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.
