An extremely elongated Tsavorite crystal with attached Pyrite crystals. Fully crystallized all around and undamaged, even the bottom end has some crystal faces present. This is the longest elongated Tsavorite I have yet seen from recent production.

Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656a.jpg] Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656b.jpg] Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656c.jpg] Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656d.jpg]

Rare large cluster of Rosasite after Malachite after Azurite crystals, the largest cluster I can recall ever seeing. Note that this has been repaired in a number of places. This came out of an old collection and the repairs have not been done to modern standards, so it could be greatly improved. There are five large crystals that comprise the group. Just a rare and spectacular piece.


T657 - Malachite on Chrysocolla after Malachite $ 1200
Katanga, Congo
cabinet - 10 x 8.5 x 4 cm

Malachite on Chrysocolla after Malachite from Katanga, Congo [db_pics/pics/t657a.jpg] Malachite on Chrysocolla after Malachite from Katanga, Congo [db_pics/pics/t657b.jpg] Malachite on Chrysocolla after Malachite from Katanga, Congo [db_pics/pics/t657c.jpg]

The Katanga region of the Democratic Republic of Congo is the Malachite capital of the world, yet most of the Malachite is lapidary grade with only a small percentage (usually fibrous or stalactitc specimens) being of any interest to mineral collectors. With specimens like this, Katanga can also claim to be one of the best localities for perfectly crystallized Malachite too. This specimen features perfectly formed individual crystals to 1.3 cm on a colorful and contrasting matrix of sky blue Chrysocolla. Just fabulously sharp single crystals.The Chrysocolla has partially pseudomorphed an earlier generation of Malachite crystals.

Fine quality Vanadinite specimen loaded with red crystals to 2cm over a thin matrix, essentially nothing but crystals. Undamaged, which is difficult to find in a Vanadinite specimen of this size with so many crystals.  A real beauty, the pics say it all.

Large open vug lined with Quartz over Chrysocolla with isolated clusters of dark green Clinoatacamite. At the lower right is a single 4cm Selenite crystal grown over a Clinoatacamite cluster. Uncommon for both overall size and the great isolation of the crystal clusters. These are regarded as the world's best Clinoatacamite specimens.

Fine quality elongated Tsavorite crystal from recent production (2017) that has been producing these stange, elongated crystals. Many of the new crystals, like this one, exhibit a faden line running up the C-axis. This is an undamaged floater cluster of a few interconnected crystals.

Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717a.jpg] Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717b.jpg] Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717c.jpg] Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717d.jpg]

Large, exceptional Copper 'Skull', a cast of Copper formed when Copper coats a rounded nodule in a conglomerate with the nodule later eroding away leaving the "skull'. This one is both good sized and exceptionally well formed (complete) and preserved. Many get smashed or dented or are only partial hemispheres. I'd say this one has about 80% coverage of what was the former nodule.
