Dear Lifehacker, I was wondering if you can help me appraise some gold stud earrings I wish to sell? They're jadelite cream with a vintage apple design.

If you've chosen to shop online for a ring either because you want something hand-crafted from a unique material, or you just dislike jewellery stores, you'll still need to know the right ring size before you buy. Grab a roll of scotch tape and this handy ring sizing chart from Blue Nile to get a good idea of what size you should buy.
