For those of you who want to make a custom platinum diamond engagement ring yourself, there’s actually a way using wax to mold your custom designs.
This certainly ain’t for the faint-hearted but for those of you who have the right tools, you might be able to get a custom design just in time for your anniversary or proposal.
This instructable shows you how his ring was created using the lost wax casting system.
To begin with I cut a section of jewellers wax, ( a special wax that has great properties for cutting, sawing and carving) into the basic ring shape. I created a hole the same size required for the finished ring.
