- Calcite on Alstonite
- Large Cabinet, 23.5 x 21.7 x 7.5 cm
- Bethel Level, Minerva Mine #1, Hardin County, Illinois, USA
- Ex. Ross Lillie
A thick slab of micro-crystallized, sparkling, white alstonite is the matrix for five clusters of scalenohedral, lustrous and translucent, tan colored calcite, to 3.5 cm in length. Some damage to calcite tips is evident but this is tolerated due to the rarity and importance of the specimen as a whole for its rich and fine alstonite crystals that have such unusual luster to them. Mined in the 1940's to 1950's according to his label, and from the Ross Lillie collection. RCL#2173.
