Anne and I have been mining these beautiful quartz crystals since 1994. Our first introduction to Herkimer Diamonds was at the Bancroft Ontario, Gem & Mineral show. About a month later, while browsing the showroom of the Dwyer Mine in Wilberforce, Ontario we located an old Lapidary Journal featuring Herkimer Diamonds. This led us to the Ace of Diamonds mine where the hunt for Herkimers was on. The rest, as they say, is history.

We mine from the 1st of April until the 31st of October. Our mining experiences have introduced us to a wide variety of interesting people (some have become good friends), fellow rock hounds, miners, collectors and people from the meta-physical world.

We have collected an amazing assortment of crystals and also have faceted jewelry available for purchase.

Anne and I look forward to hearing from you and sharing our enthusiasm for Herkimer Crystal.
