FAQ
What are Lab Diamonds?
We all know what natural diamonds are. We will use a comparative approach to explain what cultivating diamonds is, and it will be very easy for everyone to understand.Firstly, let's talk about their similarities. They are all real diamonds, certified by authoritative institutions around the world.Cultivated diamonds, like natural diamonds, contain carbon elements.
Secondly, We explain their differences. Natural diamonds are formed over thousands of years under natural conditions; Cultivating diamonds is a process of imitating the growth environment of natural diamonds and using machines to cultivate them in the laboratory in several months.
What is different between Lab Diamonds and Nature Diamonds? Can I tell the different?
The difference between a lab diamond and a natural stone is not how they look, but how they are grown. Natural diamonds are grown in the earth for several millions or even billions of years. Lab-grown diamonds are grown in a machine for a few days to months depending on the size.
Normally, it’s hard for a trained jeweler to tell the difference between a lab grown diamond and a natural stone.
How are lab grown diamonds graded?
Lab grown diamonds can vary in color as clarity grades just like natural diamonds.
How Are Lab Grown Diamonds Made?
Currently, there are two ways lab grown diamonds are created, the HPHT(high pressure high temperature) and CVD(chemical vapor deposition)methods.
* The HPHT process closely mimics the conditions that diamonds need to form naturally, but they do it much quicker.
* CVD diamonds grow from an HPHT grown diamond seed crystal. Carbon rains down from a plasma cloud and deposits onto the seed crystal, growing diamond in layers.
Both processes produce the same gem quality lab diamonds. However, the CVD process is becoming more common in the industry because it's more cost-effective and the machinery is a lot smaller.
We sell both HPHT and CVD diamonds.
