High Accuracy Diamond Tester Professional Jeweler For Novice and Expert - Diamond Selector II 9V Battery Included

Product Information

Thermal conductivity diamond testers measure the amount and speed that heat travels through the stone. It carries out the diamond test (see above) then, a fraction of a second later, it carries out the Moissanite test (see above) and its microchip combines both readings and calculates a response. use the downloadable software (from Presidium), each test will display data on the computer listing many variables (in addition to refractive index) that will help you identify the stone. Additional gems besides diamonds have high conductivity (such as moissanite) but a diamond tester can separate a diamond from a cubic zirconia. The disadvantage is that it is a sophisticated piece of laboratory equipment which needs to be used with great care.

works on any stone, you are not limited to jewellery that will fit over the sensor, you are not limited to transparent stones with a flat top (table), they even work on 'rough' (uncut) stones. Harness the power of knowledge with the industry-leading instruments that GIA uses in its grading laboratories. These instruments have proven accurate and reliable through extensive use by experts, students and retailers alike. If you are working in an office where you can sit comfortably at a desk and work slowly and carefully, then get a reflectivity/Refractive Index gem tester as listed below. Empowered by our instruments, GIA remains at the forefront of technology and ready to take on technological disruptions, such as new treatments and laboratory-grown gemstones.Watch the video to learn about the BELIZE, developed by one of the best diamond tester manufacturers. Diamond testers can be a helpful tool as part of a multi-stage test to determine if a diamond is authentic, but it should not be the only test. Their natural diamond testers are very accurate and reliable, but it requires some practice and learning before our staff can use it properly. The latest diamond testing devices combine heat and electricity testing so they’re the most accurate. In addition to diamond testing devices, there are at-home tests you can do to check the authenticity of natural and raw diamonds including the sandpaper test, read-through test, sparkle, water, and heat tests.

Gemlogis was co-founded by a gemmological precision engineer who brought early influence to the handheld diamond tester machine two decades ago. By contrast, a large ruby or sapphire will move the LED segments up slowly, and other (very large) stones may or may not produce any reaction at all. The GIA iD100 can test colorless to near-colorless, green-to-blue and brown diamonds, as well as pink diamonds when used with the GIA iD100 Pink Diamond Software Upgrade. Gemlogis is a leading diamond tester manufacturer with aspirations to develop the best diamond testing machines for users across the globe.Although synthetic diamonds have the same crystal structure and chemical composition as natural ones and pass a diamond tester, the diamond growing process leaves unique features in the finished products. you have been given a parcel of stones and want to pull out those that are 'interesting' and worthy of further investigation.

They get their color from large quantities or clouds of mineral inclusions (graphite, pyrite or hematite) in the stone.Depending on the principle the tester utilizes, there are devices that measure the thermal conductivity or electrical conductivity of the stone and multi-testers that combine both methods. Stones must be Brilliant Cut (modern, round) and perfectly-cut in proportion, it will not test shallow stones. This is important because metal will register as diamond on most diamond testers that lack the metal detector feature. if you understand the limitations of gem testers but there really is no way you have time to keep the tester meticulously clean and clean every stone before every test, and you cannot guarantee that it will never be bumped or dropped or get dusty or damp. not as accurate as an optical refractometer, it's possible (as with all electronic testers) for the display to 'drift' and not give correct readings.

Now maybe (I didn't ask) the stone had been in the family for generations and was 'very valuable' - but I do suspect that it wasn't diamond. It is for showing you the chance of a diamond being natural (originating from the earth) or synthetic (manmade in a laboratory) - both are 'real' diamond. It is also particularly easy and fast to use and can be used on any stone no matter how it might be mounted.This enables them to design instruments that are efficient, user-friendly and that will last for years to come. Reflectivity / Refractive Index testers are optical not thermal (so they work at any temperature), they help identify many dozens of stones. Strangely, it would not register DIAMOND on a diamond tester at a local jewellers (a totally different model of tester). Technology is advancing, and there are many accurate models on the market; however, to choose the best diamond tester, you may want to consider some aspects. For the professional jeweller: if you specialise in Victorian jewellery (or earlier) this tester might not be suitable, it will not give accurate results on rose-cut etc.
