- This gemstone testing equipment is not only a diamond tester, but also a multi gemstone tester. It can detect if a gemstone is real or fake, including: diamond, sapphire, ruby, crystal, agate, jadeite, and other precious stone of various sizes.

- Before Test: 1. Put the battery in the tester. 2. Take off the probe cap. 3. Turn on the switch. 4. Make sure only one light light up on the scale. 5. Make sure the " ready lamp" light on. 6. (If test diamond, you then need to turn on the lights number corresponding to the indoor temperature and diamond weight.). 7. (If test other gems, you'd better calibrate the probe, method: by placing the probe vertically on a glass, then adjusting the light to 5, then test the gems.)
- * If the number of lights equals or exceeds 9, and it beeps, it means the diamond is true. * If the lights is about 9 and it beeps, it means the sapphire is true. * If the number is 6.5-7, it means the agate is true. * If the number is 7-8 , it means the crystal is true. * If the number is 6-7, it means the jade is true.

Hqdz-tdDiamond Tester Pen, Jewelry Diamond Tester with 60X Mini LED Magnifying&40X Full Metal Illuminated Jewelry Loop Magnifier, Thermal Conductivity Meter, Diamond Selector for Novice and Expert
Main highlights- ●It is designed for quick, precise, and safe diamond testing. ▲【Professional Diamond Selector】 After powering on, turn the wheel to keep 4 green lights on to finish the Initialization. Otherwise you will get inaccurate results.For Diamond Simulants：No Sound and No Red lamps light on.[Note]: This diamond tester cannot distinguish Mosanite and diamonds. Because the product works by measuring the thermal conductivity of an object. The thermal conductivity of Mosanite is almost the same as diamond.
- ▲【Intuitive Design】Our diamond tester features an LCD display and LED indicator make it easy to read your precise testing results. No need for a professional - the Hqdz-td Diamond Tester Pen is easy to operate. Just turn it on, lightly press the tip to the gemstone, and wait for the beep to know if it's real or fake.
- ▲【For Metal Alert】When Testing metal, it will emits beeping-beeping-beeping in a high frequency,5times/second. The thermal conductivity of the metal is very high and can give the same indication as a diamond with most thermal probes.This Diamond Selector II has a metal Alert Buzzer to warn you when touches metal. If you hear the Metal Alert buzzing sound,re-touch the probe tip so as to touch only the tested stone.Other Alert：When test other items, it will also emits beeping-beeping-beeping in a high frequency,5times/second,such as your body,water,and so on.
- ▲【For Imitation】When Testing Imitation stone,such as cubic zirconium ( CZ ), crystal, glass, there will be no sound, and the red lamp won’t light.This diamond tester II can just distinguish diamond and fake diamond,but CAN NOT distinguish Moissanite & Real Diamonds。For testing diamond, it will emits beeping-beeping-beeping in a low frequency, 1 time/second. Meanwhile 1-4 pieces of the RED LAMP box of the level meter light on(the bigger the size of the stone is, the more pieces of the red lamp box of the level meter light up)
- ▲【Bright LED】With this dual LED light source, you can clearly see objects in the dark or in low light. The magnifying glass provides a detector for detecting counterfeit banknotes, which is used for banknotes, passports, credit cards and traveler's checks, etc.It is very convenient to carry and you can use it anywhere.
