Moonstone identification

Moonstone, in fact, is the "moonstone guide" in the gemology (the name of the mineralogy called "micro-inclined feldspar") is called because of the "moonlight effect" (the blue or bright white halo of the moonlight appears in the center of the gem) Moonstone. There are many gemstones that have a moonlight effect in nature, but they can only be called moonstones when the feldspar minerals have this effect. Other gemstones cannot use the moonstone name even if they have a moonlight effect. So, what are the key points for the identification of moonstone?

The gems similar to the moonstone are mainly white quartz cat's eye, chalcedony, white opal, glass and plastic. The important difference between moonstone and them is:

1. Moonlight's fainting is extremely special. When turning a gemstone, it tends to move in a sheet shape, while the quartz cat's eye shows a linear movement of the eyeliner.

2. Feldspar has obvious texture, and there are jagged fractures in some small sections, while other similar gemstones are mostly shell-shaped fractures, and the fractures are smooth curved surfaces.

3. Inside the moonstone, there are sometimes “100-footed” inclusions, which can be used as an important basis for identification. When the above characteristics are not obvious, it is determined by measuring the refractive index and specific gravity of the gemstone. Identify key typical cleavage, feature inclusions.

4. The blue of the moonstone is very crystal clear, and the transparency of the moonstone is also very high. The good quality moonstone will be translucent, and the moonlight will be in the middle.

The method of identification of moonstone is based on the unique color, transparency, gloss, hardness, specific gravity, inclusion, dispersion, cleavage, fracture, birefringence, special optical effects, etc. of the gemstone, using simple tools such as 10 times or more. Magnifying glass, spotlight flashlight, etc. are identified.

The gems similar to the moonstone are mainly white quartz cat's eye, chalcedony, white opal, glass and plastic. The important difference between moonstone and them is that the fainting of the glaciers in January is extremely special. When rolling a gemstone, it tends to move in a sheet shape, while the quartz cat's eye shows a linear movement of the eyeliner. 2 Feldspar has significant cleavage, and there are jagged fractures in some small sections, while other similar gemstones are mostly shell-shaped fractures, and the fractures are smooth curved surfaces. In March, there are sometimes "100" insects in the interior of the light stone, which can be used as an important basis for identification.

Aramid fiber fabric

Aramid fiber fabric is a type of synthetic fabric made from aramid fibers. Aramid fibers are a class of heat-resistant and strong synthetic fibers that are used in a variety of applications, including aerospace, military, and industrial applications. The most common types of aramid fibers used in fabric production are Kevlar and Nomex.
