I would suspect this is going to be pretty costly. unless you can have one made in S/S. Any of the gold ones are going to be pretty expensive, as it looks pretty massive and a fair amount of gold will be used in each ring. I know that people have been clamoring for a price, not sure he has gotten to the point of pricing it. First off, I'm sure that the price point is going to be pretty high, can't afford to stock these, because of the different sizes. These are not rings that look like you can have them resized should it not fit, would need to go up or down with a completely different ring.
As I said before, I'm not a ring person, so absolutely no interest in this project except to say it is very nice work, and a lot of persistence o n the OP's part, plus a pile of money!!
