Hi and welcome! So sorry to hear about your broken ring... was it a cabochon set in a metal band, or was it a completely stone ring? Can it be repaired or reset? I love black jade. I know some people feel uncomfortable wearing banded or hinged bangles because a jade bangle is supposed to be "protective" and if broken, then it's done its job as a protector. However, I would have no qualms about wearing a bangle that is banded or hinged if it is grade A, pleasing to my eye, and a friendly price. haha
I'm not usually superstitious, but I did purchase a used bangle that kind of felt "angry" for the lack of a better word. It didn't change till I paired with another bangle that seemed to "clear" it . It was a very unusual feeling. Now, any new bangles go with me to the beach at least once to bath in the salt water which is supposed to be "cleasening", and that seems to settle everything to neutral.
Thanks Junkenpo. It's reassuring that there are people buying hinged pieces. Let me find out more details on the piece from the seller and will decide from there!

The ring is a complete stone ring with a gold plated butterfly on top. Ring was cracked and broken in half! Still keeping it in my jewellery box but it's beyond repair unless glueing it....! Sad...
