Prase Quartz - Serifos, Greece
 
 Prase crystal in artichoke-like formation from the world-famous deposit on Serifos. In the lower part of the crystal, the piece has the characteristic leek-green color, which gave this quartz variation its name (derived from the Greek, prason = leek). Towards the tip, the crystal becomes wonderfully transparent. For several years there has been a strict ban on collecting minerals on Serifos.
 A nice European classic.
 Historical specimen from the Josef Kolb collection.
