Beryllonite is a mineral with a hardness of 6 out of 10 on the Mohs scale of mineral hardness [?]. These Monoclinicly structured gems are made of sodium beryllium phosphate, their full chemical compound being NaBePO4.

Beryllonite is a clear gem/mineral that gets its name from its high content of beryllium. There are very few gem quality pieces that have been produced.

Beryllonite can be found in Pakistan, Brazil, Finland, and Maine. It has a color streak of white, and a vitreous luster.

The specific gravity [?] for Beryllonite is 2.83, it's refractive index [?] is 1.55-1.56, and it's double refraction [?] is 0.009.

Double Refraction or dr is the ability of a mineral to separate a refracted ray of light into 2 rays. If held over an image or text it will display the object 2x its original size.

Mohs Scale of Mineral Hardness is the standard used to categorize a mineral's ability to resist scratching. It gets its name from Friedrich Mohs, the German geologist who first created the scale.

RI or Refractive Index defines light's ability to move through the mineral or in a general sense, any material.

SG or Specific Gravity is the ratio of the weight of any substance to that of pure water at temperature of 3.98°C(39.2°F) and standard atmospheric pressure. This is important to note when actively seeking these minerals in the wild. Minerals with a higher SG will settle below material with a lower sg over time.
