About Us

Iridescent Stones is an independent gemstone encyclopaedia created for collectors, jewellers, students, and curious readers across the United Kingdom and beyond.

Our mission is to provide clear, organised, and practical gemstone guidance, including colour, hardness, care, origin, and identification information.

We aim to keep every profile accurate, transparent, and easy to navigate. Where affiliate links appear, they help support the running costs of the site.

Data Sources & Classification Standards

Our gemstone data model is informed by established gemological and mineralogical references used for educational comparison and classification.

Sources include Gemological Institute of America (GIA), Gem-A (Gemmological Association of Great Britain), and Mindat mineral records.

We also review frameworks from the International Gemological Institute (IGI) when aligning terminology and educational context.
