Datolite

Drexel Mine, Keweenaw County, Michigan. Good size pair with unique color. Kind of a yellow undertone with a mauve color overlaying it, set off by the 2 different colors of veining. 6.2 x 5.5 x 3.2cm SOLD TM21-1189

Silver Crystals

Copper Falls Area, Keweenaw County, Michigan. This miniature is from a new find made in 2019 by a local collector who unfortunately passed away last year, but had a friend sell these silvers to help pay off medical bills. I obtained this from another dealer, and it is made up of small silvers running through a prehnite matrix. 5.3 x 2.3 x .7cm $135 TM45-233

Datolite

Nassau Mine, Ontonagon County, Michigan. Choice datolite from this small mine in Ontonagon county. Translucent tan with tiny flecks of pink, in perfect condition, front & back. 4.2 x 3.2 x 1.5cm $55 TM21-1190

Copper Crystals
