Very rare arctite with podlesnoite in natrolite/albite! The rare fluorescent mineral arctite (Na₂Ca₄(PO₄)₃F) fluoresces bright bluish white under LW lighting and normally occurs as small grains. In this recent last find, the crystals are much larger in the specimens found! Arctite is less bright under MW light and non-fluorescent under SW. Fluorapatite is the most common fluorescent mineral in these specimens. It is moderately bright in MW light, less bright in SW, and non-fluorescent in LW. It has a violet color in MW and SW. The other identifiable fluorescent mineral is albite. Albite fluoresces dull red in SW light. The specimens also contain non-fluorescent black aegirine and brown lamprophyllite. Guaranteed that no one else is offering this at the moment. Difficult to obtain, directly from Russia, and this was the last material dugged out... Long wave/UV 365 nm (arctite is blue) Medium wave/UV 310 nm (arctite is blue, podlesnoite is pink) Short wave/UV 254 nm (podlesnoite and albite is pink) Accompanying text translated: "They found (2026) a narrow vein measuring 1 by 1 meter. Arctite usually occurs in small grains measuring a few millimeters in size. The amount of arctite that a gold prospector can extract is the same. Podlesnoiet and arctite are possibly the only minerals of this type on Earth. Arctite occurs only in the Khibiny Mountains and nowhere else in the world. The remaining part of the vein collapsed after the explosions and was subjected to apatite ore mining."
