  • $ 12500

Ball of light brown strontianite with calcite. This is an exceptionally nice specimen of strontium/carbonate from mining circa 1980 which would put the specimen in the area of the North Bishop Tract which Allied and Inverness mined in the 1970s through 1980. Note curved terminations on strontianite as classic morphology. Choice miniature. Betty Kalaskie Collection #54. Ms. Kalaskie acquired for $5. in 1981 from Palmer's Trading Post in Cave-in-Rock (obviously a good time to buy).
