Fancy Cut Lab Diamonds Description

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. HTHP and CVD are the two main methods for making laboratory-grown diamonds. High temperature and high pressure method (HTHP) uses graphite as raw material. HPHT diamonds are manufactured at a pressure of 5-6 GPA (approximately the pressure produced by a commercial jet landing on a human fingertip) and a temperature of 1300-1600°C. CVD diamonds come from various gases, such as methane. They are stored in a vacuum chamber, which decomposes the molecules of the gas, and then these molecules gather on the pre-existing diamond seeds.

After polishing and cutting lab-grown diamonds are same as natural diamonds. they have the same brightness and fire.

Round cut is the most common cut. Fancy shape diamond is different from round cut diamond. After cutting, it has different shapes, such as princess diamond, heart diamond, oval diamond, pear diamond, etc. Fancy diamond cutting began in ancient times, and has become a trend and fashion nowadays.

Water drop cutting, also known as pear cutting, is a hybrid cutting method. Based on the traditional structure of round bright diamond, it combines the advantages of oval cutting and olive point cutting. The cut gem looks like a crystal clear tear, with a round end and a sharp end. Compared with other shapes of diamond, the ratio of length to width of water drop shape diamond depends on personal preference. Many shapes are acceptable, and the appropriate ratio of length to width of water drop shape diamond is 1.50-1.75.

Lab Diamonds Introduction

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough 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 Rough Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Rough 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.
