💎 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.
💎 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.
💎 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.)
💎 NOTICE: * No matter what gemstone you are testing, the probe needle and the tested object must be at a 90° angle. * When testing diamond, your right index finger must keep touching the metal panel on the back of the tester, while you do not touch the panel if you test other gemstones. * Do Not test any metal. * Do Not wear glove.
💎 Product size: Size: 3.7cm ×3.5cm ×1.5cm /1.46 *1.38 * 0.59inch (L*W*H). Power needed: 1x 9V battery (not included). If you have any problem about the testing, please contact us, we would love to help.

Product: Mohs Hardness Test Kit Mohs Hardness Picks 5 Pack Mohs Hardness Tester Industrial Mineral Identification Kit Gem Jade Jewelry 5-9 Scratch Tester
Brand: Saladulce
Description: Introduction of hardness pen
The hardness of a gemstone refers to the ability of the gemstone to resist scoring, pressing and grinding of foreign objects.
The hardness of a gemstone is an important factor determining the value of the gemstone.
When two minerals with different hardnesses scratch each other, they will leave scratches on the surface of the minerals with lower hardness.
Physical scratch test
This method is based on the comparison between the engraved gemstone minerals and the standard hardness minerals.
The hardness difference between two adjacent standard minerals is different.
The difference between corundum and diamond is large.
The Mohs hardness pen is 5 # apatite, # 6 orthoclase, 7 # quartz, # 8 Topaz # 9 corundum
in the Mohs hardness tester set on five heel metal rods respectively.
Use the edges and corners of these ore to score the sample to be tested.
According to whether there are scratches on the sample to determine the hardness of the sample:
If scratches are left, it means that the hardness of the sample is lower than the hardness of the hardness pen.
If it cannot be moved, the hardness of the sample is higher than the hardness of the hardness pen.
Model: 5#--9# Mohs hardness
Size: pen 100x6mm; box 150x100mm
Material: pen point(5 # Apatite; 6 # Orthoclase; 7 # Quartz; 8 # Topaz; 9 # Corundum)

Product: Presidium Instruments Gem Tester II (PGT II) with Assisted Thermal Calibration (ATC) for Identifying Diamonds/Moissanites and Common Colored Gemstones
Brand: Presidium
Color: Black
Description: AN INDUSTRY LEADER

The Presidium Gem Tester II is based on the invention of Professor Julian Goldsmid from the University of New South Wales in Australia. It was developed to distinguish between diamonds and its other simulants using the principles of thermal conductivity.

The Presidium Gem Tester II with Assisted Thermal Calibration provides a quick and easy way to identify diamonds/moissanites and separates up to 16 common colored gemstones based on their thermal conductivity with its clear and direct analog display.

NEW INCLUDED CALIBRATION FEATURE

As PGT II works on the thermal conductivity of the gemstone, its measurement will be affected by the testing environment. WIth the improved function of Assisted Thermal Calibration (ATC), the user is now able to easily calibrate the tester according to the testing environment for a reliable and consistent reading.

The Presidium Gem Tester II Features:

Retractable thermoelectric probe tip that ensures constant pressure between probe tip and gemstone
Industry's thinnest probe tip (0.6mm) for testing diamonds as small as 0.02ct
Metal alert buzzer to ensure that probe tip is in contact with gemstone during testing
Clear and easy-to-read analog dial
No waiting time between tests
Built-in Calibration (CAL) and Glass test discs for reference
Powered by 2 x AA batteries or adaptor
