DEF Color HPHT Pear Shape Fancy Cut Lab Diamonds For Making Lab Diamond Earrings
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.
Round cut is the most common cut. Fancy shaped lab diamond, also known as gardener cut diamond, refers to diamonds other than standard round diamonds. The common fancy shape lab diamonds include pear shaped, marquise shaped, princess, radiant, emerald cut, heart, oval shape, etc.
Pear shaped diamond is also known as water drop shape. The diamond is pointed at the top and round at the bottom. It combines the advantages of oval cutting and round diamond cutting. Besides round cutting, it is one of the most popular special-shaped cutting methods. Tracing back to the history, the first pear shaped diamond can be traced back to the 15th century. After the baptism of time, pear shaped diamond has become more and more dazzling in the field of jewelry. Pear shaped diamond can modify the shape of the hand and highlight the beauty of the line of the female hand. In terms of cutting, there are high requirements for proportion, symmetry and diamond color.

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.
