Took in this ring for repair yesterday and recalled a thread not long ago about setting stones with glue. This is the perfect example of why it shouldn't be done in a quality piece. 18 Karat gold ring with a good size diamond, but who ever did the piece took some shortcuts in setting the Onyx. This ring is about 8 years old and the glue has already deteriorated badly allowing the thin Onyx stone to crack and pieces of it fall out. I will use a diamond burr to deepen the recess a bit and level the base before cutting and setting a new stone. I will also drill 4 tiny holes through the gold so the liquid steel I use will form pillars and not allow the stone to shift and crack like it did before

Most definitely not a two part epoxy. Yes, it is a big repair job and was priced accordingly Gonna be a real bear to cut and fit new Onyx, especially that thin. I most likely will leave the stone a bit thicker than needed, set it with liquid steel, allow it to cure then very carefully work the stone level with the gold

Maybe, he should leave his ring at home. Would be cheaper.

Wickipedia description>>> en.wikipedia.org/wiki/OnyxI stipulate onyx is black agate. Where does black onyx come from? I know a hard rock place to get some, but not commercial qty...

True Onyx is striped agate, most black onyx is dyed. Sardonyx is red striped instead of black. Some refer to Travertine as onyx, but it is not. en.wikipedia.org/wiki/Onyx

Have you thought about replacing it with black jade? Way less chance of it breaking or chipping. Jim

Jim I thought of a few different alternatives, but never thought of Jade. any suggestions where to pick up just a small slab, or even a cab I can re work? I have some killer Psilomelane, but the patterns in it are quite pronounced, so I ruled it out

(note that when this jade gets cut thin enough - say 1 mm thick, it turns green. But I am sure you will be thicker than that so it will look black.

Here is some onyx. Nowadays it is called onyx and that's fine with me as long as I understand it is limestone onyx (travertine) as opposed to striped agate.

I pick up black onyx, naturally occuring, at the coast on the Cote d'Argent, near Bordeaux, France; generally only small tho.

(note that when this jade gets cut thin enough - say 1 mm thick, it turns green. But I am sure you will be thicker than that so it will look black. Thanks! I have not measured for the stone yet, but likely about 15mm at the long point and perhaps 12mm wide. The recess it was set in is currently very shallow, but I plant to use a burr and deepen it slightly. I'm guessing it will be 2 mm thick or perhaps a shade over that. This is likely not the last piece I will take in to repair, so would gladly buy a slab from you as long as it is dark enough to be suitable for a Black Onyx replacement message me with details thanks
