What does a spectroscope do?

A spectroscope splits light into a spectrum, showing dark or bright lines that help identify a gemstone’s composition (e.g., chromium in rubies, iron in sapphires).

How do I use it on gemstones?

1.Transparent stones: Shine light through the gem into the spectroscope. 2.Opaque stones: Analyze reflected light. 3.Look for absorption lines (black) or emission lines (bright).

Which gemstones show clear spectra?

Easy to spot: Synthetic CZ, YAG, zircon, and chromium-rich gems (ruby, emerald) ,Harder to read: Many natural gems have faint or complex patterns.

Can it detect fake or treated gems?

Yes! It helps spot synthetic simulants (like CZ) and some treated diamonds (irradiated). / Natural vs. lab-grown gems may show slight spectral differences.

Is this spectroscope good for beginners?

Yes! Compact (55mm), durable (aluminum), and includes a reference scale inside. Comes with a protective pouch.

Works, focus point is a little small, have to pretty much put it on your eye but gets the job done

Crap images taken just holding it up to my phone, I will upload better images later when its mounted into equipment.

À retirer de la vente tel quel

L'instrument par lui-même peut marcher à condition de savoir précisément comment s'en servir. Or aucun mode d'emploi ni notice. Même sur le site du fabricant il n'est pas clairement référencé. Sur YouTube on trouve une "démonstration" mais en japonais (ou chinois?) donc incompréhensible pour la plupart des occidentaux dont je suis. De plus c'est mal filmé (de trop loin) et on ne distingue pas bien ce qui se passe. Plus encore, il est mis en œuvre un système d'éclairage très très lourd (fibre optique?), qui, s'il est nécessaire, grévera fortement le prix de la mesure du spectre. À revoir complètement, même la description de l'instrument sur Amazon est indigente. J'aurai dû mettre 0 étoiles.
