He did a great job with the diamonds in the band. They taper down in size beautifully. I also cracked up that you used aluminum foil to do a mockup. That's brilliant!
This ring is such an awesome PS success story!! Finding the stone on eBay - knowing what to look for and what to guess at, taking a chance on a promising CS resource, choosing the right vendor to craft the setting and shipping the stone around the world to make that happen, buying preloved sidestones and matching others...
And oh my goodness did it end well!!! Your ring is beautiful I love everything about it!! That glorious center, the E/W orientation... And the subtle, concave sidestone taper is absolutely perfect... Love it paired with your matching bracelets, too!
I saw the CADs and I knew it'd be a lovely piece, but seeing it complete I have to say I'm completely blown away - I can't wait for your next project!!!
