Calcite and scheelite cabochon

Size: approx. 27x18mm

Weight: 18.20ct

Varying tones of dark to light denim blue with pale taupe.

Also marketed as ‘Lapis Lace Onyx’, it does not contain either lapis or onyx – the white is calcite and the blue is scheelite.

Scheelite has a hardness of 4.5-5 while calcite has a hardness of 3 making this stone suitable for earrings, pendants and brooches but unsuitable for rings or bracelets and care needs to be taken when designing for this stone and when working with it.
