I have seen the adjustable shanks in Rio and Stuller and have even
written to one…perhaps Finger fit, with no reply, even though
their website states they do custom jobs…mmmmmmmmmm.
The adjustable shank I saw opened and was smooth on the botton of
the ring…no buckle bulging out. The simple mechanism was inside
the shank and it opened when the customer pulled up on her solitaire
diamond. It reminded me of the kind of closure one would see on a
hollow bangle bracelet, except that it didn’t open all the
way…just enough to enlarge the size to get on and off. This one
was no lightweight either and it was a tight fit and worked great.
Her ring was yellow gold and the device, when opened, was white gold
Anyone ever see such a device?
Thanks to everyone who replied about the ring shanks thus far.
