Who are we?

JH diamond trading company limited is primarily a wholesale jewelry company. We specialize in the sale of loose coated diamond simulantes. This is an award winning patented hi-technology process of molecular transference and bonding.

Using this technology we create high-end core infused CZ within the inner and outer molecular layers of the material. The outer layer consists of extremely pure man-made amorphous diamond, a pure carbon with 90% of real diamond molecular bonds. Our process uses extremely pure amorphous diamond ions which completely coats the exterior CZ surface as well as into the solid CZ its self enhancing its atomic composition. This new and unique technology process can not be duplicated or replicated anywhere by any other supplier or process except by JH Diamonds. We are the sole owner and supplier of the applications technology and patented licensed use.

We offer a large selection of loose diamond shapes and colors at wholesale prices. As a wholesaler, we bring you unbeatable value anywhere, expert customer service, convenience, and a quality selection to choose from, of either loose stones or in a limited final fashioned product as wearable jewelry. Consider why pay retail prices when you can buy direct? At JH Diamond, we deliver affordable elegance at unbeatable prices, so you always wanted a full 1 Caret diamond but can’t justify the cost, we have your solution, it looks, feels, shines the same as 100% diamond, only the jeweler as an expert can tell the difference and only by conducting tests, not by visual examination alone, so effective is our coating and bonding process it takes special sensitive equipment to tell the difference.

We are based in Shanghai purely for convenience; our production is done in Singapore to strict quality control and patented technology a spin off from space craft technology process of coating, that also insures the best quality of our JH Diamonds.

To save you money and on cost charges, we deliberately do not have an expensive high street shop to maintain and this enables us to pass on massive discounts to our buyers both in bulk or single item. You won’t believe our prices. Its not cut and polished fine crystal glass or cz, it has an actual diamond coating layer, it shaped by skilled craftsmen then 21st century technology enhanced. There is nothing like it, it’s new, it’s as good as the real thing but it’s at very affordable prices and you can own them.
