Case it pretty good too. ### ⭐⭐⭐⭐ Awesome! *by on Reviewed in the United Arab Emirates 13 August 2023* The product is good with LED and UV lights.Magnifying is also great, you can see the details the smallest details. I can recommend it. ### ⭐⭐⭐⭐⭐ Ideal for Geology, Petrology and Mineralogy *by on Reviewed in the United Kingdom 31 March 2025* This lens has impressive optics. Images are very clear allowing fine details to be seen. The field of view at 21 mm is excellent, enabling a large area to be viewed. It is good for viewing the details of crystals in a rock or individual mineral crystals. Attached photos show a flat polished piece of quartz-microgabbro and a group of grossular garnets. Also a photo of a millimetre ruler plus detail of the same photo. Taken with a phone camera they are not quite as good as what you can see with your eye because when you are using it you make minor position adjustments to view different areas.The white LED light is very useful when there is insufficient light available, although you do get some reflection off shiny surfaces. It should be ideal in shaded spots such as dense forests or on a very dull day. The long wave UV light works fine. It was good to see some calcite crystals glowing pink. As the light is also visible (i.e. not a black light) it is not the same as using far more expensive UV lighting.Construction is excellent with just the right stiffness in the hinge. It has a smart leather case for storage and there is a slot at the top for attachment of a lanyard. ## Frequently Bought Together - Gain Express Jewelers Loupe Magnifier, Jewelry Loop Magnifier with Light, Hastings Triplet Loupe 10X for Coin, Gem, Stamp, Diamond etc (White LED & UV Light) - 40X Full Metal Illuminated Jewelry Loop Magnifier, XYK Pocket Folding Magnifying Glass Jewelers Eye Loupe with LED(LED Currency Detecting/Jewelry Identifying) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/253178975-gain-express-10-x-21mm-mini-folding-illuminated-loupe-jewelry](https://www.desertcart.com.ar/products/253178975-gain-express-10-x-21mm-mini-folding-illuminated-loupe-jewelry) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-05*
