Kay jewelers are one of the best in the business. They bring you all kinds of jewelry items in one place. They have got 900+ stores. They run clearance sales from time to time where you can get jewelry items at 30% - 50% discounts. There a section called "Education Center" on the website where you can learn about jewelry related things. You can also find lots of used but quality old jewelry at Kay Jewelers. Again they provide you with 1-800-527-8029 kind of customer service. I think its worth giving try.
