The carat is the standard unit of weight for diamonds and other gemstones. As round diamonds are predominantly cut to specific millimeter sizes our chart below can help to give you an idea of how large certain stones actually are. As diamonds are natural stones and cut differently there can always be slight variations.
Diamond color evaluation is actually based on the absence of color. A chemically pure and structurally perfect diamond has no hue. For many people the color differences are very difficult to notice but these distinctions make a difference in terms of diamond quality, value and price. At the Carbon Culture we only use colorless and near colorless diamonds.
FL (Flawless)No inclusions or visible blemishes under 10x magnification.
IF (Internally Flawless)No inclusions, but barely visible blemish under 10x magnification.
VVS1 (Very, Very Slightly Included 1)Inclusions are extremely hard to see using 10x magnification.
VVS2 (Very, Very Slightly Included 2)Inclusions are difficult to see using 10x magnification.
VS1 (Very Slightly Included 1)Inclusions are slightly visible using 10x magnification.
VS2 (Very Slightly Included 2)Inclusions will not affect the beauty of a diamond but can be detected using 10x magnification.
SI1 (Slightly Included 1)Inclusions are slightly visible using 10x magnification.
SI2 (Slightly Included 2)Inclusions are noticeable using 10x magnification and most will be visible to the naked eye.
I1, I2, and I3 (Included)Inclusions are very obvious using 10× magnification and to the naked eye.
Diamond cut is very important as it impacts the overall look and value of a stone. The cut of a particular stone is rated based on how successfully a stone interacts with light to create the following effects.
At The Carbon Culture the GIA certified diamonds we sell are only rated as excellent or very good.
Diamonds can be cut into virtually any shape. However the diamond shape is typically decided by the diamond cutter depending on the rough stone. A Sarin machine is used to analyze and mark the rough stone for the optimal shape that will yield the largest stone with the least amount of cutting waste. At The Carbon Culture we like to have fun with our jewelry and create special pieces with unique shapes.
