At present only natural and sometimes artificial crystals of sphalerite have wide application for jewelry. Meantime, crystals of eritrozincite and stilleit also have fine colours, large refractive index and may be applied as jewels. There are no enough amounts of good natural crystals, but now the problem is solved — we offer artificial analogues of all these gems. Besides, we can can controllable grow them with different colours.
