Green Aventurine

quartzite with fuchsite (chromium mica) inclusions

A quartzite glittering with chromium mica, mined chiefly in southern India and sold in more starter kits than almost anything else. The name comes from Venetian glassmakers' a ventura, by chance, which is a reversal worth noting: the glass came first and the stone was named after it. People carry it for abundance, calm and self-love.

What it is

A quartzite glittering with chromium mica, mined chiefly in southern India and sold in more starter kits than almost anything else. The name comes from Venetian glassmakers' a ventura, by chance, which is a reversal worth noting: the glass came first and the stone was named after it. Cheap, hard, and reliably pretty.

What it is confused with

chrysoprase, jadeite-jade, green-goldstone, serpentine, amazonite

Opaque green with a distinctive glittery shimmer (aventurescence) from thousands of tiny reflective mica platelets, tilt it under a lamp and discrete points of light flash on and off across the surface. The green is mottled and slightly granular rather than smooth, and a hand lens shows individual green flakes suspended in a grey quartz groundmass. Grainy, sugary fracture surfaces, not conchoidal, because it is a rock rather than a single crystal.

How to tell

Under 10x, aventurine's sparkle comes from irregular green mica flakes of varying size, while green goldstone's sparkle is a dense uniform cloud of identical copper-chrome specks in transparent glass with visible bubbles. Aventurine scratches glass and is opaque with granular texture.

Natural green aventurine is untreated. Blue and red 'aventurine' is often dyed quartzite; green goldstone is a manufactured glass sold alongside it.
