Color, Clarity, & Carat

Moissanite Color

We sell Moissanites in the colorless and near colorless range. GIA has developed a color grading scale which is commonly used in diamonds, and the same scale can be applied to Moissanite. According to the GIA scale

  • Grades D, E, F: colorless
  • Grades G, H, I: near coloress
  • Grades J, K: faint color

So what does that mean in practical terms? Grades D, E, F and even G are colorless and can be described as \icy\" white. Grade H and I still look white but its a slightly warmer or steely white. When you get into the J and K range you will start to see a bit of yellow.

Moissanite Clarity

Clarity is a measure of the surface blemishes and internal inclusions of a gemstone. For the purpose of comparison to natural diamonds, experts agree the clarity of Moissanite is on average the equivalent to VS clarity on the GIA scale. What this means, in reality, is inclusions can only be seen under magnification, and under a jewelers loupe (10x magnification) are difficult to see. Less than 10% of faceted diamonds have this level of clarity.

Moissanite Carat

The carat is the traditional unit of measurement for a diamond's weight. Moissanite is typically not described in its actual carat weight because it weighs approximately 10% less than diamond. For example, a 6.5mm round diamond would weigh 1.0ct while a 6.5mm round moissanite weighs ~0.88ct. The two stones, Moissanite and diamond, are the same size, but two different carat weights. To minimize the confusion this causes, Moissanites are listed with their size in millimeters and the diamond equivalent weight in carats. This way, a 1ct round diamond and a 1ct round Moissanite are the same size.
