About Diamond Tester

 As HPHT method involves using metal catalyst, it is hard to avoid some metals entering the crystal during growing process, so HPHT diamonds might be magnetic. And if the magnetism is too strong, diamonds will not be able to pass the diamond teste. Because CVD diamonds are formed by mere gas, they can be produced without magnetic and are able to pass the diamond tester pen.

lab made diamonds

 More recently, the Geophysical Laboratory of the Carnegie Institution of Washington, USA achieved a CVD synthesis rate of 100μm/h to produce a 10ct, half-inch thick single-crystal diamond.

 To further increase the size of lab grown diamond crystals, it is possible to grow colorless diamond single crystals in three dimensions at the inch scale (approximately 300ct) by sequentially growing them on six faces of the diamond substrate using CVD. High-pressure, high-temperature heat treatment has also been found to improve the color and hardness of synthetic CVD diamonds.
