This is a sponsored conversation written by me on behalf of Shane Co. The opinions and text are all mine.
Guys, I’m sure you were like me when it came to purchasing your soon-to-be-wife’s engagement ring that you didn’t have a clue what you were getting into. Being that I’m a penny pincher or just someone that want to know everything about a product before I invest in it and believe me, engagement rings and wedding rings are huge investments. Here are some things I learned from snooping around the Shane Co. website and this is something you guys will hopefully find it helpful. One of the things to know when looking for that perfect ring for that perfect person is the 4 Cs, which are Carat, Clarity, Color and Cut.
Diamonds are sold by the carat (ct), which is a unit of weight, not size. One carat weighs 200 milligrams, or one-fifth (.2) of a gram. This standard has been in use worldwide since 1914, when it was proposed by the International Committee on Weights and Measures. Now remember that carat is a measurement for precious gems and karat refers to gold quality in the United States. When discussing gemstones of less than one carat, jewelers often refer to the weight in terms of points. A carat is divided into 100 points, with one point corresponding to .01 carat. Think in terms of pennies to a dollar. Very small gemstones, such as those used in pavé or channel settings, are sometimes called melee. Melees range from .01 to .16 carat in weight. Although the analogy of pennies to the dollar suggests that one carat is always 100 points or that one-half carat is always 50 points, that’s not entirely true. Diamonds can’t all be uniformly cut to such exact weights, so the carat weight given is an approximation of the actual weight of the gemstone. Since diamonds become rarer as they increase in weight, the larger the diamond, the more valuable (and costly) it is. But the price of a diamond does not increase at the same rate as its weight. The larger the gemstone (all else being equal), the more disproportionate the increase in cost per carat. When evaluating diamonds, weight and size is not the same thing. Yet, carat weight has come to represent particular sizes when based on a well-cut diamond. Since ancient times, diamond cutters have sought to produce a diamond of maximum possible weight and quality from the rough crystal. Similarly, while your first inclination may be “bigger is better,” that’s not necessarily true for everyone, as quality and budget need to be considered.
The “C” of clarity refers to a gemstone’s purity. Clarity is evaluated by viewing the gemstone under 10X magnification. Virtually all diamonds contain tiny natural birthmarks that are present to varying degrees. After all, nature is rarely perfect, and that extends to diamonds! These marks serve as the identifying “fingerprint” that makes every gemstone unique. These tiny identifying marks consist of “naturals” on the outside or inclusions on the inside of the gemstone. Inclusions refer to anything that is trapped within the diamond crystal. Nearly all diamonds, even those of the highest quality, have some inclusions, which fall into these categories:
Mineral inclusions: A dark spot from a trapped bit of mineral.
Naturals: Open cavities interrupting the diamond surface that were a part of the original diamond crystal.
Feathers: Internal cracks or fractures caused by either internal or external stress during the diamond’s formation.
While there are several grading systems used in the industry, the most recognized and commonly used system is the one developed by the Gemological Institute of America (GIA).
FL- Flawless. Shows no inclusions or blemishes of any sort under 10X magnification when examined by an experienced grader. Extremely rare.
IF- Internally Flawless. Have no inclusions when examined by an experienced grader using 10X magnification. Very rare.
VVS1, VVS2- Very, Very Slightly Included. Contains minute inclusions that are difficult even for experienced graders to see under 10X magnification.
VS1, VS2- Very Slightly Included. Contains minor inclusions ranging from difficult to somewhat easy to see for an experienced grader when examined under 10X magnification.
SI1, SI2- Slightly Included. Contains inclusions that are easy to very easy to see for an experienced grader under 10X magnification. Some inclusions may be visible to the unaided eye.
I1- Included. Contains obvious inclusions visible to an experienced grader under 10X magnification; can be visible without magnification.
I2, I3- Included. Contains obvious inclusions. Visible without magnification.
Of the 4 Cs criteria, the quality of color refers to a diamond’s body color, not the rainbow surface of reflected light. When buying a diamond, it is the absence of color that makes one diamond more precious than another. The whiter or more colorless the gemstone, the more rare, and the higher the price!! The exception is “fancy” colored diamonds, which can occur in shades of blue, pink, red, yellow, green and brown. Some of these are exceptionally rare and considered collector’s items. Most diamonds that are mined have a great deal of body color while very few are completely absent of color. For a mental picture of “colorless” or the “absence of color,” just think of pure water. Color is graded by the Gemological Institute of America (GIA) with letters ranging from D (completely colorless) to Z (light yellow).
GIA Color Rankings
D, E, F- Colorless
G, H, I, J- Near Colorless
K, L, M- Faint Yellow
N, O, P, Q, R- Very Light Yellow
S, T, U, V, W, X, Y, Z- Light Yellow
Color is actually one of the most difficult factors to evaluate. For one thing, everyone sees color differently. Differences in color between gemstones are very, very subtle, and may be imperceptible to an untrained eye. In fact, even the experts will compare an ungraded gemstone to one previously graded to properly assess its color. Small differences in color can make large differences in the price. A diamond may exhibit the color of its setting, which is why most ring settings will have a white gold or platinum head. White gold and platinum have the least effect on the diamond’s color. Conversely, a diamond with more body color is often best enhanced by a yellow gold setting. Of course, the setting you choose is a matter of personal preference. Some diamonds naturally exhibit a bluish tint when viewed in daylight or under fluorescent lighting. Under candlelight or normal incandescent lights, the blue disappears. This blue tint is the result of the gemstone’s degree of fluorescence. It is not considered either good or bad, but simply an inherent characteristic of the gemstone.
