5 thoughts on “Does anyone know how many times the magnifying glass for jade?”

In gemstones, a 10 -fold mirror is generally selected (represented by "10 ×"), which is the most commonly used in three combined mirrors. Formed. In the national standard, there are clear standards for some jewelry, jade and antiques, and the conditions are "under ten times under the mirror." The working distance between the magnifying glass and the sample of the inspection depends on the magnification, the magnification is large, the smaller the working distance, the inconvenient operation, and the vision range is also reduced. This is another reason why the gemstone is choosing to use the 10 × magnifying glass. The characteristics of gemstone magnifying glass: wide vision, eliminating image distortion and scattering, that is, non -image difference and color difference.

1, gem surface feature observation (1) the gloss of gems Different gloss indicates that it may be a combined stone; different gem varieties have their characteristic luster, such as diamonds are diamond luster, colorless rigida jade is glass luster. (2) The sharpness of the gem aspect is sharp . The face of the gem is sharp and straight, which indicates that its hardness is high. For example, the face of the diamond is always sharp and straight, while the imitation diamond is smooth. (3) The original crystal, clearing, and fracture of the gem If the surface of the surface of the surface, the person with a step -shaped section shows its explanation and development It may be a single crystal gemstone or glass imitation; those with soil and granular fractures indicate that it may be a multi -quality collection; the original crystal surface of the bitter gemstone, indicating that it is a natural gemstone. (4) Gem cutting quality and polishing quality Observe whether the ratio of the gem is appropriate, whether the ratio and symmetry are intact, and whether the various small asymmetry is symmetrical. How is the surface of the gemstone, whether it leaves polished marks, burning gangrene, etc. (5) Surface defects of gem Observe whether there is damage, scratches, concave pits, cracks, etc. on the surface of the gemstone. 2, observation of the characteristics inside the gem (1) Ribbon, growth pattern Ifins to see the straps bent, indicating that it is an qualified product. Such as synthetic sapphire. (2) Face -to -face edge shadow If see the face -to -face edges, it indicates that it is a gem with a large double refractive index. Such as microcyllastone, gangsters, etc. (3) Packal Ifins if you see mineral parcels, indicate that it is a natural gem; if you see a bubble, it indicates that it is an artificial gem. You can also provide gemstone producing information according to the characteristics of the wrap combination observed. Such as Sri Lanka's emeralds with qi, liquid, and solid three -phase parcel.

Ordinary use of jade amplification mirror multiples are generally about 10 times. If you want to see more thinner, it is less than 30 times. To be honest, the domestic magnifying glass manufacturer is 10 times the bid, generally about 7-8 times, and the smaller ones are 10 times the bid at 5-6 times. The export -type product multiple is more accurate. Good luck!

The upstairs is right, using a set of lens magnitude (2 ~ 4 pieces), the multiple is more than 20 times.
10 times is a general standard
