The Four C’s
The Four C’s
A diamond is one of the largest purchases most people make in their life time. As with any large purchase you should understand what you are buying and take the time to educate yourself as to what to look when shopping for a diamond.
The value of a diamond depends on certain characteristics of the diamond that are graded. Diamonds are examined and graded by trained workers at laboratories using grading criteria established by The Gemological Institute of America (GIA). Four of these criteria are essential to understand when buying a diamond. When you apply these four criteria accurately and completely, you can be confident that you are getting the best diamond quality and value for your money.
Keep in mind that the Four C’s should only be applied to a loose diamond and not to a diamond mounted on a ring. Known as the Four C’s,” these criteria are: Color, Clarity, Carat and Cut.
With an understanding of the Four C’s, you will be able to comparison shop and buy the best diamond at a fair price. But buying a diamond shouldn’t be done on a whim or rushed. Give yourself plenty of time and shop around, see what is out there to be purchased, then decide on the shapes and styles that appeals to you.
Save Money When Buying The Diamond
What Diamond Qualities Worth Paying For
The Four C’s
You don’t have to pay a premium to get a quality diamond:
Cut
A diamonds graded very good (VG) is your best choices for quality and value but for the budget conscious you can pick up a good rated diamond.
Color
A diamonds graded G, H and I are near-colorless and look colorless to the naked eye. These are the whitest stones commonly available in the engagement ring market. A diamond rated G and H on the color scale is your best choices for quality and value.
Clarity
A diamond graded SI-1 or above looks flawless to the unaided eye. Even a tiny inclusion visible to the naked eye will bump the diamond to an SI-2 or I-1. A diamond rated SI2 and VS1 on the clarity scale is your best choices for quality and value.
Carat
Instead of buying a diamond that is exactly .50 carat and 1.00 carat weights buy odd carat diamonds such as a .45 carat diamond, a .80 carat diamond or a 1.55 carat diamond. This will save you money because the price of a diamond jumps dramatically when it reaches a true .50 carat or 1.00 carat because that’s how most buyers want their diamonds. And because demand is high for those diamonds, jewelers charge a premium for them. The difference between a .80 carat diamond and a 1.00 carat diamond will not be apparent to the human eye in a side by side comparison. So save money by not doing what most people do and shop for an odd carat diamond.

Diamond Brands and What They Mean
With the breakup of the De Beers diamond monopoly, and the increased competition from other players like Argyle Diamond Mines from Australia, Ekati from Canada and the Russian United Syndicate, you will be seeing more and more marketing from De Beers and the other syndicates to convince the diamond buyers that their diamonds are better than their competitors’ diamonds.
Diamonds are one of the few products that simply cannot be branded. Even though there are different cuts, different grades, and different values placed on each and every diamond in existence no diamond can really be claimed as any specific brand – with the exception of man-made diamonds. A diamond is a diamond no matter where on earth it is found, who found it or how it found – brands mean absolutely nothing at all. A Canadian diamond is the same as an Australian diamond or an African diamond.
If a jeweler tries to convince you into paying more for a diamond because it is a specific brand, move on to another jeweler. Every diamond syndicate will be selling great diamonds, good diamonds and not so good diamonds. Don’t let the new marketing onslaught that is to come convince you otherwise.
No matter what company’s label is put on the diamond, every diamond buyer will benefit from learning the basics of the four c’s and be able to recognize the quality of the diamond they might consider buying.
Diamond Certificates
Diamond Report
A diamond certification is also known as a diamond grade report. The report, or certification, is like a fingerprint for a particular diamond. The diamond certification is the written documentation of a diamond’s various attributes and dimensions. With it, you know the exact grading for each of a diamond’s
Four Cs – cut, color, clarity and carat
Many diamonds may look the same to the untrained eye. A diamond certificate is an independent verification of the cut, color, clarity and carat of the diamond. The diamond’s flaws (or inclusions) are also noted and, depending on the laboratory grading the diamond, can be plotted on a diagram of the diamond.
With a diamond certificate, you don’t have to worry about a diamond retailer or jeweler telling you anything less than the truth, because the certificate comes from an independent gemological laboratory – not the retailer or jeweler. You may be required to pay for the certificate, but the cost is usually low compared to the cost of the diamond, and in most cases, it will keep you from overpaying for a lower quality diamond altogether or it can help you get the best price on the diamond.
When you buy a diamond, be sure to question the jeweler first about the characteristics or attributes of the particular diamond. Then ask to see the diamond certification that will come with diamond when you buy it. If the particular diamond you are interested in buying does not already have a certificate with it, get one to confirm the diamond’s characteristics or attributes. Don’t buy an expensive diamond without paying the extra cost of the certificate.