The cut is extraordinarily important because it has the greatest single influence on the diamond’s brilliance, or sparkle. And when it comes to diamonds, sparkle is what makes diamonds “a girl’s best friend.” Occasionally you may find other jewelers’ gemstones are priced lower than Shane Co. diamonds of identical carat weight, color and clarity. That’s because the diamonds at the other jewelers are cut too shallow or too deep – causing the light that enters them from above to leak out of the bottom and sides of the gemstone. As a result, these gemstones are visibly dull and dark and consequently, highly undesirable. Remember: it takes all 4 Cs to complete the picture and determine a diamond’s value. So pay special attention to cut when evaluating diamonds and believe your eyes. Judging a diamond’s sparkle by its lab grade alone is like judging a movie solely by its rating. A laboratory grade is only part of the story, because diamonds with the same grade can have very different amounts of sparkle, depending on how each diamond is cut and where the inclusions are located inside the diamond. When Shane Co. buys diamonds, our own buyers go directly to the diamond cutters around the world and examine groups of diamonds already sorted by grade. Then they handpick only the diamonds with the most sparkle from within each grade. Whatever diamond grade you choose, you will clearly see the difference in the way Shane Co. diamonds sparkle. Cut specifically addresses the number, placement, angling and shape of the facets to create a polished diamond. The facets function as prisms, capturing and reflecting light inside the diamond. The quality of a gemstone’s cut is primarily determined by the height of the crown relative to the depth of the pavilion and the width of the table.
Crown- The part of the diamond above the girdle
Table- The large facet that caps the crown of a gemstone
Girdle- The outer edge of the diamond, usually the portion that is grasped by the setting. It is the dividing line between the crown and the pavilion.
Pavilion- The part of the diamond below the girdle.
Culet- The small facet parallel to the girdle, at the bottom of the gemstone.
Of the four qualities that define a diamond’s value, the cut is the only one determined by a human being. A skilled diamond cutter realizes the rough diamond’s potential. He cuts and facets the crystal to reflect the maximum amount of light inside the gemstone and back through the top of the diamond. His objective is to produce a perfectly symmetrical gemstone that’s right and left sides are mirror images of each other. At the same time, he has to find the optimal balance between yielding the most diamond weight and creating the best proportioned cut. One reason why higher grades of cut are so much more costly is because more diamond was sacrificed to create them. That’s also why a well-proportioned one-carat diamond may be worth twice as much as a poorly proportioned larger diamond that lacks fire and brilliance.
For centuries, diamond cutting experts have pondered what combination of proportions creates the optimal balance of brilliance, scintillation and dispersion (the diamond’s sparkle and fire). The 58-facet model developed in 1919 by master gem cutter and mathematician Marcel Tolkowsky has provided a foundation for today’s most widely accepted proportions. However, while Tolkowsky’s model dictated precise proportions for table diameter, crown height, pavilion depth, crown angle and pavilion angle, many grading labs and diamond sellers today offer a more liberal interpretation. The market itself dictates a wider range of acceptable proportions. In fact, the Gemological Institute of America (GIA), the world’s leading gemological authority, actually advises against using the term “ideal” cut. Why? Because the GIA has demonstrated that literally thousands of variations on these proportions can maximize the different optical characteristics displayed by a diamond. As long as the diamond’s proportions fall within the acceptable range of tolerances (and Shane Co. searches the world’s markets for the finest cuts), you can be assured of buying a gemstone that is well made. Furthermore, you could view two gemstones with vastly different cut proportions, and be hard-pressed to determine which gemstone is more beautiful.
The way a gemstone is cut can affect its appearance in other ways. If the diamond has a deep cut, it actually looks smaller than another diamond of the same weight that is cut well. Likewise, a diamond that has a spread cut (cut shallow) will appear larger than another diamond of the same weight that is cut well. A diamond that is cut either too deep or too spread is typically undesirable. You can visit their website and start designing your own ring or pendant and they discuss the 4 Cs also.
The Kimberly Process
Last but not least, anytime you’re dealing with diamonds there’s always a chance of some companies trying to sell you conflict diamonds and there’s a process that Shane Co. follows to ensure they don’t deal with suppliers that comply with the Kimberly Process. Conflict diamonds, also known as “blood” diamonds, are gemstones sold to finance violent rebel movements. Conflict diamonds have been linked to atrocities in Angola, Sierra Leone and the Democratic Republic of the Congo.
In order to put an end to financing violence, and to set consumers’ minds at ease about funding human rights violations, South African diamond producing states met in Kimberley, South Africa in May of 2000 to devise a solution.
With the support of the United Nations, the diamond industry, world governments and NGOs went to work. Nearly two years of negotiations ultimately produced the Kimberley Process Certification Scheme (KPCS). The scheme outlines strict standards for rough diamond trade to guard against conflict diamond trafficking.
The Kimberley Process is made up of 43 states and regional economic integration organizations. Together, these participants account for approximately 99.8% of the global production of rough diamonds. The process has been very effective and continues to evolve. Annual meetings and open communication between participants are bringing the world increasingly closer to eradicating conflict diamond trading across the globe. Below is the policy regarding the Kimberly Process that they’re always upheld.
We uphold the highest standards of business ethics for ourselves, our vendors and suppliers. We only do business with vendors and suppliers who comply with the Kimberley Process, the Voluntary System of Warranties, and United Nations resolutions pertaining to conflict diamonds. In fact, well before the Kimberley Process was established, Shane Co. issued letters to all its vendors insisting that they be vigilant about not purchasing diamonds from conflict areas. Since 1929 the Shane family has taken the utmost care to do business only with suppliers who possess integrity. Purchasing our gemstones directly from cutters allows us to be extremely selective with our suppliers.
