It is used to display the color of a gemstone by shining a light (pen-torch) through the stone into the spectroscope if the stone is translucent, or by showing the reflected light if the stone is opaque.
Spectroscopes are used to examine the spectrum of a loose or mounted stone.
Within is a series of lines that you must learn to recognize; it is a continuum (rainbow) of which black or white lines can be broken.
The stone's selective absorption of certain wavelengths helps differentiate naturally colored diamonds from those that have been irradiated, as well as natural stones from synthetics.
Characteristic of the item that can be highlighted
- Compact, pocket size makes it great for traveling
- Handy -Bring it with you on buying trips, vacations, or to trade shows
- Made of aircraft aluminum & finest optics.
The total package includes
- 1 x Medium Spectroscope
Can a spectroscope detect rough gems?
Yes, spectroscope is also a great asset for examining rough gems, when getting RI readings is difficult, and detecting some treatments
A spectroscope will show you the wavelengths of light emitted, or reflected, from a gem
Set Includes:
1 x Medium Spectroscope 1 x Synthetic Leather Carry Pouch

It Works great and accurate. It would help a Novice to have instructions added to shipping.

Works in a pinch. This unit is well suited for "in the field" use.

A good study tool, but a bit pricey.

Disappointed that there is no scale provided, making it incomplete as a gemologist tool. But I may be able to use it with time.

Could not determine the wave length of gems using this.

I am an amateur on this. I had to rely on YouTube to use. Still very shaky ,but better!

This little instrument makes a huge difference for identifying fakes from authentic stones!

does what it says but if it was a little bigger would be easier to handle

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.

Small and handy, I use it,for checking spectral output of modern lighting systems. Particularly examining high blue emission.

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