Natural Loose Andalusite Gemstones – Rare Pleochroic Green to Red

Andalusite is one of nature's most fascinating and underappreciated gemstones, celebrated for its remarkable pleochroism — the ability to display multiple colours simultaneously depending on the viewing angle. In a single stone, you may see rich earthy greens shifting to warm reddish-brown tones, all without any treatment.

Our collection features individually selected natural andalusites in baguette, trap cut, oval, and drop cuts, ranging from 1.01ct to 2.15ct. All stones display the characteristic green-to-red colour shift that makes andalusite so distinctive and collectible. Sourced from premier deposits in Brazil and Sri Lanka.

Andalusite rates 7–7.5 on the Mohs scale, is typically untreated, and makes a truly unique centrepiece for bespoke jewellery — a gem that genuinely stands apart from the crowd.
