Loupewise, the Gemologist’s Toolkit
A gemstone-identification engine that turns refractometer, specific-gravity, UV, and other instrument readings into a ranked list of candidates.
Field notes
Loupewise organizes identification around measured properties rather than appearance. The homepage describes a candidate-ranking process that starts with readings such as refractive index, then selects a potentially useful next test from 15 instrument and observation categories. Its stated reference layer covers 130 species and varieties with 48 data points per entry, including inclusions, simulants, treatment detection, and natural-versus-synthetic protocols for 33 species. Study modes are listed for GIA, Gem-A FGA, and FEEG examinations.
