How Are You Launching Your New Jewelry Pieces?

How were you launching your new jewelry pieces? Did you just put them up and they started to sell because you did good homework or did you have a list or a marketing method how are you doing that. I don't launch very high I even go like lower but I will add one dollar every day and when I launch them if they don't sell the next day I will change listing. If it's not in this speed I will also check what is wrong with the listing.
