It’s our job to make sure you understand the 4 C’s so that we can find the perfect stone just for you. An Overview of the 4 C’s
Size is the most visible factor that determines the value of all diamonds. The price of the diamond rises exponentially as they get bigger. Despite popular belief, carat is a measure of weight, and not size per se. As the weight increases, so does its size invariably. Just to give you some idea, 1 carat is equal to 200 milligram. Since most diamonds sold in the market weigh less than 1 carat, the carat is usually subdivided into “points”. There are 100 points in a single carat. So, a diamond weighing 3/4 carat would be a “75 point diamond”. This continues as the weight goes over a carat (Example 1 and a half carat = 1.50ct) 1 carat = 200 milligrams = 100 points. A 2 carat diamond would sell for considerably more then a 1 carat diamond of the same colour, clarity and cut. Large diamonds are rarer to find in mines than small ones and thus large diamond tend to be more valuable. It follows that weight and size are extremely important when choosing the perfect stone for your engagement ring.
An ideal diamond is completely colourless. These are considered the most expensive diamonds. Although most diamonds appear colourless, they actually have slight tones of yellow or brown. The Gemological Institute of America (GIA), an authority on diamond certification, grades colour alphabetically from D (totally colourless) to Z (heavily tinted). The difference in grades is very subtle, and mostly not visible to the naked eye. A diamond with a visible tint such as K and above can still be beautiful if it has a good clarity and cut. Only diamonds graded N onwards have a tint that is visible to the naked eye. In terms of colourless range, they range from Top White – Yellow D E F – Top White G H – White I J – Near White K L M – Faint Yellow N and lower – Yellow Different colours set better in different metals, whether it be rose gold, yellow gold, white gold or platinum, our designers will ensure that you choose the perfect colour for your design.
Clarity Ranges from IF (Internally Flawless) – I3 (Highly Included). As diamonds go down the scale (and are more included) it affects their quality and therefore their price. Diamonds with less imperfections or inclusions are more valuable then those with more imperfections or inclusions. FL – Completely Flawless. IF (Internally Flawless) – The external flaws can be removed by further polishing. VVS1 – VVS2 (Very Very Slightly Included) – Only an expert can detect flaws with a 10X microscope. By definition, if an expert can see a flaw from the top of the diamond, it is a VVS2. If the expert can only detect flaws while viewing the bottom of the stone, then it is a VVS1. VVS1 clarity diamonds do not have any internal black marks. Then they also fall in the “No Dosham” or “No Black” category. VS1 – VS2 (Very Slightly Included) – Flaws are visible with a 10X microscope, but it is not obvious (takes more than 10 seconds to identify the flaws). SI1 – SI2 (Slightly Included) – Flaws are readily visible with a 10X microscope. I1 – I3 (Included) – Flaws are eminently visible and can be found with the naked eye. At Shiny Rock Polished we guide our clients through this process very carefully. We tend to avoid (unless specifically requested) diamonds below SI1/SI2. Even then, we ensure that these stones are eye clean (inclusions are not visible to the naked eye).
The cut refers to the proportions, finish, symmetry and polish of the diamonds. These factors determine the intensity and brilliance of a diamond. A well-cut diamond is proportioned, symmetrical, and polished; these are typically the most expensive diamonds. Well-cut diamonds sell at a premium and poorly cut diamonds tend to be priced lower. The width and depth of the cut can have an effect on how light travels within the diamond and how it exits in the form of brilliance. Too much shadow and light is lost from the bottom, causing the diamond to lose brilliance. Too deep a cut allows light to escape from the sides causing the diamond to appear dark and dull. The term “cut” can also refer to the style of the diamond cut, for instance, certain diamond types are known or med after th8eir appearance, like the “cushion cut diamonds,” “round cut diamonds,” “pear-cut diamond” or “heart cut diamonds.”. Round Brilliant, or “round cut diamonds” are the most popular, and remain the most expensive shapes. The fancy shaped diamonds, as mentioned above, are better priced. As you can imagine, choosing the correct shape is vital when deciding on a particular design.
