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. Round brilliant cut diamonds have 58 facets.  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.

Emerald cut is a typical step cut. All facets are parallel or perpendicular to the diamond's Square waistline. The shape is rectangular, the pavilion and crown are flat, and the bottom tip is linear. Because often used for gem emerald turner, so it is called this name.

Lab Diamonds Introduction

 

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
