LEMON PREHNITE
FACETED
BRIGHT LEMON YELLOW COLOUR
PERFECT FOR SETTING IN JEWELRY
Prehnite is a phyllosilicate of calcium and aluminium with the formula: Ca2Al(AlSi3O10)(OH)2. Limited Fe3+ substitutes for aluminium in the structure. Prehnite crystallizes in the orthorhombic crystal system, and most oftens forms as stalactitic or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite. Very rarely will it form distinct, well individualized crystals showing a square-like cross-section, like those found at the Jeffrey Mine in Asbestos, Quebec, Canada. It is brittle with an uneven fracture and a vitreous to pearly lustre. Its hardness is 6-6.5, its specific gravity is 2.80-2.90 and its color varies from light green to yellow, but also colorless, blue or white. In April 2000, a rare orange Prehnite was discovered at the famous Kalahari Manganese Fields in South Africa. It is mostly translucent, and rarely transparent.

积极的I paid a lot for an item, but it’s my fault for not recognizing its true value. I will learn from this experience. The seller was honest and helpful.

it's ok and I am happy because I purchased it for recut it and have polished slice. 8 mm is too high for jewelry. Also the dome is too much rounded, color are better with low dome on this kind on stone
