This platinum band is set with french-cut jet or onyx,and has gorgeous engraving on the sides. It's a size 6.5, and probably not a good candidate for sizing. When I first got his band, a few stones were a little loose in the channel, but I took it to a jeweler this weekend and had it looked over and the channels tightened on the principal of "better safe than sorry," and now it's in wonderful shape.
There are a few surface abrasions on the stones under the loupe as would be expected for a piece this age featuring softer stones, but on the whole, I'd say it's in great vintage condition ... and though black and white was a perfect fit for the sleek, stark Art Deco aesthetic, not too many jet or onyx bands have survived. Rare!
You'll find pictures covering its circumference below, but it you would like shots from any additional angles, or if I can provide any additional information, please don't hesitate to get in touch!
