SERPENTINE (Clinochrysotile)![]() The name serpentine refers to a group of predominantly green minerals that occur in masses of tiny intergrown crystals. The two main types used in jewellery are bowenite (translucent green or blue-green) and the rarer williamsite (translucent, oily green, veined or spotted with inclusions). Infinite (right) is a combination of serpentine and chrysotile and comes from South Africa. Ophiolite Serpentine (the Lizard, Cornwall).
![]() Serpentine was one of the rocks thrust up from underneath the crust, which was rich in iron and magnesium. During its tortuous journey through the Rheic Ocean crust and onto what became of Cornwall, this rock, peridotite, was changed to serpentinite, or serpentine - one of the Lizard's most beautiful rocks. The above photographed "pebble" was found on Coverack Beach. The rock below, Kynance Cove.
