Large Geode Slice Copper Electroformed Crystal Necklace

This handmade necklace features a stunning large geode slice with many intergrowths of smaller quartz crystals inside.

Electroforming is the process of depositing raw copper onto any object which has been made conductive of electricity. The object is placed in a chemical bath as a cathode (positive) with a copper wire as an anode (negative). Through the process of electrolysis, an electrical current is run through the copper wire, causing the copper ions to displace in the solution and “stick” to the object which has been immersed. This builds layers upon layers of copper plating until the metal reaches the desired thickness, so the plating process takes several hours.
