry Appraisals

The entire reason people obtain jewelry lab certificates and appraisals is to document the dollar value of the diamond, whether it is for personal investment purposes, or in order to have a physical record of the gem stone for insurance purposes. It is also great documentation to have if you ever decide to sell your jewelry at a future date, or pass it down to family members.

It is wise to have your existing valuable jewelry appraised in case it is stolen, or in the event you go through a divorce or estate settlement. Before purchasing a new piece of jewelry you can also get it appraised to get a good idea what the market value is on the piece before shelling out large amounts of money to pay for it if it isn't worth the amount of money they are asking for the piece.

Diamond History

Diamond history varies greatly depending on your source of documentation, as diamond history is as rich in myths and folklore as it is in physical facts and records. Diamond history is one filled with mythical stories, such as one where snakes guarded a land full of diamonds, and the history has fascinated people with the romance and beauty that surrounds our most precious gemstones; diamonds.

Early Diamond History

Around 3,000 years ago, in the country of India, the first ever diamond history was recorded. If diamonds had been found prior to this period of time, we have no written record of it Diamonds in this day and age were used for two main purposes, and is quite different from why we still love diamonds today. Diamonds stood as a talisman in order to fend off evil spirits, and to provide protection during battles, and they were also valued because of their ability to reflect the light.

Dark Ages of Diamond History

It is during the dark ages that the diamond history moved into having some sort of medical purpose. St Hildegarde was said to have written an anecdote to heal wounds and cure illnesses that instructed the sick to hold a diamond in their hand and make the sign of the cross. Some people in diamond history went as far as swallowing diamonds, hoping it would cure their illnesses magically.

Middle Ages of Diamond History

It was during the middle ages that diamonds began to gain popularity. It is this point in diamond history that many of the famous diamonds were discovered, including the Blue Hope, and the mountain of light, both found in India. In our current times, India remains the worlds finest polishers of diamonds.

The middle ages also saw a shift in diamond history- where previously diamonds were valued based on their mythical powers, they began to be valued more for their overall worth. As more people learned of the incredible value of diamonds, mine owners began circulating stories that diamonds were poisonous, to prevent the workers from swallowing diamonds as a means to smuggle them out of the mines undetected.

Also during this period of diamond history, people wanted diamonds more than any other time period previously, mostly because they recognized their power and worth. India's diamond supply was dwindling and was unable to meet demands of diamond buyers. South Africa's find of diamonds near the Orange River began the world's largest diamond rush of diamond history, and helped satisfy the demands of those wanting diamonds for themselves.

Diamond history began to spread into eastern Australia sometime during the middle of the nineteenth century. During the late 1970's, Australia as a diamond producer became validated. Also in the late 1970's, 1979 to be exact, the Argyle pipe near Lake Argyle was discovered by geologists. Since that day, Argyle has become the absolute largest producer of diamonds in all the world and throughout diamond history, and produces over one third of the diamond volume each year.

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.

The Value of the Diamond is Effected by it's Weight.

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.

Selecting Diamond Carat

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.
