EY48AK8: Malachite pseudomorphic after Azurite crystals, very sharp and aerial, with simple crystal forms with fibrous surfaces and satin sheen. Highlighted by small Copper crystals that accompany the Malachite - a rare association. An excellent American classic.
This specimen, from Doug Toland's collection, is accompanied by an old Roberts Minerals label that we will send to the buyer.

Specimen size: 10.7 × 5.2 × 5.5 cm = 4.2” × 2.0” × 2.2”

Main crystal size: 2 × 2 cm = 0.8” × 0.8”

MM6AK8: Specimen similar to those reported as a novelty from the 2019 Sainte Marie-aux-Mines show but exhibiting distinctive characteristics, apparently due to having been found at greater depth than the previous finds. Calcite crystals, one of them clearly dominant, have a sharp pseudohexagonal contour and are completely covered by a second generation of small scalenohedral crystals, together with Quartz, in small crystals, along with Epidote, much more individual and of higher quality. We analyzed this type of specimen due to its genetic complexity and we will send a copy of the analysis to the buyer.
