Rare Eudialyte Gemstone Pendant
The deep-red colour in this cabochon is the rare mineral eudialyte.
The deposit in Southern Greenland where eudialyte was discovered contains many rare earth elements, all of which are present in the mineral eudialyte.
Eudialyte, which has a complex structure, is composed of sodium, zirconium, and silicon, with a mix of other elements, including calcium, iron, and manganese.
Even though this eudialyte cabochon is quite dark, it's finely polished, so it reflects from almost every angle.
