MV14AI9: Ba-rich Microcline (variety hyalophane)

This is a floater group of Hyalophane crystals from Busovaca—practically the only locality for fine specimens of this Feldspar-group species. The lustrous, translucent crystals are very obviously repeating double Baveno-Manebach twins.

ME26AF3: Ba-rich Microcline (variety hyalophane)

Floater group of crystals from the classic locality of Busovača, practically the only one for good quality specimens of this mineral. Crystals have very obvious double Baveno-Manebach twins, and they are colorless, transparent-translucent and very bright.
Zagradski Potok Mine, Zagradski Creek, Busovača, Central Bosnia, Federation of Bosnia and Herzegovina Bosnia-Herzegovina (1989-1990)
Specimen size: 5 × 3.7 × 2.7 cm = 1.97” × 1.46” × 1.06”

Main crystal size: 2.6 × 2.3 cm = 1.02” × 0.91”

TC2140MTP: Ba-rich Microcline (variety hyalophane)

Floater group of sharp crystals of hyalophane (barium-rich variety of Microcline), which form multiple twins, with a predominance of Manebach's law. Colorless, transparent and very lustrous.
Zagradski Potok Mine, Zagradski Creek, Busovača, Central Bosnia, Federation of Bosnia and Herzegovina Bosnia-Herzegovina
Specimen size: 4.5 × 3.9 × 2 cm = 1.77” × 1.54” × 0.79”

TH12H7: Ba-rich Microcline (variety hyalophane)

Group of very well-defined and bright crystals. They have a high degree of transparency and on both sides, more clearly at the left, the Baveno twin, typical of alkaline Feldspars, is present.

Specimen size: 2.8 × 2.2 × 2.9 cm cm = 1.10” × 0.87” × 1.14”

TB46G0: Ba-rich Microcline (variety hyalophane) on Quartz (variety smoky)

A group of prismatic crystals, with very good luster and definition of forms. It is attached to a matrix of Quartz, something that we had never seen before.

MT37AL9: Ba-rich Microcline (variety hyalophane) with Rutile inclusions

Floater polycrystalline growth of twinned crystals of Microcline (barium-rich variety hyalophane), from the classic Busovaca deposit, practically the only locality that has provided good collector specimens of this variety. The crystals are of good size, with very distinct double Baveno-Manebach twinning, translucent, lustrous, with abundant Rutile inclusions, which is unusual in this type of specimen.
