Re-facet Rubies and Sapphires to fit ring.
A local jeweler/designer had a customer who wanted a very special ring made. The design would be a star patter which had a special meaning for them.
They wanted the star pattern to be composed of special shapes of stones. These shapes are not available in that pre-cut shape. They would need to be special cut.
The jeweler provided me with the measurement specs from his CAD program which gave us the lenght, width, and angles which I needed for the shape of the stones to fit the ring. I then calculated the sizes of stones I would need to re-cut into the sizes they needed. Then the jewelers contacts their sources.
Below, you will see photos and description of the cutting process.
Stones I began with
At the left you can see the marquise Rubies and Sapphires which the jeweler acquired from a gem dealer.
The are nice, clean, high quality stones. I have already dopped one of them to start working on it.
By working on stones which are calculated to be just large enough to cut the final size we need, the jeweler saves money by not purchasing gems which are larger than are needed.
After re-cutting
Now you see one of each of the finished stones. The shape of the Sapphires is different from that of the Rubies.
I decided to use a cissors type cut on both the crown and the pavilion. That gives the stones more brilliance that the stones would have if they were simple step cuts. It takes a bit more time to do the cissors cut but it is worth it in brilliance.
The jeweler asked me to take the sharpness off of the points so as to prevent chipping.
