Rabbit who are you to tell them they are over priced? You generally deal with fake silver items as you state here a lot. You have no idea what the OP has had to pay for their items or their overheads and then the profit margin so how can you judge the asking prices without all their info of costs involved? People will only get what they pay for and there is NO negs for the seller and no over priced comments so ALL the buyers are obviously more than happy to pay for quality items.

You may actually be surprised at how much I know about the wholesale jewellery business😄

And, I don't generally deal with fake silver items at all - you know NOTHING about my expertese.

What a seller has paid for an item has NOTHING to do with it's real value. I know sellers who pay hundreds for the same items I (or anyone in the know) can buy for $50.  A seller can put whatever asking price they want on their stuff, but, I do know wholesale jewellery and I do know that most shops put 400%-500% mark up on their stuff, so recommended retail is almost immoral. No wonder they can have their 50% off sales. They are STILL making a huge profit.

So, having said that, any official valuation that you have done on jewellery isn't worth the paper it's written on except if you are making an insurance claim.

One example, I bought a gemstones actually an amethyst, took it to a very reputable jewellery store for a valuation - paid $95 for the valuation from memory. The certificate says $2,000 - guess what I paid for it? $80. I told the valuer this and he said, Yes, that's about right for wholesale.

Let's take our engagement ring - 45 years ago I paid $35 at a recognised wholesaler. S had it valued the next day at $500.
