Excellent Cut HPHT CVD IGI Certificated Fancy Cut Synthetic Diamonds For Making Diamond Jewelry
Lab diamonds are real diamonds. Carbon is the main element of natural and laboratory-grown diamonds. The chemical and physical properties of synthetic diamonds are same as natural diamonds in terms of hardness, thermal conductivity, and strength. After polishing it's difficult to distingush lab diamonds and natural diamond by naked eyes.
Round diamonds are by far the most common and popular diamond shape. It also gives people more flexibility in balancing cutting, color and clarity. Its fire is beautiful and diverse, which is the most attractive. Brilliant cutting reflects most of the light. It is also known as the most brilliant and colorful cutting method.

Besides Round cut, the common fancy shape lab diamonds include pear shape, marquise shape, princess shape, radiant shape, emerald cut, heart shaple, oval shape, etc.
Oval brilliant cut diamond has thin and narrow cutting lines at both ends, which condenses the light of diamond to the extreme. The cutting workers mainly consider the requirements of aspect ratio. Generally, the aspect ratio of 1.75:1-2.25:1 is the best. This kind of cutting has low retention rate of raw stone, and its characteristics are at the sharp corners at both ends, where the inclusions can be better covered, and the high brightness at the sharp corners.
