I just wanted everyone to know what a true professional Martin Sheffield from usacerteddiamonds.com is! I purchased a beautiful 1.04 AGS 000 Princess cut from him last week and he helped me every step of the way. It was a true pleasure doing business with him and I would HIGHLY recommend him to anyone interested in buying a diamond. His price was unbeatable and I checked high and low for weeks. I just had the diamond appraised by D atlas and Co. in Philly today and it was valued at more than double the price I paid. In the very confusing world of purchasing a diamond martin made it easy and enjoyable. Thanks again and keep up the great work. Sean Millard
