Had a long pleasant conversation with Mark (owner of Landmark Diamonds and Precious Metals) when I was calling shops around to sell some items. He is very knowledgeable, and a wise man whos knows ins and outs of this industry. He was upfront, and honest and also gave me some valuable advice which will help appreciate the value of my belongings. Will continue to stay in business with him...

Have had dealings with Mark Heiligman and he is a pleasure. Very honest and authentic. Thank you Mark!Cynthia Strom

Great experience, knowledgeable, helpful. Will continue to do business.
