If it's a diamond, I'm sure. There is no diamond repurchase business, and other brands have not heard of it for the time being.

First of all, I suggest you call their store first and ask if there is any gold repurchase business. If yes, ask about the conditions and shops for repurchase. Not all stores can, and the same is true for trade-in. Then you can go to the store to deal with it. If you don't want to get a new one or use this brand, you can try to find a pawnshop and exchange some money.
If it's a diamond ring, I'm sure, but just in case, you might as well call and ask. . .
