We're family-owned and operated, and we take pride in our friendly service and quality products. We specialize in fine-make GIA round and fancies (including cushions, ovals, and emeralds). We are a premier supplier of GIA 3EX and Hearts & Arrows, and we sell more than paper. We, personally, “cherry-pick” each and every stone.

Honored and grateful to be recognized by Jewelers of America as part of its 20 Under 40.

As a teenager, my summer job was helping my parents around the office. Over time, that turned into a beautiful career in an industry I’ve come to truly love.

Thank you to my family, friends, clients, mentors, and peers who have encouraged me and shaped my path along the way.

Thank you to Jewelers of America for the recognition.

Giving back is a core value at Union Gems, and it’s possible because of you, our friends and partners.

Why're we Union Gems? In 1982, Hans believed good business is a 'union' or partnership. This is our core belief, even today.
