Glassy, colorless, lightly frosted calcite scalenohedrons showingly cover marble matrix on this exceptional California specimen from the John Sinkankas Collection. The dogteeth calcite crystals reach 2.5 cm and this fine piece is essentially pristine. I obtained this from John in 1998 or so and kept it in my calcite collection since, never having seen another example from here to compare it to. The specimen was collected by his son in 1972 from the Kaiser Steel Mine, Eagle Mountain in Riverside County. This is an UNCOMMON California locality.
