Measuring just 55mm in length, it features a high-resolution grating to reveal unique absorption spectra, enabling professionals and enthusiasts to distinguish natural gems from synthetics and detect diamond stimulants like YAG and Cubic Zirconia. Lightweight and portable, it includes a synthetic leather pouch for easy transport, making it an essential instrument for gemologists on the move. ## Description tects 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.

Enhance your gemological expertise and make informed decisions with this exceptional instrument by your side - EASY TO USE: The Pocket-Sized Spectrometer wavelengths that are absorbed by the stone are seen in the spectroscope as verticle black lines in the spectrum. Each stone has a unique absorption spectrum (like a fingerprint of the stone) When identifying a stone we look for a spectrum that is characteristic for that stone - Note: This product does not include the gemstones mentioned. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072R2QH8L | | Adjustable Length | No | | Are Batteries Required | No | | Batteries required? | No | | Brand | TEKCOPLUS | | Brand Name | TEKCOPLUS | | Color | Spectrometer | | Colour | Spectrometer | | Customer Reviews | 4.1 out of 5 stars 93 Reviews | | Display Type | grating | | Extended Length | 55 Millimeters | | International Protection Rating | IP54 | | Item Dimensions L x W x H | 8.1L x 7W x 4.6H centimeters | | Item Type Name | Spectrometer | | Item Weight | 0.04 Kilograms | | Item weight | 0.04 Kilograms | | Manufacturer | TEKCOPLUS | | Manufacturer Part Number | GSTK-94 | | Material | Acrylonitrile Butadiene Styrene | | Material Type | Acrylonitrile Butadiene Styrene | | Model Number | GSTK-94 | | Power Source | Battery Powered | | Power source | Battery Powered | | Recommended Uses For Product | Gemstone Identification | | UPC | 713072682851 | | Unit Count | 1.0 Count | | search coil size | 25 Millimeters | ## Product Details - **Batteries required?:** No - **Brand:** TEKCOPLUS - **Colour:** Spectrometer - **Material:** Acrylonitrile Butadiene Styrene - **Power source:** Battery Powered ## Images ![TEKCOPLUS Handheld Diffraction Spectroscope, Pocket-Sized Grating Gemological Spectrometer in a Gem Tool Jewelers Eye Loupe for GIA Use and Quick Identification Gemstone Jewelry Magnifier - Image 1](https://m.media-amazon.com/images/I/61-HD36H6DL.jpg) ![TEKCOPLUS Handheld Diffraction Spectroscope, Pocket-Sized Grating Gemological Spectrometer in a Gem Tool Jewelers Eye Loupe for GIA Use and Quick Identification Gemstone Jewelry Magnifier - Image 2](https://m.media-amazon.com/images/I/71t9mX5OMAL.jpg) ![TEKCOPLUS Handheld Diffraction Spectroscope, Pocket-Sized Grating Gemological Spectrometer in a Gem Tool Jewelers Eye Loupe for GIA Use and Quick Identification Gemstone Jewelry Magnifier - Image 3](https://m.media-amazon.com/images/I/71QlEkWEqgL.jpg) ![TEKCOPLUS Handheld Diffraction Spectroscope, Pocket-Sized Grating Gemological Spectrometer in a Gem Tool Jewelers Eye Loupe for GIA Use and Quick Identification Gemstone Jewelry Magnifier - Image 4](https://m.media-amazon.com/images/I/71gzkZ6Cy0L.jpg) ![TEKCOPLUS Handheld Diffraction Spectroscope, Pocket-Sized Grating Gemological Spectrometer in a Gem Tool Jewelers Eye Loupe for GIA Use and Quick Identification Gemstone Jewelry Magnifier - Image 5](https://m.media-amazon.com/images/I/51eXN1fzNXL.jpg) ## Available Options This product comes in different **Color** options. ## 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. ## Customer Reviews ### ⭐⭐⭐ For an immediate undertanding of how light is formed *by J***N on 26 April 2017* For an immediate undertanding of how light is formed.
