2. It is mainly a compact block composed of jadeite minerals. Under the microscope, jadeite minerals that make up jadeite are closely intertwined, forming a fibrous structure of jadeite. This compact fiber structure makes jadeite delicate and tough.
3. Jadeite is a mineral aggregate composed of a variety of fine minerals, mainly jadeite. Its main mineral is jadeite, and its secondary minerals are omphacite, sodalite, albite, amphibole, tremolite, diopside, aegirine, aegirine, zeolite, chromite, magnetite, hematite and limonite.
Mineralogically speaking, jadeite is a kind of rock, which is composed of many tiny minerals. These small minerals are jadeite naal [Si2O3], sodalite nacr [Si2O3] and aegirine nafe [Si2O3]. These three main minerals exist in different proportions and are called "isomorphism" in mineralogy.
5. Heterogeneous aggregates, that is, the optical characteristics of jadeite, that is, mineralogical characteristics. Distinguish the authenticity of the jade identification certificate: first, carefully look at whether the issuing institution that issued the jade jewelry inspection certificate has the right to issue the jade identification certificate.
