2.9" Polished Red-Pink Yuksporite - Yukspor Mountain, Russia

This is a 2.9" wide, polished yuksporite section that was collected from Yukspor Mountain on the Kola Peninsula of Russia. The specimen features sprays of red-pink yuksporite crystals that are associated with an array of other minerals. Under shortwave UV, the yuksporite fluoresces a mixture of white, yellow and orange, with vibrant red fluorescence of what is likely calcite adjacent to the yuksporite.

One side of this specimen has been polished to a glossy finish, while the rest has been left in its rough state. Comes with an acrylic display stand.

Yuksporite is a rare inosilicate mineral that often bears brown-pink, rose-pink to yellow coloration. The type locality of Yuksporite is Hackman Valley on Yukspor Mountain, where the first documented discovery was by Ekaterina Evtikhievna Kostyleva in 1922. It has quite a complex chemical formula - K4(Ca,Na)14Sr2Mn(Ti,Nb)4(O,OH)4(Si6O17)2(Si2O7)3(H2O,OH)3 - and contains rare elements such as niobium, strontium and titanium, among a wide variety of other more common elements. Yuksporite is only known to be found in Russia where it occurs in veins in nepheline syenite.
