Description |
The borate deposits of California have produced some really beautiful/unusual mineral specimens. Few are as unusual as Ulexite. This particular matrix specimen is features a radiating spray of discrete Ulexite needles, something you almost never see in the mineral. The needles have superb luster and a pearlescent, white to tan color. The Ulexite needles are in association with some tan, translucent calcite crystals in rounded masses. Ex. Jim Minette Collection. |
