I was nervous to sell gold as it was my first time. Mary was very professional and explained to me all the different qualities of gold while she tested my gold. She also is very knowledgeable about gemstones. She needed to take a stone out of one of my rings and promised to mail it back to me. I was a bit leery of allowing a stranger take an heirloom diamond and mail it back. However, within days I received a text that my diamond was in the mail. Mary did a great job and I felt I was paid fairly for what I turned in I loved the fact that I walked out with a check that surpassed my expectations. I highly recommend Valley Goldmine!
