HPHT Lab Made Uncut Rough White Lab Diamond Description
What is CVD HTHP diamond?
Lab Grown Diamond is also widely known as HTHP diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). Under HTHP method, purest carbon is given the same environment into the lab so that it can convert into the diamond and in CVD method, the atmosphere is created which leads to atom by atom formation of diamond.
The difference between mined and lab-grown diamonds is indistinguishable to the naked eye, only a trained gemologist using specialized equipment can spot the difference. The price difference between mined and lab-grown diamonds is in the range of 30-70%, with lab-grown diamonds being cheaper and free from impurities.
It is a common misconception that lab grown diamonds are of inferior quality, but with advanced technology, they are made of even better quality than mined diamonds. There is also the misplaced notion that diamonds are expensive due to polishing and other processes. But as lab grown diamonds are made from scratch, it is relatively cheaper. Due to the price difference as well as the superior quality, lab-diamonds are being increasingly preferred over mined diamonds.

HPHT Lab Grown 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.
