Prehnite cabochon

Prehnite cabochon

Size: approx. 40x25mm

Weight: 63.40ct

Soft green, slightly more yellow green in the transparent bottom part, with darker green inclusions.

A really lovely example - Prehnite is a translucent green gemstone which often has mineral inclusions like these epidote inclusions seen in this stone.  It is the first mineral to be named and described as coming from South Africa and the first to be named after its discoverer, Colonel Hendrik van Prehn, a Dutch commander of the military forces of South Africa.

With a hardness of 6-6.5, fair to good toughness and good stability, it is better suited for use in pendants, earrings and brooches but care should be taken in rings and bracelets and when setting the stones themselves.

• Hardness – resistance to scratching and wear
• Stability – resistance to alteration by light, heat or chemicals
• Toughness – resistance to fracture, cleavage or cracking
