- Aragonite var. Cobaltian
- Richelsdorf District, Hesse, Germany
- Small Cabinet, 7.5 x 4.7 x 0.8 cm
- Ex. Kay Robertson
Very fine, thin plate of Aragonite (often referred to as 'Cobaltian' Aragonite for the color) from the Richelsdorf District in Germany. Of the pieces of Aragonite I have seen from there, this is one of the most substantial and uniformly colored plates. The undulating surface teeters on the edge of being botryoidal, and certainly it has fine aesthetics for what it is. An unusual rarity!
