Agate after Shell from Dakhla area, Western Sahara, Morocco [db_pics/pics/J146a.jpg] Agate after Shell from Dakhla area, Western Sahara, Morocco [db_pics/pics/J146b.jpg] Agate after Shell from Dakhla area, Western Sahara, Morocco [db_pics/pics/J146c.jpg]

Fossil shell that has been replaced by translucent golden agate. These are found on the surface, having weathered out of the surrounding rock formations. There are about 40 different species found at this deposit. Although they could have weathered out of different formations, they are all believed to be Eocene in age. Most are broken pieces and weathered and perfectly preserved examples such as this are uncommon, probably less than 5 percent of what is found. Fine quality large specimen.

Cuprite crystals to 1.3cm on an uncommonly wide, flat Chrysocolla covered matrix. These came out years ago and are among my favorite Cuprite specimens as the Chrysocolla really sets off the Cuprite crystals. Crystals are undamaged with many more crystals present that are completely covered by the Chrysocolla. Areas of fibrous Malachite crystals enhance the look. Undamaged.


C677 - Cuprite on Chrysocolla $ 500
Mashamba West Mine, Katanga, Congo
small cabinet - 8 x 6.5 x 4 cm

Cuprite crystals to 1.9cm on a flat Chrysocolla covered matrix. These came out years ago and are among my favorite Cuprite specimens as the Chrysocolla really sets off the Cuprite crystals. Main crystal is sharp with just slight edge chipping in one area. There are also many more crystals present (can be seen along edges) that are completely covered by the Chrysocolla and could be exposed. Areas of fibrous Malachite crystals enhance the look.

Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683a.jpg] Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683b.jpg] Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683c.jpg] Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683d.jpg]

Thaumasite is a rare mineral in the Ettringite group, the best were found at the N'Chwanning. This is a rare matrix specimen - you used to be able to find small single crystals but now even those are hard to find. Matrix specimens were always uncommon, and I have only ever had one before, a similar piece to this one that I paid a similar price to Katherine Woest about 15 years ago. Crystals are a transparent yellow and reach 5mm in diameter. White tufts of Xonotlite are dispersed between the Thaumasite crystals.

Matrix covered by Andradite crystals in turn coated by numerous well formed Hausmanite crystals. Clean and undamaged. Comes with a Wendel Minerals label that indicates it was formerly part of the Mayer collection.
