DT gemmy San Diego County Heliodor (ex. Robert Bartsch Coll.)

Yellow-green beryl from the obscure and extinct Mack Mine is RARE. Most of the very glassy, doubly terminated, yellow-green crystal is limpid gem. One termination is strikingly translucent, yellow-white. Complete all-around and nearly pristine. Part of the basal termination (no damage) and the back of the crystal are contacted (minimal damage, with only an upper broken edge). A VERY RARE gem beryl from this pegmatite, that is now on Indian casino land. 33.55 carats or over 6 grams mass. Self-collected by Robert Bartsch in the late 1950s to early 1970s. He was a noted California field collector and collector.
