HPHT/CVD Diamond – Page 3 – Lab Grown Diamond

Collection Of Lab Grown Diamond – GIA Certified

We all love diamonds. These shiny stones look awesome as pieces of jewelry on your body. We all know that diamonds come from mines, but did you know that there is even better quality lab grown diamonds available? These diamonds are physically, optically and chemically similar to mined diamonds, the only difference being that they are produced in a lab.

There are 2 ways in which lab grown diamonds are made-

High Pressure High Temperature (HPHT) – This process imitates the way diamonds are produced naturally. A carbon ‘seed’ is placed in a press which is specially made and is given a high pressure with high temperature of about 1400 Degrees Celsius to produce high quality diamonds which can be used either for jewellery manufacturing or industrial uses.

Chemical Vapour Deposition (CVD) diamonds – Developed in the 1980s, the CVD procedure does not require pressure, instead, it involves the heating of a mixture of hydrocarbon gas (generally methane) and hydrogen in a vacuum of extremely low pressures. The resultant diamonds are free from any chemical inclusions or other impurities.

Benefits of Buying Lab grown diamonds-

It’s an exciting new trend- Although Lab grown diamonds have been around since decades, it was only in the recent years that their popularity has skyrocketed. It is the latest trend amongst all stakeholders in the diamond industry, whether you are diamond jewellery manufacturer or an industrial user of diamonds
Low costs- Lab grown diamonds are much cheaper than traditional mined diamonds- you can save about 10-30% costs with a lab grown diamond vis-à-vis a mined diamond. This is making lab grown diamond ever more popular amongst the masses.
No worry of unethical manufacturing practices- Lad grown diamonds do not carry the baggage of unethical mining practices which are associated with mined diamonds. Lab grown diamonds are produced in a controlled environment and are not subject to chances of human trafficking and funding of civil unrest as is the case with mined diamonds.

GIA Certified HPHT Diamonds For Sale

There are two ways in which lab grown diamonds are produced. High Pressure High Temperature or HPHT diamonds are produced mimicking nature. Carbon is exposed to high temperatures in excess of 1400 Degrees Celcius and given high pressure to get diamonds that are of much better quality than mined diamonds. The other way diamonds are lab produced is through the Chemical Vapour Deposition process or CVD where methane and hydrogen are heated in a vacuum chamber at extremely low pressures. This results in the formation of diamonds which are free from any chemical inclusions or other impurities.

Why should I buy HPHT diamonds?

Even though HPHT diamonds are made in the lab they are technically diamonds. They are optically, physically and chemically characterized as diamonds. Except with professional help, it is impossible to make out the difference between lab created HPHT diamonds and mined diamonds. The cherry on the cake is that these lab produced diamonds are much cheaper than their mined counterparts.

HPHT diamonds

Pros

HPHT diamonds are ‘true’ diamonds, i.e. they are indistinguishable from mined diamonds.
They are cheaper than mined diamonds
HPHT diamonds are of the best quality available- They are of much better quality than mined diamonds

Cons

HPHT diamonds tend to be magnetic
These stones can show hints of colour from the side on close inspection.
Many times these stones are mis sold as high quality diamonds to command a better price.
