Sharply formed, lustrous black tetrahedral crystals of Sphalerite, some with small Sphalerites growing fromt he sides of the alrger crystals. Fine quality crystals.

Dramatic cluster of angular Silver crystals, capped by a superb 1.2cm crystal. Tiny amounts of Copper are present on some of the crystal faces.  Nothing but good, large crystals. Fine!

Well crystallized, arborescent group of Copper crystals with a nice patina.

Solid mass of Acanthite and Polybasite crystals - there are hundreds of Polybasite crystals along with tiny cubes of Acanthite. This specimen came out of a collection that was built in the 1970s, so dates back at least to the 70s.

Showy specimen of Cuprian Adamite on Calcite with crystals to 1.3 cm long. Good sized crystals that present dramatically for display.

Large white rhombs that reach 1.5cm wide in a near floater cluster - just one small point of attachment in center of backside. Bright white on the front with reddish brown colored crystals on the backside - crystals on backside are just as lustrous on the front. No matrix, nothing but very high quality crystals and no damage, very good specimen.

Single Tanzanite crystal with a Pyrite crystal attached to one side of the crystal. Pyrite is not unusual from Merelani, but Tanzanite specimens with attached pyrite are uncommon, especially those with the pyrite perched so aesthetically on the Tanzanite. The Tanzanite is also a bi-color with a yellow termination over a blue body color. Unusual addition to a Merelani suite.

Water clear 2.8cm Quartz crystal attached to the front of a partial Tanzanite crystal. Some small, bright yellow Prehnite crystals add some color contrast to this unusual specimen. The left side of the Quartz crystal is coated by a druse of white Prehnite, and there are even some Graphite crystals attached.

Large, single Epidote crystal with impressive size and an unusual multiple termination that has a satiny sheen as light relects across its surface. This locality has produced great Epidote crystals over the years - they are not transparent but have great form and large size. This crystal was mined in 2011 and is the biggest of the 30 or so crystals found.
