When listing in Antiques & Vintage, I do not see sub categories for bracelets, pins, earrings, etc. How can I be sure my jewelry will go in the correct categories if I can only highlight Antiques & Vintage? I'm confused! Your help is appreciated!

Are you listing in the jewelry category and antique subcategory? There is not a subcategory for jewelry in the antiques category. It has to be put in the jewelry category. Then you can put it in the antiques subcategory or in the pins and brooches, bracelet, or whatever subcategory.
If you put jewelry in the antiques category, it will be moved or flagged. One piece the moderator will probably move-a bunch, she will flag and your store will be suspended until it is fixed.

I'm listing in the sub categories below Jewelry & Watches. I just wanted to be sure. Thanks for your help.

I know it's not a very good option. I have sold jewelry for years and done well at it. But vintage jewelry is a lost cause at Ecrater because of the categories as well as all the competition. I finally gave up and quit buying jewelry.

You're probably right about that. I do not expect any of the venues to draw as many buyers as Ebay does, but, I need to try. I noticed there are categories missing for jewelry, such as designer signed, necklace sets, bracelet sets, parures, pin sets etc. I know if I were looking to buy something in these categories, and cannot find them listed, I would look elsewhere on another site. The success of Ebay drawing buyers to them are their comprehensive sub categories, which brings buyers directly to the sellers that are offering what they want. I like the look of Ecrater, but time will tell if it will work for me, and thanks for your input.
