I have a couple of Tiffany necklaces (one color by the yard and one diamond by the yard) in 18k yellow gold that I would like to sell. I just got a quote from Fashionphile and the price they offered was much lower than I expected. I was wondering where you sell the Tiffany pieces you no longer want? There is a consignment place I use for selling designer bags but unfortunately they don't sell luxury jewelries. I have listed both items on facebook marketplace but I doubt I will get any serious offer. Any advice would be appreciated.
