Designed for use by jewellers, gem traders, or serious collectors, the device provides an immediate on-site test that complements visual inspection. Its operation is based on measuring how efficiently heat passes through a material, a key physical property that differs between diamond and common simulants. With clear visual indicators and an audible signal, the tester delivers a straightforward result you can act upon, whether you're in a shop, at a trade show, or examining a personal collection.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Second generation black diamond thermal conductivity tester with metal probe for gem identification\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/718\/2025-10-02\/original-image\/2009607269177.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe tester's design prioritises portability and straightforward operation for its specific application in gem identification. Its construction and features are tailored to deliver a reliable test result in a compact format suitable for various settings.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe device is built using a combination of metal and engineering plastic. The metal components are critical for the test's function, forming the probe that contacts the gem and the rear plate that contacts your finger to complete the circuit. The engineering plastic housing encases the electronics and contributes to the overall light weight of 66 grams. This material choice makes the unit durable enough for regular handheld use while keeping it easy to carry.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eWith dimensions of 135 mm in length, 40 mm in width, and 23 mm in thickness, the tester is designed to fit comfortably in the hand. Its slim profile and lightweight nature mean it can be easily stored in a toolkit, desk drawer, or even a coat pocket. The 9V battery power supply eliminates the need for mains electricity, allowing for testing anywhere. The black colour provides a neutral, professional appearance suitable for both shop and field use.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Second generation black diamond thermal conductivity tester with metal probe for gem identification\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/718\/2025-10-02\/original-image\/27217276117895.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe primary and stated application for this instrument is diamond identification, with an additional mention of gem hardness testing. Its portability opens up several practical scenarios where immediate verification is valuable.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor jewellery professionals, pawnbrokers, or gem traders, this tool serves as a first-line verification device. It can be used on the shop floor to quickly confirm a diamond's authenticity for a customer or when evaluating an item offered for sale. At trade fairs or auctions, its battery-powered operation allows for discreet checking of stones without needing access to a power outlet. The clear pass\/fail signal—10 lit LEDs and a beep—provides an unambiguous result that can inform a buying, selling, or valuation decision.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the private collector or individual assessing inherited or previously owned jewellery, the tester offers a way to gain confidence about a stone's identity without immediately resorting to costly laboratory services. Its simple operation, requiring only contact between the probe, the gem, and your finger, makes it accessible for occasional use. The device can help organise a collection by confirming which pieces contain real diamonds, aiding in insurance documentation or simply providing personal certainty.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Second generation black diamond thermal conductivity tester with metal probe for gem identification\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/718\/2025-10-02\/original-image\/338793471808.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of this thermal conductivity tester lies in its specific function, portability, and the practical clarity of its results. It addresses a particular need for on-the-spot gem verification.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eAs a durable electronic tool, the tester is designed for repeated use over time. Maintenance is minimal, primarily involving battery replacement for the 9V power cell. The sturdy metal and plastic construction suggests it can withstand the handling typical of a workshop or retail environment. Its singular, focused purpose means it will remain a relevant tool for as long as thermal conductivity remains a key test for diamond identification.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis second generation model represents an iteration likely aimed at refining the user experience from a previous version. The choice for a user comes down to needing a dedicated, portable instrument for this specific test. Compared to more complex lab equipment, it offers speed and location flexibility. Compared to purely visual or scratch tests, it provides a result based on a measurable physical property. For anyone regularly needing to distinguish diamond from common simulants like cubic zirconia or moissanite in a non-lab setting, this tool fills a clear and practical gap.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Second generation black diamond thermal conductivity tester with metal probe for gem identification\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/718\/2025-10-02\/original-image\/4718715954017.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Second generation black diamond thermal conductivity tester with metal probe for gem identification\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/718\/2025-10-02\/original-image\/480137019940.webp\"\u003e\u003c\/div\u003e","brand":"test232qr7fty34e78gef","offers":[{"title":"Black","offer_id":52963043672400,"sku":"CJXFZNZN00565-Black","price":28.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/0791\/9952\/files\/2009607269177.webp?v=1777557836","url":"https:\/\/rdb0xc-e7.myshopify.com\/products\/diamond-thermal-conductivity-tester-for-gem-identification-second-generation-black-metal-and-engineering-plastic-construction-135x40x23-mm-portable-size-66g-lightweight-battery-powered-device-for-hardness-testing","provider":"Novea.com","version":"1.0","type":"link"}
