👉 Which is rare montebrasite or fluorine dominant amblygonite?

  • Amblygonite and montebrasite form a mineral series. Fluorine-dominant (F) amblygonites are much rarer than hydroxyl-dominant (OH) montebrasites. In addition, amblygonite has a biaxial (-) optic sign, while montebrasite has a biaxial (+) optic sign. Many gems labelled as amblygonites in collections may merit reexamination.

👉 Which is the mn dominant composition of rhodonite?

  • A pure Mn-dominant rhodonite is better expressed as Mn2+Mn2+3Mn2+[Si5O15], and indeed in 2019 this composition was recognized as the new rhodonite group end-member vittinkiite. The 5 cation sites exhibit ordering, that have given rise to such species as ferrorhodonite, which requires M5 to be Ca-dominant and M4 to be Fe2+-dominant.
