From: Ace of Diamonds Mine, New York, USASize: 5.0 x 7.7 x 3.5cmWeight: 102g This is a very attractive, lustrous and clear Herkimer "diamond" quartz cluster with 10 quartz crystals. The black specs are bitumen which is a petroleum inclusion. The condition is excellent with no damage. Like almost all Herkimer clusters this one has been restored. Typically when these large clusters are found the individual crystals can become detached and are put back together, but all of the parts are legitimate and correct.The mineral specimen comes with a labeled acrylic display base.
