What is CVD/HPHT Lab Grown Diamonds?
CVD is an acronym for chemical vapour deposition and HPHT is an
acronym of High Pressure High Temperature. This means that a
material is deposited from a gas onto a substrate and that chemical
reactions are involved.
What is difference between CVD & mined diamond?
The only difference between CVD Diamonds and mined diamonds is the
point of origin.
Mined diamonds take millions of years to grow under the earth, whereas CVD Diamonds are a high technology product which grows in a matter of weeks. Since it is created in laboratory it comes without flaws and is by far of better quality. Cannot predict the quality standards, a complete flawless natural diamond is very very rare and highly expensive.
What is the Eco-Friendly and Conflict Free Lab Grown Diamonds?
Lab Grown Diamonds grow above the earth in a diamond lab and unlike mined diamonds; there is no excavation and mining hence keeping nature and natural resources intact. This contributes in green environments.
