SPECTRAL EVOLUTION spectrometers are ideally suited for mining exploration, mineral identification, and mining production. These spectrometers cover the UV/VIS/NIR spectra using three photodiode arrays with no moving parts. This makes them supremely reliable in the field. They can collect spectra in as little as 100 milliseconds.

About Moonstone. Moonstone is a variety of the feldspar-group mineral orthoclase. During formation, orthoclase and albite separate into alternating layers. When light falls between these thin layers it is scattered producing the phenomenon called adularescence. Adularescence is the light that appears to billow across a gem.
· Most gemstones are minerals or rocks and occur in favored sites in the earth''s crust or in the gravels that result from the weathering of rocks. Of the beautifully crystallized minerals that seem useful for gems, only a very few actually meet the standards, that is, are sufficiently beautiful, durable, rare, and large enough to be cut into salable stones.