If a dealer tries to convince you to make the purchase without the certificate, you should be concerned that perhaps the jeweler may have exaggerated the quality of the diamond and inflated the price.
There are a few different gemological laboratories grading diamonds. Some of the better known labs are: GIA (Gemological Institute of America), AGS (American Gemological Society), PGS (Professional Gem Sciences), EGL (European Gemological Institute) and the IGI (International Gemological Institute).
The two most respected are GIA and AGS. They are known in the industry for having the authenticity and reliability of their grade report. The still relatively small PGS is also a respected name in the diamond industry. Some in the industry feels that EGL and IGI tend to over-grade the diamonds that are sent to them for certification, as well as having less critical grading standards and training criteria for their gemologists. Given a choice of GIA and AGS or EGL and IGI, go with GIA or AGS or even PGS. You cannot go wrong if you look for these names on the grading report before you buy.
A copy of the diamond certificate should be given to your insurance company when you insure the diamond or ring (the diamond and its setting). Keep in mind that a diamond certificate documents a diamond’s quality and does not state the value of the diamond. For an impartial evaluation or estimate of the diamond’s value, you will need to have the diamond or diamond ring appraised by a professional appraiser.
An appraisal is a document used to value the diamond for insurance policies and replacement of the diamond. The appraisal is isuued by an independent appraiser that states the approximate retail value of the diamond based on its cut, color, clarity and carat and the current diamond market prices. If the appraisal is for a set or mounted diamond, the weight of the precious metal, the labor, and the craftsmanship is also included in the appraisal. The more information on the appraisal, the better the chance you will receive an equal replacement value from your insurance company in the event the ring is stolen, lost or damaged in the future. The certificate leaves the insurance company less room to argue the quality and ultimately the replacement value of the diamond or ring.
A diamond certificate will also be useful when you later decide to sell the diamond because the potential buyer, like you when you were shopping for a diamond, will likely ask to see the certificate. If you do not have one, you will have a hard time selling the diamond to someone else.
With a diamond certificate, you don’t have to rely sorely on the honesty of the jeweler when buying a diamond. You may pay a little more money for the certification, but the cost is well worth the peace of mind you get from knowing that you didn’t overpay for a lower quality diamond.
Cut
Cut – One of the Four Cs
Cut is probably the most important of the four c’s and is the only one of the four c’s that is controlled by a human being.
The cut of a diamond refers to the angles and proportions (height, width, depth) of each diamond. As one of the four C’s, cut does not refer to the shape of the diamond: round, princess, radiant, oval, emerald, heart, marquise, pear, cushion, asscher, baguette and trillion. Cut dictates a diamond’s reflective quality. Most diamonds are cut with 58 facets. The different angles and the finish of a diamond determine its ability to reflect light and give it its brilliance and scintillation by allowing the maximum amount of light that enters through its top to be reflected and dispersed back, also through its top, into the viewer’s eye.
When a diamond is cut too shallow or too deep, the light that enters through the top is allowed to leak out through the bottom and does not reflect back, making the diamond look less brilliant and firry.
A poorly cut diamond is significantly cheaper than a well proportioned one. Many cutters choose to sacrifice some of the diamond’s beauty to achieve a stone that is a larger carat weight. Some jewelers will downplay a diamond’s bad cut and try to convince you that the diamond is larger. But keep in mind that just because two diamonds have the same weight, does not mean they are the same size.
The cut of a diamond can also affect its durability as well as its beauty. Some cutting faults can make a diamond prone to breakage when it is set or mounted on an engagement ring.
Choosing a diamond’s cut quality is difficult for a lay person. That is why you should always get a certification from GIA, or any of the respected labs, to verify a diamond’s quality.
A diamond’s certificate will list the important proportions of that diamond:
Table percentage (table / diamond width)
Depth percentage (depth / diamond width)
Cut quality is difficult for a lay person. That is why you should always get a certification from GIA, or any of the other respected labs, to verify a diamond’s quality.
Just compare these numbers against a master chart of percentages for that diamond’s shape. A master chart will tell you what the ideal proportions are for particular diamond shape.
The certificate will also list the polish and symmetry of a diamond.
Polish will indicate any nicks, scratches or other flaws on the surface of the diamond.
Symmetry will indicate the accuracy of the cut to the shape and pattern of the facets.
The GIA rates both as EX (excellent), VG (very good), G (good), F (fair) or P (poor). The AGS rates both as ID (ideal), EX (excellent), VG (very good), G (good), F (fair) or P (poor).
A diamond graded very good is your best choice for quality and value. But if you are on a tight budget go for a good rated diamond.
