Not sure what else to call it. I was half asleep the other night and the brain refused to shut down and was stuck in cabochon mode. I was thinking of using a low height bezel for setting a tall cab and came up with a ledge of sorts around the cab so the bezel could be rolled over the ledge to hold the stone, but the dome was substantially taller. Clear as mud? Grooved cabs were the inspiration with the bottom half of the groove as the "ledge" and the upper part of the cab above the groove cut away and polished. Anyone ever experimented with such a bastardized cabochon? It sure would add an extra flair to high end cabs, but would look like crap if not exceedingly well done!

Sounds really interesting. I've never thought of something like that. Guess now you'll have to do it and share a picture or two.

I agree with Tela - cut some and post images. I'm afraid I don't quite grasp the concept from words alone.
It doesn't take much bezel to hold a stone securely if there's a slight angle to the girdle. I've cut and set a lot of high-dome cabs with bezels only 2 to 3 mm. high. The bezels are stiff and need to be hammer-set but they look great. I guess I don't really understand why a special girdle is necessary, but maybe I'm stuck in that "clear as mud" puddle.

Are you thinking like giving the stone a muffin top? (sorry for the visual).

I set quite a high malachite cab using a relatively low bezel with the effect that the belly (to continue the muffin-top analogy) weight pulled the pendant forwards. I had thoughts along similar lines where with a grooved cab, the stem of a _|_ (viewed in cross-section) could be fitted in the groove, with both ends _ and _ (left and right, respectively .... haha!) running up and down the cab. TBH tho' it would be recommended more highly to get the cab in proportion rather than having to deal with the consequences.

Anyone ever experimented with such a bastardized cabochon? It sure would add an extra flair to high end cabs, but would look like crap if not exceedingly well done! I did something similar once when I was making a red tiger eye Scarab. I made a lip and then carved the cab that became the body of the scarab, while the lip was the surface that the grooves were cut into to depict the legs of the scarab. I tried to do a bigger higher red tiger eye Scarab after the first one, but the chatoyancy of the extra high dome cab was so brilliant once it was cut, that I couldn't bring myself to carve it into a scarab, but I had already built the lip and cab part so I was going to keep the lip and bezel the silver over the lip (like you are considering), unfortunately the stone fell and chipped the lip so I ended up grinding the lip away and just glorifying in the gorgeous chatoyancy of the high dome red tiger eye cab. i really recommend exaggerated high dome cabs for tiger eyes and other chatoyancy type stones.

radio , I have done some of the high dome cabs with shoulder's, it depends on the material. I have done some petrified wood and chrysocolla that way. Want the high dome effect, but needed a way to hold it a setting.

The two potential problems I see are; polishing the ledge, ledge to dome connection, an; the ledge will be a weak point. Not everyone has my heavy hands (thank goodness) but I would afraid I would break the ledge if I was setting with a conventional bezel.

Could all of you who have done something similar please post pictures? I think I understand radio process, but not the others. I want to try them all. Thanks

I had gotten sidetracked and completely forgotten about this thread! It still fascinates me, but the busy season is upon us in Branson, so it will have to be put off until winter and hope I remember to experiment with it then.
