It really depends on what I find. Most wedding bands are just scrap gold. I have put rings on consignment at jewelry stores, I have sold some on E-Bay. Most lucrative is finding a private buyer by far. HOWEVER when you find rings worth into the thousands, it is hard to find someone with that much cash.
The trouble with jewelry store consignment is you really do not know what they sell it for. I don't trust people and I know that is my problem. About 5 years back I sold a store a half karat flawless diamond for a grand.
I sold this 14K Artcarved one on E-bay and got a good price for it.
This is the ring I got 2500.00 for. The main diamond is 1.1 karat and perfect.
If I think it has more than scrap value I will keep it and let people know I have it. I don't have to sell my gold right now so I am just hoarding what I find till the price goes back up.
I will NEVER go to a cash for gold shop. You want to be taken go there or a pawn shop.
