Briolette Cut Tearshape Hydrothermal Synthetic Peridot colour glass. 6x4 mm with passed throught drill on top.
Hydrothermal peridote glass are synthesized at relatively low temperatures and at high pressures from a seed crystal and an enriched solution of SiO2 and Thullium Oxide.
The optical and physical characteristics of hydrothermal quartzes do not vary from those of natural quartz. Only slight parallel growth lines can be seen inside the crystals and, rarely, some bubbles.
Our hydrothermal stones are characterized by having a perfect cut finish and a very good final polishing, so they offer a high quality shine.
Acceptable working temperature: NOT ACCEPTABLE FOR CASTING
