You really need to do better with your descriptions and put up pictures. If you don't have a camera, you can get a little digital, about 4" square, that fits your keychain. They work fine for Listia. I think they hold about 20 pictures. Don't know where you live, but near me they run around $10 and are well worth it. Plus, if it's on your keychain, you'll have a camera at those moments you want to remember, but no camera!
On jewelry, try to tell the brand, length or size, color, metal purity, meaning is it real 925 or 928 silver, sterling silver, silver plated, gold, gp = gold plated, There's also gold over silver, vermiel, base metal, etc. Post any markings that are on it. The more you say about it, the more bids you'll get!
