3.0 x 0.7 x 0.5 cm (Largest). An excellent 3-piece set of artistic and aesthetic silver specimens from the Elura Mine of Australia. These tapered, doubly terminated groupings of spinel-twinned silver crystals look like quills, feathers or swords. Both of the larger, sword-like crystals are slightly folded, giving the appearance of hollows or grooves. These came out in the late 1980s, with very few since. A very fine representation of classic silver crystals.
