GemRI

Identify gemstone species from refractive index and specific gravity measurements

Scientific AIFreemium

GemRI cross-references measured refractive index, birefringence, specific gravity, and fluorescence response against a database of 380 gemstone species and varieties. The tool disambiguates visually similar species such as tourmaline-emerald or spinel-ruby using multi-property constraint satisfaction. Treatment detection flags synthetic and enhanced stones based on inclusion pattern analysis from photomicrograph uploads.
