3mm 4mm Yellow Color HPHT Lab Grown Colored Diamonds For Cutting Fancy Melee Diamonds
Lab Grown Colored Diamonds Description
Synthetic diamond is mainly produced by high pressure and high
temperature (hPTP) and chemical vapor deposition (CVD) methods. And
its quality is similar to natural diamond. Artificial diamonds are
often used to process priceless jewelry.
Over the past decade, laboratory-made diamonds have received
widespread attention because it allows for new applications of many
diamonds that have previously been considered too difficult.
Artificial rough diamond is an environmental protection product,
100% of which is free of conflict.
With the progress of human science and technology, scientists moved
the natural diamond growth environment into the laboratory,
simulated the whole growth environment of diamonds with high
pressure and high temperature, and used gravel sized diamonds as
seeds to grow. Diamonds grown in the laboratory are manufactured by
advanced processes such as high pressure and high temperature
(hPTP) and chemical vapor deposition (CVD).

Lab Grown Colored 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.
