Gold Bearing Quartz is one of the world's rarest forms of natural gold. It is found underground by hard rock miners in only a few locations in the world. Most of the World's production comes from a handful of mines in Northern California.Details
Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.Details
Gold in quartz is one of the most collectable forms of natural gold. Unlike gold dust and nuggets, gold bearing quartz is still encased in the quartz rock, creating a natural high contrast display of beautiful gold with white quartz. Mineral collectors will gladly pay many times the gold value for certain specimens.Details

Hampshire’s gold bearing bedrock broke the rock apart naturally. However, gold does not weather, and this allowed the more resistant gold pieces to be washed away by running water. Gold is approximately 19 times heavier than the same volume of water and gets left on the stream bottom with other heavy rock and mineral pieces.Details
