His unique store has made several transitions over the years and today enjoys a modest setting with extremely low overhead which translates to clients in the form of being able to provide wonderful high quality stones and heirloom quality jewelry at a fraction of a traditional retailer. Over the years, Wink has become a respected expert nationally in evaluating the quality of diamond cutting and more importantly, in being able to explain it in an easy to understand and interesting way. He loves sharing his knowledge and his first love of extraordinary colored stones continues to this day. Wink has an incredible collection of Award Winning gemstones as well as access to exceptional gems of many hard to find specimens and extraordinarily beautiful cut diamonds.Most recently Wink has enjoyed assembling a team of expert studio artists who work with him and some even with each other.

He also partners with some of America”™s finest studio artisans to create fabulous custom pieces to make his clients”™ hearts sing. Wink takes great joy in working with people to create heirloom quality jewelry that will be enjoyed for generations.
