Prehnite, Diopside

Jeffrey Mine, Val des Sources (Asbestos), Quebec
Size: 4.3x2.7x4.0 cm
Largest crystal size: 30 mm


This specimen features a stunning, for the mineral, single, sharp, white euhedral prehnite crystal nestled in a bed of olive-green prismatic diopside. Most prehnite is typically botryoidal or a replacement of earlier-formed crystals, and it is usually green. Well-formed, colourless crystals like this one are a real rarity. This specimen comes from the renowned and long-closed Jeffrey Mine and was once part of the collection of the legendary Rock Currier (includes the original label). Excellent for the mineral!

The Jeffrey Mine, began operations in 1879. Global demand for asbestos plummeted in the 1980s due to the recognition of its carcinogenic properties and subsequent worldwide bans on its use as a building material. Financial resources were ultimately depleted in 2001, leading to the mine's closure and inactivity since then.
