Gemology ID
Perfect condition instrument, 11,312 entries in the database
User can add entries to the database very easily
Instrument passes its self-test, using the provided polystyrene rod Instrument is very easy to use
Perfect for chemical ID, gemology, polymer plastic analysis, etc
Please see examples of gems/stones identified using this instrument(pictures of actual stones analysed). The spectra is compared with the free available and recognised RUFF database: Almandine (garnet) Aragonite (calcium carbonate) Beryl aquamarine Sapphire (blue corundum) Fluorite Gypsum (calcium sulfate dihydrate) Leucophanite from Quebec, Canada, Tourmaline, Cerussite, Grassular and Titanite.
Instrument is provided with a WI-FI compact flash card, this means there is no need to take the card out of the instrument to export the data and analysis in a computer of in a smartphone
