## Overview

The TEKCOPLUS Handheld Diffraction Spectroscope is a compact, durable gemological tool crafted from aircraft aluminum. Measuring just 55mm, it features a high-quality grating that reveals gemstone absorption spectra, enabling swift and accurate identification of natural and synthetic stones, including diamond stimulants like YAG and Cubic Zirconia. Ideal for gemologists and jewelry professionals seeking portable, reliable spectral analysis in the field.

## Description

Detects the absorption of spectra and it is use to view the color of a gemstone, either by shining a light (pen-torch) through the stone into the spectroscope if the stone is transparent, or by viewing its reflected light if the stone is opaque. Inside is a pattern of lines that you must learn to recognize, it is a spectrum (rainbow) of which might be interrupted with black or white lines. Certainly another useful and best tool for gemologists to use in detecting iron and chromium and for non-gemologists the 'diamond stimulants' YAG and Cubic Zirconia give spectacular spectra and some Zircon. Other gemstones are more difficult to detect. Spectroscopes allows you to analyze a loose or mounted stone's spectrum. They help distinguish naturally colored diamonds from those that have been irradiated and help to distinguish natural stones from synthetics by the stone's selective absorption of certain wavelengths. Specifications: * Length : 55mm * Diameter : 18mm * Material : Aluminum (Durable) * Inside Instruction : Raster type Set Includes: 1 x Medium Spectroscope 1 x Synthetic Leather Carry Pouch

Review: 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.
Review: Worth it - Works well. Makes identifying your crystals easy to do. Nice leather case to keep it safe.

## Questions & Answers

**Q: What does a spectroscope do?**
A: 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).

**Q: How do I use it on gemstones?**
A: 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).

**Q: Which gemstones show clear spectra?**
A: Easy to spot: Synthetic CZ, YAG, zircon, and chromium-rich gems (ruby, emerald) ,Harder to read: Many natural gems have faint or complex patterns.

**Q: Can it detect fake or treated gems?**
A: Yes! It helps spot synthetic simulants (like CZ) and some treated diamonds (irradiated). / Natural vs. lab-grown gems may show slight spectral differences.

**Q: Is this spectroscope good for beginners?**
A: Yes! Compact (55mm), durable (aluminum), and includes a reference scale inside. Comes with a protective pouch.
