Product attribute:

1.We select domestic high grade single crystal diamond as raw material.Its static pressure resistance,abrasion resistance and thermal stability precede the industry stanards.

2.The crystal is almost in round shape.There are few particles being adsorbed on the surface as well as no niddle-like or plate-shapped particle.

 Recommended usage:

the diamond is used in industries which have high requirement of grinding and polishing and surface finishing,such as precise instrument industry and they are also applied to those industries which have high requirement of  impurity  content, including plating,diamond compact.

 Item: big size synthetic diamond (YWD)

  Size: 1.0mm, 1.5mm, 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm

 Weight:   1ct for 1pcs 1ct for 3 pcs1ct for 5pcs, 1ct for 7pcs, 1ct for 8pcs, 1ct for 9pcs, 1ct for 12 pcs, 1ct for 17pcs etc.  

 Grade:   YWD 20, YWD 40,  YWD 80,  YWD 90 YWD 91 for different purity.

 YWD 90 and 91 is the best quality stones made in lab condition, the production quantity will be few, but can achieve gemstone grade, the hardness is same with natural diamond, so our  90 and  YWD 91 synthetic diamond can be used as jewelleries.

 Application:

jewellery processing tools, dressing tools, petrol drilling, construction, engineering, mechanical processing etc.
