Diamond Carat Weight

Diamond weight is expressed in carats ( one carat is equal to 200 milligrams). Carats are divided into 100 points, so a 0.78ct diamond is called a 78 pointer. Another term used by diamond professionals is grain. One grain equals about 25 points, so a one-carat diamond can be called 1ct, or 100 points, or 4 grains.

Cut influences carat weight

Diamonds that weight the same may not have the same vertical spread, depending on how they were cut. Those cut too shallow or too deep will look small for their and/or have poor light performance. 

Frantz Diamonds have superior brightness, dispersion, contrast, and scintillation. Even when removed from jewelry store lighting and observed through the infinite panoramas of real-world lighting that we live in, Frantz Diamonds still sparkle like no other. They will be dazzling in bright light and have bold flashes of rainbow color in soft lighting, where other diamonds go dark.
