Union Gems

Excited to share — I'll be speaking at AGS Conclave this September! 💎

📅 Tuesday, September 15 | 10:30–11:30am EDT
🎤 The New Diamond Horizon: Merchandising & Profit in a K-Shaped World

The diamond category is changing fast. De Beers. Lab-grown. A consumer market splitting in two.

My session cuts through the noise and gives AGS retailers a practical playbook: what to stock, how to merchandise, and how to protect your margins.

If you're attending Conclave, I'd love to see you in the room. Link in bio to add it to your schedule.

At Union Gems, giving back isn't a campaign — it's a value.

We're proud to support NAMI (National Alliance on Mental Illness) and the vital work they do helping individuals and families affected by mental illness find community, education, and hope.

Mental health touches every one of us — our customers, our partners, our families. A healthy, safe, and supported society is the kind of world we want to be part of building.

42 years ago, Hans started Union Gems from scratch.

40 years ago, he had his first kid. (That's me, GK.)

Over the decades, he's worn every title this business has to offer — founder, CEO, buyer. He's been good at all of them.

But the roles I think about most aren't on any business card.

Friend. Mentor. Father.

Happy Father's Day, Dad.

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.
