GEMTRUE APEX SYNTHETIC DIAMOND TESTER DK10300 - TD10300

The APEX is a combined standard (thermal) tester for diamond / non-diamond, plus the latest-technology (UV-absorption) to distinguish natural diamond from synthetic diamond. Plus it tests for Moissanite and Cz/Simulant (= any other stone). One probe, one test, the onboard computer works out the answer.

• Handheld, lightweight.
• Can test any stone mounted in jewellery and it also comes with a stone-holder for testing loose stones.
• If diamond, it tells you the chance of that diamond being natural or synthetic
• Fastest response (test-result in 1 or 2 3 seconds)
• USB rechargeable battery
• One year guarantee

The Apex tests for the following:

Natural diamonds. These grow as crystals deep in the Earth (they take 2 to 3 billion years to grow), they are also known as mined diamonds.

Synthetic diamonds. These are grown by man in a laboratory (they take a few weeks to grow). Also known as lab-grown, manmade or lab-created. The APEX tests for both types (manufacturing techniques) of synthetic diamond, CVD and HPHT.

Synthetics and naturals are identical, they are both diamond. They are the same chemically, they are the same optically. That is why it is so difficult to tell them apart.

Moissanite. A synthetic stone only (it doesn't exist in nature as crystals that can be cut into gemstones). This is the one stone that looks like diamond, even to an expert.

Size 105mm X 70mm X 25mm

Operating temperature: 10° to 35°C

Size, must be a minimum of 5pts (0.05 carat) = table (top) diameter at least 2.5mm.

Power: built-in rechargeable batteries, USB charging (5V, minimum 0.5A) cable supplied. Does not support PD fast charging. LED bar indicates amount of power remaining, when it reaches RED you must charge it, otherwise you will get incorrect readings.

Auto-power-off yes, if used on battery power it turns itself off after 5mns of non-activity.

Cz or Simulant. A "Cz" or "Simulant" readings indicate that the stone is not diamond. This is not 'diagnostic', ie it won't tell you what the stone is, the APEX is not a gem tester, it is a tester for natural diamonds / synthetic diamonds / Moissanite.
