Will the coating chip off or can it even be scratched?

No, because the type of diamond used in the molecular process for particle coating is an Amorphous Diamond instead of a Crystalline Diamond. Our process has 90% of a real diamonds molecular structure and so has its characteristics.the amorphous diamond is actually infused into the upper layers of the core, so it is more than just a surface coating. It actually integrates into the core itself.

Due to the inherited characteristics of amorphous diamond, its molecular structure greatly impedes delaminating or removal of the surface as the coating in ordinary use for jewelry purposes. For this reason this type of diamond was chosen for use due to its superior characteristics. No others compare with our product which have been tested and compared by other leading suppliers. Ours is a fully patented technology in application, winner of a leading science and innovation award in 2001, our rivals can not compare.

Is Asha a different kind to yours? Do you sell them ?

'Asha' Diamond simulant is a brand name, just like ours 'JH' Diamond simulant. They are the same kind, same technology called Nanofilm technology.

We don't sell Asha's diamond, we only sell our own brand - JH Diamond.

How and when do you deliver?

Loose stone that are in stock normally ship within two business days.

For all other items, it takes 1-2 weeks depending on how busy our workshop is. Once the order is packed and ready, we ship your order and email you the couriers Tracking number.

We normally use EMS for orders inside China, UPS International (which typically takes 5 business days shipping) to all other countries (note that additional international shipping charges apply).


Will your diamond test positive on a diamond tester?

No, it will not. Even though the exterior contains Amorphous diamond, it also contains some SP2 bonds instead of only SP3 as in natural diamond gemstone. Thus, the heat signature is different and this is reflected when testing by a diamond tester. Traditional diamond testers simply measure *heat conductivity*.
