The best way to see what appeals to you is to get out there and experience the pieces for yourself. Head to the stores, walk the counters, try things on, and get a feel for what you like or don't like. Buying jewelry is a personal experience and you should take as long as you like. Inspect the piece for quality, do your homework, and ask questions.
