"The Lost Wax Process"
I'll simplify this- mainly because I'm not an expert, but I have a good working understanding.
The lost wax process is one of the main methods used in jewelry manufacture.
The first step involves creating a wax model of the piece. More on how that is done below.
We take the wax model and pour plaster around it.
Then you let the plaster harden.
Then you bake the plaster- melting the wax, and leaving a perfect "impression" of the wax model.
Then molten metal- platinum or gold- is poured into - or injected into- the plaster impression.
After the gold or platinum hardens, the plaster is broken away, and you have your part.
Many of the rings we manufacture have quite a few parts. Unless we craft the part in platinum or gold, by hand, each of them must be created in this manner.
It's far easier to work in wax, which is why most parts are made using the lost wax process.
So- back to creating the wax model.
One method involves using a computer. CAD- Computer Aided Design.
The computer inputs the precise measurements of the diamond, and the ring is designed around it.
There's a lot of rings which are perfectly suited to this type of design. Like anything else, there's people that are far better than others- so quality varies.
Here's a design idea someone sent us. and the wax model we made- after repeated attempts.
It was not an easy one.
This is what we worked off of:
Here's the wax
The second method of working with wax is when it's carved by hand.
There's advantages to both methods.
Hand carving can result in a piece that looks ...handmade.
Some people prefer that look.
