I have a beautiful brooch / pendant.

I would be happy to answer any questions you have.

I sell it using bitify because they have escrow service.

Natural shell cameo depicting a young lady in profile, for wear as a brooch or pendant. Finely hand carved and set in a solid 18 carat gold mount. All original and in very good conditions.

DIMENSIONS: approx 2,8 x 3,5 cm - 1,1 x 1,4 in
WEIGHT: approx 7,6 g

Questions for OP:

How did you come to a price of $490? Do you have additional pictures of the hallmarks showing the gold purity being 18ct?

I do not see this being worth $500, or close to it. The amount of gold in this is insignificant. You might have more luck selling this on eBay, and not a Bitcoin Forum - these are somewhat popular on eBay, and you may get a couple hundred dollars for it. Good luck with your sale.
