![Prehnite from Merelani Hills, Arusha, Tanzania [db_pics/pics/K464c.jpg]](db_pics/pics/m/K464c.jpg)
Rosette shaped groups of translucent yellow Prehnite crystals. Great color and large crystals, this is one of the finest specimens from a large lot of recently mined and purchased Prehnite specimens from the Merelani Tanzanite mines. The back smooth and flat where it grew against Graphite. It's pristine except for light chipping along the top edge and a partial Tanzanite crystal intergrown in the lower right side.

Rosette shaped group of translucent yellow Prehnite crystals. Great color and large crystals, this is one of the finest specimens from a large lot of recently mined and purchased Prehnite specimens from the Merelani Tanzanite mines. The main rosette is 4cm tall and sits nearly vertically for display. The larger crystals appear to have grown from a central sphere of Prehnite. The bottom is somewhat flat where it grew against Graphite. It's pristine except for light chipping on some crystals and a contacted backside.

![Silver in Calcite from Cobalt, Ontario, Canada [db_pics/pics/K400c.jpg]](db_pics/pics/m/K400c.jpg)
Thick, heavy vein section of Silver in Calcite, a 2.3cm thick slab sawcut on both sides. There is a layer of solid Silver along the more straight edge, with the rest of the specimen filled with more dendritic Silver. Visually, it appears to be 40-50% Silver, and by weight, a much larger percentage. The specimen weighs ounces and was the best slab (richest, largest, thickest) out a large lot of Cobalt Silver I purchased from a Canadian miner over 20 years ago.

![Garnet, Dravite in Graphite from Red Embers Mine, Erving, Massachusetts, USA [db_pics/pics/K510d.jpg]](db_pics/pics/m/K510d.jpg)
3 red Garnet crystals in a matrix of grey Graphite. Small dark crystals of Dravite are also embedded in the Graphite. The Garnets reach 12mm in diameter and have been analyzed as mostly Almandine with a touch of Pyrope in the outer layers. These make stunning specimens due to the fact that the Graphite has been removed from around the backs of the Garnets allowing light to pass through the crystals, creating glowing 'red embers'.

![Brucite from Killa Saifullah, Balochistan, Pakistan [db_pics/pics/K362c.jpg]](db_pics/pics/m/K362c.jpg)
Bright lemon yellow Brucite crystals from the original finds of a couple years ago. I looked through hundreds of specimens to find the brightest, most deeply saturated yellow specimens such as this. This specimen is solid Brucite and is well crystallized on both sides. The bright yellow Brucite formed as a second generation over a thin piece of white Brucite. These new specimens from Pakistan are world's best for the species.

![Tourmaline on Quartz from Pederniera Mine, São José da Safira, Minas Gerais, Brazil [db_pics/pics/K511h.jpg]](db_pics/pics/m/K511h.jpg)
Large, floater specimen of multi-colored Tourmaline crystals on a large Quartz crystal. This is an old specimen dating back to the early days of the mine (I am told the 1980s). Even though they are all from the same pocket, the Tourmalines show a variety of colors and form - some with dark terminations, others with yellowish terminations, and some with pink cores. The best is a 4cm well terminated crystal of transparent green with a yellow termination. The Quartz crystal is rehealed on the bottom. This is a great (and inexpensive) specimen for a collector who wants to put together a Pederniera collection reflecting the various pockets and styles found at the mine.

Intergrown rosettes of translucent green/yellow Prehnite crystals. Great color with large distinct crystals. Well crystallized all around and nearly a floater with just a small area contacted against Graphite. Slight chipping is present but overall in great condition and a very good one for Merelani Prehnite.
