Gypsum w/ movable bubbles on Goethite (RARE) ex van Tichelen

Item Description

A stunning and RARE pseudomorph combination from the ancient mines at Lavrion and the Wouter van Tichelen Pseudomorph Collection. A fantastic, sculptural, 6.9 cm, water-clear, well-striated, doubly terminated gypsum crystal has dramatically grown on a stalk of goethite replacement (pseudomorph) after a gypsum crystal. Small gypsum crystals on the stalk add much character. This is a dramatic piece on its own, balanced and poised. It is a gypsum, a pseudo, and a specimen all. AMAZINGLY, the striking gypsum crystal hosts two elongated enhydros (fluid pockets) with movable air bubbles! Rare, perhaps UNIQUE, pseudomorph combination material, especially with movable bubbles as a bonus. The piece is in pristine condition. This is from the most important general pseudomorph collection built in Europe to our knowledge. Valued...? Never seen anything comparable, really, with such aesthetics from here.
