- Tincalconite, Hanksite
- Small Cabinet, 8.0 x 6.0 x 5.5 cm
- Searles Lake, San Bernardino Co., California, USA
A superb combination specimen of rare species from Searles Lake, California and the Jim Minette Collection. A pristine, doubly terminated, sharply hexagonal, translucent hanksite crystal is aesthetically capped by snow-white tincalconite pseudomorphing a very blocky borax crystal. Hanksite is a rare sulfate and tincalconite is a rare borate. Searles Lake is the Type Locality for both species.
