Excellent specimen of dull grey Paakkonenite as the matrix hosting good sprays of Kermesite. There are also numerous crystals of which I have never seen before, but are probably apatite of valentinite. They are striated and tapering and very unusual in form.

Nearly impossible to get on the market...although there is probably more out there. Pabstite is hard to ID without the aid of the UV light as it glows bright blue under short wave. Once located in the matrix with UV, the crystals can be distinguished. In this specimen they are white to colorless and platy to maybe 1-3mm. The quarry is nonexistent I believe.

There are several colorless crystal grains in matrix. The largest at the arrow is 1.5mm, which is large for the species. The rest are smaller. All the grains are identifiable with UV since the fluoresce a bright blue. It is the tin analogue of Benitoite and very rare.

Pabstite is a rare barium-tin silicate and found at only four localities worldwide. The Kalkar quarry is the type locality. It is hard to identify the colorless crystals in matrix without the aid of shortwave UV. This is one of the richest specimen I've seen with grains to around 2mm.

Intensley fluorescent (SW) blue Pabstite grains. Pabstite is very difficult to identify without the aid of a fluorescent light.

Usually the only way to see Pabstite is by SW UV shown here. In normal lighting is non-descript but glassy. On this specimen it closely associated with white Tremolite. The fluorescent grains here on 1 to 5mm. This locality is no longer collectable as it is now buried and developed.
