- 3.7 × 3.5 × 2.5 cm – Miniature specimen (fits into a 5 cm cube)
Sphalerite is simple zinc sulfide. Bragg & Bragg (1913) first solved the crystal structure of sphalerite; the structure type is taught in undergraduate mineralogy courses. Glocker (1847) named sphalerite using Greek root sphaleros for treacherous, since the mineral yields no lead on smelting.
This is a large twinned crystal of sphalerite, approximately 75% complete. There is a contact face on its backside. Quite a good example for a single crystal collection; more complete and larger than most. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. A Gene Tribbey label and collection card accompany the specimen.
