Electroforming or electroplating is a intricate process where copper is strategically built up over time onto a conductive surface through electricity. Each piece takes a minimum of 24 hours just for the plating process alone. A very creative way to make the metal look like it is melting around whatever it is that you are encompassing. Copper is also an amazing energy conductor so whatever vibe the crystal is giving to you and the universe it will be magnified!
Simply put, science is magic and thats how it happens people.
