- Eleura Mine, Booroondarra, Cobar, Robinson Co., New South Wales, Australia
An artistic and aesthetic silver specimen from the Elura Mine of Australia. This tapered, doubly terminated grouping of spinel-twinned silver crystals a looks like a spine, and the curved form gives it elegance. These came out in the early 1990s, with very few since. A very fine representation of classic silver crystals!
