Millerite, Calcite
Estabrook Park (Berthlet; North Milwaukee; Cementville; Lincoln Park; Capitol Drive; Washington Street Bridge; Humbolt Street Bridge), Milwaukee, Milwaukee Co., Wisconsin, USA
Miniature, 4.4 x 3.1 x 2.0 cm
This specimen features a geode vug with colorless, lustrous, calcite crystals, to 1.0 cm across, hosting two diverging sprays of lustrous, brassy, millerite, to 3.5 cm in length. An aesthetic and impressive millerite, to be sure! These came out in the 1960s from a small locality in the middle of a city park, and it is not possible to collect there any more. Specimens of this quality are very SCARCE. Actually, I am told it really was sort of a night-time thing in the past, too... 4.4 x 3.1 x 2 cm
