Dims: 6" x 4-1/2" x 3-1/2"
Wt: (over 5 lbs.)
Searles Lake, Trona, California, U.S.A.
This specimen has both the largest cluster and the largest crystal of Hanksite that I have yet seen. The cluster itself weighs in at about 5 lbs. The largest crystal likely takes up 1/3 of that weight-- its diameter measures approximately 4 inches and it rises over 2-1/2 inches out of the cluster! Being clustered, none of the crystals is complete with a double-termination. Only a few, however, have damage, and that damage is minimal. Their crystal faces and edges are rough but complete and all are a gray-green coloration and are translucent. They occur in the hexagonal prisms, each with the basal primary and beveled secondary terminations that are common for this mineral. On the underside of the specimen one can see thin, reddish blades of trona, a sodium carbonate mineral that occurs with Hanksite and other evaporite minerals. This specimen is quite BIG, and has been given the obligatory coating of oil to prevent dehydration.
