Amora Gems are sold by diamond equivalent carat weight, with the price per carat determined by color and clarity.
Base pricing is currently $425.64/ct for F color, VS clarity for Eternity Amoras. This pricing is valid until Dec 1st, 2018.
Cushion cuts and other Fancy cuts will have increased pricing to reflect that Cushion H&A for example, takes 3x as long as a Super Ideal Eternity H&A.
There are respective color and clarity premiums and discounts which affect the final per-carat price.
Below is a simple chart which you can use to determine pricing.
1 - Select the color you want to get the base per carat price.
2 - Select the clarity premium or discount to get the final per-carat price
3 - Blue and Pink do not have clarity premium or discounts. In Fancy Color diamonds, only the color is what is most important as the color hides most clarity unlike whites.
D color premium varies based on availability: For several months of initial production we had no D color at all. Currently we have some small amounts of D color, however it remains our rarest color grade.
We have no control over what the yield of D color is from batch to batch and thus this premium will fluctuate based on available supply.
Also note that D color becomes incredibly rare for sizes over 9mm, so there may be an additional rarity premium if/when we have D color in those larger sizes.
