Choice, large doubly-terminated gem crystal of vivianite. The crystal is a vibrant, deep green and completely transparent. There is a small amount of the typical sandstone matrix attached. A superb example from this find. 7.0 x 2.6 x 2.6 cm.
Well-formed crystals of augelite to 2 cm on matrix with tiny needle quartz. Machacamarca was the first locality that produced well-formed augelite crystals! Nice specimen of this rare phosphate. 9.1 x 6.4 x 2.2 cm.
From the find in the late 1970's, this is an excellent small cabinet specimen of violet hydroxylherderite on a matrix of tan lepidolite. The doubly-terminated crystal on the left measures 1.9 cm and the large vertical crystal measures 1.0 cm. Both are undamaged. There are numerous smaller crystals scattered on the matrix. 7.0 x 5.3 x 2.1 cm.
From the type locality, this is a large specimen of translucent brazilianite crystals measuring to 6.4 cm. The crystal surfaces are somewhat rough, but the crystal form is good. Fluoresces a pale yellow under LW UV. 9.8 x 8.1 x 6.7 cm.
3.3 x 1.9 cm crystal of hydroxylherderite on matrix with cleavelandite and lepidolite. There are numerous other smaller crystals present, as can be seen in the photos. Mined in 2004, this is the largest and finest specimen I have seen from this locality. Undamaged. 14.6 x 12.0 x 5.1 cm.
Wonderful small specimen of doubly-terminated rose quartz on feldspar with a dusting of eosphorite. The rose quartz crystals have good color and luster, and measure to over 2 cm. The eosphorite is on both sides of the specimen. 2.9 x 2.6 x 1.7 cm.
Beautiful topaz and quartz specimen. The 5.6 cm topaz has an interesting etched termination. The smoky quartz has been reattached to the topaz. 8.1 x 6.7 x 4.6 cm.
The color of the crystals is superb, reminding me of the finest from the Pulsifer Quarry in Maine. The main face features two doubly-terminated crystals to 1.3 cm along with a smaller, unterminated crystal. Both main crystals have a partial coating of massive quartz. The color is distinctly zoned and lighter towards one end. Minor bertrandite is also present. 2.6 x 2.6 x 2.1 cm.
A great miniature specimen of fluorapatite from Brazil. The color of the crystals is superb, reminding me of the finest from the Pulsifer Quarry in Maine. The main face features a doubly-terminated crystal measuring 1.3 cm along with several smaller, terminated crystals. Some light tan bertrandite is also present. 4.4 x 3.7 x 1.9 cm.
