Pale Green Augelite Cluster - Yukon, Canada #283035

This is a gorgeous cluster of pale green augelite crystals with colorless quartz and gold-brown siderite from the famous lazulite deposits of Rapid Creek in Yukon, Canada. It even contains lazulite in a small cavity on one edge. This specimen comes with an acrylic display stand.

Augelite (chemical formula Al2PO4(OH)3) is an aluminum phosphate mineral that occurs as a product of metamorphism in phosphate-bearing sedimentary rocks, in granitic pegmatites, and in veins of high-heat hydrothermal ore deposits. Crystals can be colorless or exhibit green, yellow, white, blue, pink and red coloration, depending on impurities present during formation. Due to augelite's relatively low hardness and brittle tenacity, it is seldom used for faceting into a gemstone.
