Product｜Model quality｜High-quality hymenite is produced at the foot of Gilimanjaro Mountain in Tanzania, Africa. It is also the only place where the famous tanzanite is produced. Although the two are different minerals, in terms of color, if you can buy a hyalurite that is very similar to tanzanite, it means that the quality of the hyalurite is very good! But if the jadeite is violet, or has no color-changing ability, or the gemstone crystal is cloudy, or opaque... If there is nothing similar to tanzanite, then it is of inferior quality or even not jadeite. High-quality hyalurite is actually not very common. Due to its physical properties, the longitudinal axis will have an extremely strong cleavage. Therefore, lathes need to be polished by lathes, which is a problem for lathes who do not have solid qualifications and do not have a deep understanding of the properties of gemstones. It is very easy to break the mosaic. Coelite has the above-mentioned set of obvious cleavage characteristics, so it is extremely necessary to prevent the gemstone from falling, and any falling is prohibited. The Mohs hardness of 7.5 means that it has high scratch resistance. Tourmaline and garnet cannot scratch heelite, but this does not mean it is collision-proof!
