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.
Oval cut diamond is based on the traditional structure of round
brilliant cut. Oval diamond has the same beautiful brilliant color
as round diamond. Oval diamond because of its length so as to
highlight the slender fingers of women, so it is also a very
popular diamond shape. The perfect golden ratio for an oval diamond
is 1.5:1, which means that the length is about 1.5 times the width.
If the aspect ratio is greater than 1.5, a dark area will appear in
the middle of the diamond, which is called the bow effect. This
kind of diamond is not ideal. If the ratio is less than 1.5, the
diamond looks like a deformed round diamond. For cutting, the best
depth ratio is 59% - 63%.

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.
