Spectrocope
It's not what I thought it would be because the add says diamond tester and tests opaque but it doesn't test in that way but it is good for the real test it does as a spectrum light test

As expexted
Might be useful if it included a pictorial guide to some of the different elements so any novices get some idea what they are looking for/at

Produces poor spectra
Single line emission shows multiple lines. Lines are very broad, making it extremely hard to see spectra using this device. Would not recommend.

Best for the money!!!! Gem identity +
Great for the price very accurate with full sized view of spectrum. Identify gemstones with a great tool comparable to Gem- A spectroscope. Professional quality at a decent price this not a toy. Is as good as Gem-A. GIA approved one that goes for double. Great precision optics and shows full spectrum no scale. Great for gemological research and any other purpose. Move back to veiw full spectrum!!! Doesn't have grating lines but is still great.
