Kovdorskite
Kovdorskite is definitely a rare phosphate mineral that is hardly ever available being a gem that is faceted. The formula of Kovdorskite is Mg5(PO4)2(CO3)(OH)2 · 3(H2O) (Hydrated Magnesium Phosphate Carbonate Hydroxide) and its molecular weight is 486.56 gm. Specific Gravity of Kovdorskite is 2.28 (g/cm3). It is found at one location: the Kovdor Massif, Kola Peninsula, Murmanskaja Oblast’, Northern area, Russia. This locality is host to an inventory that is long of and obscure minerals, many of that are unique to your locality. Kovdorskite is an extremely mineral that is attractive well-formed crystals of pale blue or pale pink. Some crystals are blue with even pink terminations.
