About Lab Grown Diamond
Diamonds have always fascinated people, from the past to the present. People have worn them to commemorate the miraculous brilliance and strength created by nature.
On the other hand, as times change, new values and major changes in the environment that cannot be overlooked mean that the things we have benefited from in the past can no longer be taken for granted, and we can no longer ignore many environmental issues.
The fact is that diamond mining involves the destruction of mines, which leads to huge financial costs, conflicts, and child labor.
Lab-grown diamonds are diamonds that are produced in clean, modern laboratories using cutting-edge research and technology. They have the same properties and characteristics as natural diamonds, except that the environment in which they are produced is different.
It is now possible to reproduce the true glow on the ground.
About Us
We basically do made-to-order production because we want our customers to use the special items they need for a long time.
The diamonds we handle are limited to the highest grade (DEF color, VS1 or higher).
