Stunningly attractive specimen of transparent Quartz with bright, brassy Chalcopyrite crystals. These are fairly common minerals, but in a combination and form to produce this beauty. Both minerals are evenly distributed and in good condition with just a few missing Quartz crystals. The Quartz are uniform in size and transparent. An overall very bright and showy specimen.

Individual spheres of yellow Prehnite grown in and around flat crystals of white Calcite. This is one of the most beautiful Merelani Prehnites I've ever seen. A fibrous blue Tanzanite and small white crystals (Laumontite?) are attached to the backside. A floater with no points of attachment and little to no damage.

![Prehnite from Merelani Hills, Arusha, Tanzania [db_pics/pics/K233c.jpg]](db_pics/pics/m/K233c.jpg)
This is a very interesting Prehnite composed of an almost perfect sphere of solid Prehnite, like a translucent gumdrop, with larger crystals growing out of the sphere in various directions.

Spherical, mound-shaped Prehnite with large, chunky crystals. This is a very good one in terms of form, size, color, and quality. Nearly pristine with just a couple minor nicked crystal tips.

Solid, translucent yellow Prehnite with large, chunky crystals. This is a very good one with a little contacting on the left edge and a partial Tanzanite attached near the base, but the entire front display face is perfect undamaged large crystals. This grew against the flat surface of a large Calcite crystal and the backside is flat and smooth.

Translucent blue/green Prehnite crystals with both a color and form new with these late 2018 finds of Prehnite from Merelani. These recent Prehnite have rounded orb formations that morph out into flat bladed crystals. The color, a blue/green/yellow is also a little different than I've seen before in Merelani Prehnites. Undamaged.

Large, gemmy Tsavorite crystals on a matrix of solid Graphite. The Tsavorite have good color and transparency and reach 1cm in size. There is a bit of chipping which keeps the price much lower than it would otherwise be. Regardless, it displays well with good color and crystal size.

Bright citrus orange Spessartine crystal, complete all around. Equant form with gem zones. There is one minor edge chip and some natural small surface pits, but no significant damage. This is a good one, with minimal black inclusions that negatively affect most of these. The intensity of color and gem zones are even more apparent with backlighting. These are no longer being found. Weighs 26.8 grams.
