Nitecore GEM8 Gemstone Identification LED Torch

£59.94

The Nitecore GEM8 is a professional gemstone identifier with infinitely variable brightness white light between 500 lumens and 1 lumen from a Cree XP-L HI V3 LED.

The GEM8 is best used for small gemstone inspection due to the narrow head design in which the LED is attached directly to the lens to ensure zero light loss, ideal for identifying small item such as Jade beads, diamond ring, crystal beads etc. The side of the torch has an integrated measurement scale so you can easily measure the size of the gemstone.

This special design has a better beam focus, with the convergent light ensuring a clear inspection and the flat top of the GEM8 allows for close observation without scratching the item. The LED allows for great penetrability of the gem to identify the texture, technique, flaw or crack of gemstones and is great for identifying impurities of Jades.

The rotary switch is turned clockwise until a click is heard and the light come on at the lowest point and can be gradually made brighter by continuing to rotate the switch, allowing you to select the best output depending on the size of the gemstone. Turn the switch back anti-clockwise until a click is heard to turn the light off again.

Powered by two CR123A lithium metal non-rechargeable batteries or one 18650 lithium-ion rechargeable battery (not included). Advanced temperature regulation allows the GEM8 to regulate its output and adapt to the ambient environment to maintain optimal performance.

Product Features

Rotary switch allows infinite brightness
High efficiency constant circuit
Tail stand capability
Advanced temperature regulation

Operational Modes

Turbo: 500 lumens; 1 hour run-time
Ultralow: 1 lumens; 500 hours run-time

Please note: Advanced temperature regulation technology allows the GEM8 to dynamically adjust the output performance according to it's temperature to prevent damaged from over heating. The turbo run-time is tested without the advanced temperature regulation, therefore results may vary between torch, battery and environment.

Tested to ANSI/NEMA FL1 standards in laboratory conditions using 1 x Nitecore 18650 3500 mAh lithium-ion battery.

Nitecore GEM8 Gemstone torch - a gem of a torch & more

- Fast delivery. Classic Nitecore box, bits & bobs. I popped in a couple of Duracell Lithium 123 batteries and we are up & running. A very smart looking design. Simplicity itself to use, as befits a dedicated tool-torch.- My point in writing a review is this. I'm not a jeweller and I have no interest in gemstones. So why buy a 'Gemstone' torch? Answer: I repair vintage fountain pens... and this torch, with it's distinctive narrow 'nose' and variable light intensity is perfect for inspecting old fountain pens for hairline cracks. That extended lens 'nose' fits neatly into the open end of a plastic / cellulose fountain pen cap or barrel, illuminating the INSIDE in a blaze of light that reveals the the tiniest of imperfections to the observer looking at the OUTSIDE of the pen. It does not matter if the plastic is not obviously transluscent. By the time you've dialled this torch up to 500 lumens, it will be. Brilliant torch (forgive the pun) that has utility well beyond it's 'Gemsone' moniker. Aside: There is a handy 8cm scale included in a flattened elevation of the barrel that also stops the torch rolling off a flat surface. A nice touch.
