Competition online is tough for fine jewelry sales; while many items made with precious
metals and gems do sell, they often go for far less than retail. This is partly
due to the increased supply; many jewelry stores and manufacturers use online marketplaces
to clear out last season’s leftovers at bargain prices. Still, there is a market
for well-known designers like those in the list below.
Designer jewelry is frequently counterfeited; in 2004 Tiffany & Co. estimated that
nearly 75% of all the Tiffany items sold on eBay were counterfeit. Many high-end
jewelry designers actively enforce their copyrights; therefore it’s important to
include proof of authenticity in your listing.
Ask the owner when and where they acquired the jewelry. Some sellers will include
a sales receipt (with personal information blacked out) with the item as proof of
authenticity. Clear photographs of the item will also help. In particular, take
close-ups of any hallmarks, stamps, logos or other markings.
Visit each designer’s website for photos and descriptions of their current catalogues.
For older collections, try Powell’s Books (http://www.powells.com)
or your library for the following out of print titles: Hughes,

Look for these signs of wear and tear:
Damage will be easier to spot with a jeweler’s loupe or magnifying glass. If the
item is particularly dirty, suggest to the owner that they clean the item or take
it to a jeweler to be cleaned (don’t clean it yourself).
Use the original packaging whenever possible to store and ship an item. Otherwise,
wrap the jewelry in bubble wrap and cushion with crumpled tissue paper or packing
peanuts. Padded envelopes and poly mailers won’t prevent the items from being crushed,
so use a sturdy box. Expensive items should be insured and shipped with tracking.
