Dolomite- cast with two generations
stock #16.1-305
Tsumeb
Otjikoto Region, Namibia
6.5 x 3.8 x 2.8 CM (cabinet)
price: $190
Dec 2018

A delicate and fine Dolomite cast having two separate generations. The large scalenohedral shapes are hollow having just a thin skin of Dolomite that had covered what were likely Calcites, now long gone. The matrix is an earlier generation itself just a thin skin of tiny sparkling crystals. The Dolomite casts from Tsumeb were found in many exotic forms are are very collectable. This one is in perfect condition, esthetic and looks fine from all sides.
Dolomite- Penetration twins, gemmy crystals
stock #18- AX-19-153
Cantera Nueva, Eugui
Navarra, Spain
7.1 x 6.3 x 3 CM (cabinet)
price: $420
Worldwide mix summer

A fine transparent cluster of Dolomite crystals from the classic Spanish locality of Eugui, Navarre. An uncommon matrix piece, the crystals are up to 4 CM in diameter and very sharp, undamaged. Dolomite is a very common mineral and crystals are not rare at all, but sharp, gem clear Rhombs like this are really only found at this one locality and they are very rare in such quality. Some minor dark zoning is seen but overall these are white to colorless and mostly transparent. The penetration twinning is textbook sharp and clear, an excellent piece found in 1998.
Dolomite on Quartz
stock #14.1-334
Williamsville Quarry, Poplar Bluffs
Missouri, United States
6 x 4 x 3.2 CM (cabinet)
price: $110
Spring 2017

A very colorful Dolomite, bright yellow to Orange bladed crystals contrast well with a dark druzy quartz matrix. I have not seen another specimen like this piece from this locale, better known for Calcites. Super showy and in fine condition.
