Basket setting for oval stones

I am looking for the mathematical equation to make a double basket setting for an oval stone. Thank you in advance

The way I learned to do this is not a mathematical process. You shape a ring that fits just under the girdle, then make another that fits just inside the first.

Sorry, there is not an actual equation because the end result is what looks good to your eye. But here are two videos that might help: How to Make a 4 Claw collet - YouTube and How to Make an Oval 4 Claw Split Bezel Collet - YouTube
