If you have seen this style of jewelry called "Electroformed Jewelry", and have been interested in how it is produced then this book is for you. This book walks you through two different builds in case you want to try out the hobby before committing to the cost. The technique can be used in many hobbies not just jewelry, coating 3D printed objects, preserving organics and glass-work just to name a few. This hobby is very fun and slightly addicting so be careful once you start you will be picking up small things, electroforming it just to prove to yourself that it can be done. Then make a necklace out of it.
