{"product_id":"ilgi-7209","title":"ILGI-7209 Foldaway Dichroscope Gemstone Jewelry Testing Tool Lightweight and Portable Ideal for Jewelers and Gemologists","description":"\u003cp\u003eThis foldaway design dichroscope is a specialized tool for observing pleochroism in birefringent gemstones. It works with single crystals that are transparent, semi-transparent, and colored. To use, ensure the gemstone sample is illuminated by white light sources, such as natural daylight or incandescent lamps, avoiding monochromatic light. Maintain a viewing distance of 2-5 cm between your eyes, the dichroscope, and the sample. Rotate the gemstone or dichroscope 360 degrees during observation, noting trichroism from multiple directions. Distinguish between true dichroism and color bands, as two observed colors in the same direction often indicate color banding rather than pleochroism.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eFeatures:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan class=\"a-text-bold\"\u003eClear lens\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-text-bold\"\u003eFoldable design\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"a-text-bold\"\u003eCompact and portable\u003cbr\u003e\u003c\/span\u003e\u003cspan class=\"a-text-bold\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-text-bold\"\u003eUses white light sources such as natural light and incandescent lamps\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-text-bold\"\u003e2-5cm distance between the dichroscope and the gemstone during the inspection, moving 360° until you can observe the trichroism from multiple directions\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eSpecifications:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eItem Type: Dichroscope\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMaterial: Durable metal housing\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eLens Diameter: \u003c\/span\u003e\u003cspan class=\"a-text-bold\"\u003e2cm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eColor: White or Black\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSet Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e1 x Dichroscope\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e1 x Synthetic Leather Case\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eStandard Factory Packaging\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"F01","offers":[{"title":"Black","offer_id":43067237793835,"sku":"ILGI-7209_BLK","price":35.9,"currency_code":"USD","in_stock":true},{"title":"White","offer_id":43067237826603,"sku":"ILGI-7209_WHT","price":35.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/5850\/1675\/files\/gain-express-clmg-7209-blk-clmg-7209-foldaway-dichroscope-gemstone-jewelry-testing-tool-lightweight-and-portable-ideal-for-jewelers-and-gemologists-204087.jpg?v=1770633156","url":"https:\/\/instrulife.com\/products\/ilgi-7209","provider":"Instrulife","version":"1.0","type":"link"}
