Ralph Mueller and Associates are a most ethical, capable, and inviting company to work with. The personnel are knowledgable, friendly, and most willing to help people understand the business of buying and selling diamonds. I've completed 2 transactions with this company and cannot tell you how comfortable and at ease I felt throughout the entire transaction process. I highly recommend this company to anyone who is in the market to buy or sell diamonds.
