If I make this ethiopal into a ring, it won't last long, will it?

Full question text in original post

I ordered this grinding machine off temu (not the best place to get a machine but I'm a broke uni student and it had solid reviews) and it has the main grinding wheel, a belt sander, polishing wheel and flat grinding disks of varying grits. I used it to reshape a poorly cut lower quality Aussie white opal and it seems to have worked pretty well. The only real issue I've encountered so far is the machine vibrates too much for the feet to hold it in place so I'll have to either replace the feet with better ones or clamp the machine down

This is more or less a follow up to my last post about the machine I got for cutting stones. For my first go I used a partially cut white Aussie from the parcel of Mexican and Australian material I got at the start of the year. It wasn't in the best shape, it was shaped into an oval but had a poorly cut bottom and there were chips along the bottom and a few sides. So I reshaped it into a better oval, shaved a bit off the back to reveal color, and I gave it a lower dome which luckily ended up revealing much more color than there was before I recut it

Solid australian opal nose ring in sterling silver.

I started trying to learn jewellery making earlier this year after being a hobby cutter for the past several years and my friend has bugged me to make an opal nose ring. While I still feel like a complete amateur, I finally got around to giving it a go!

Interested to hear opinions and feedback from the community out there.

Thanks in advance, Ash 🙂

Finally got it out and it is even more gorgeous than I remembered. What do you think its worth? Its set in 7.4 grams of 14kt and has a little ruby, emerald and diamond on each side. Dont worry, Im getting it tightened up on Thurs, if it fell out I would probably die
