Its become a very competitive business with everyone trying to come up with their own "Branded" diamonds, and jewelry and design, the so called Calla Cut is nothing more than a modified round stone it appears, this is the first I have heard of it, similar to an Ascher Cut which came out a few years ago and then just died!!! No one is buying Aschers anymore and the same will happen to this Calla. A cutter can make much more money with a "new" designer cut diamond and promote it, hopefully someone will fall in love with it and pay 30-40 more money than it should be.

If you love the cut then I would say go for it but be aware that the actual value will never come back to you since it is not main stream. over time, the round diamond has proven itself the most popular. We have sold many princess cut diamonds the past 5 years but even those have slowed down. We almost never sell any marquise diamonds lately, all these cuts are cyclical, the round diamond has been most consistent.

The Jeweler who told you about certified cut may have meant that he cant distinguish the table and the depth to determine if the diamond is a good cut or not. More than likely he is blowing smoke and trying to get you to "doubt" the Calla Cut. When a diamond is sent to the laboratory such as the Gemological Institute of America (GIA) or European Gem Labs (EGL) they are evaluated for Color Cut Clarity Carat Wt. hence the "4 C's" of the diamond. The cut or of the table and depth ratios are the reason the diamond has "fire" or lacks "fire".
