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: Rare Earth N52 Neodymium Pocket Keychain Gold & Silver Jewelry Test Magnet
Brand: Highlandhawker
Color: Gold
Description: Comes with a split ring for easy carrying, and a protective vinyl cap. The magnet insert is rated at 10 lbs (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface). These magnets have an excellent feel and are very sensitive. It is the perfect size and strength for identifying fake silver and gold jewelry! The brass casing protects the magnet from chipping and breaking. Dimensions are: 1/2" diameter x 3/4" tall head, 2-1/2" overall length, 3/8" diameter handle, 1/2" diameter stainless steel split ring. Please note: A strong magnet helps in evaluating and identifying fake jewelry, but it is not fool proof. Instructions: Jewelry: The magnet should always be the first test you perform on an unknown piece of jewelry. If there is any steel or iron present, the magnet will attract. These metals are found in jewelry where they are electroplated with gold or silver, but they will never be present in high quality jewelry (with the possible exception of clasps, which sometimes have steel springs inside them). It is important to note, however, that not all fake jewelry will have these metals present because there are other non-magnetic metals that can be used as a base. Anything that passes a magnet test (no reaction from the magnet) can be scrutinized further. Proudly made in the USA!
Ideal for metal recyclers, brokers, antique buyers and collectors!
