Even so....I’m especially intrigued by that tension mount.
That’s pretty neat.
Tension mounting is pretty risky for a 6.5 carat stone… we tested it extensively before we decided it would hold. Usually it’s not used for anything larger than a 1-2carat stone, but the triple prong approach was robust enough.
We tried a straight tension mount for my 16.5 carat stone, but it wouldn’t stay tight. We had to add the prongs to keep it in the mount. I was not pleased about my straight clean lines being broken up by the prongs, but I’d have had to go down to a stiffer gold content (say 10 karat) and even that would have been iffy. I did not want to risk losing the stone. Even so, the prongs need to be tightened every three months or so, if I wear it daily.
