Monazite-(Ce) (color change twinned crystals!)

Item Description

Monazite gets its name from the Greek word "monazein", which means "to be alone", in allusion to its isolated crystals and their rarity when first found. Monazite is usually found in granitic pegmatites, but these crystals are found in hydrothermal tin veins where is an absolute absence of Thorium (usually a trace element in Monazite). This is an attractive, very well crystallized, ridiculously rare, specimen consisting of sharp, lustrous, translucent, orange-pink, butterfly twinned crystals on Monazite-(Ce) measuring up to 6.5 mm! sitting on prismatic, gemmy colorless Quartz matrix. The size of the twins are large for the locality! These are some of the most distinct and impressive twinned Monazite crystals I have seen from Bolivia, and are certainly better formed than the majority of the Monazites I have seen from this famous locality. The crystals actually perform a color change in different lighting ranging from orange-pink to a white/yellow depending upon the light source. It is very difficult to obtain any specimens of this incredibly beautiful and rare phosphate, especially in crystals from Bolivia like this. This piece is from the same mine for which this material was discovered along the Contacto and San Jose veins in this mine and was first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find matrix specimens of Monazite-(Ce) from any locality in Bolivia or anywhere else in the world. This species is often dark and opaque from most localities and rarely bright like these. Priced at $1,450 in the inventory.
