Sigh. Rats.
~First thing to to do is take photos of the necklace on a white background, not shiny. A white paper towel, or sheet or handkerchief.
~make sure to show a photo of the clasp
~try to photograph in the middle of the day, in the shade if it's very sunny
~still include one photo on the black background
~the ad you craft should mention PP, Freshadama, 7.5-8mm white necklace, 18inches, yg (for yellow gold) or wg (for white gold) clasp
~indicate if you still have the box and the appraisal
~note if shipping is included in the price
Thomas, I have a son who was broken-hearted or broken up with 3 times before he met his wife. I couldn't kill all of them.....
I'm sorry for your dashed hopes, and hope you're mending well.
In general, one loses money reselling jewelry. I can only tell you that items up for resale with the tags Pearl Paradise and Sea of Cortez, do pretty well. The names carry confidence with them.
I've only bought used, not sold anything. There are 3 sites I know off the top of my head, if you want to use a website (I'm skipping eBayUK and Craig's List but you could do them, too).
DiamondBistro,
LoupeTroupe,
PriceScope
Diamond bistro and loupe troupe are the easiest sites for buyers/users to find pearls on.
