🪙 Introducing: The Cranky Coin Guy Show

If you haven’t met David yet, he’s our in-house Cranky Coin Guy—but coins are just the beginning. He’s also a pocket watch expert, history buff, and basically a walking encyclopedia of really cool old stuff. 😂

He knows his stuff, he’s not afraid to say it like it is, and we love him for it.

What should David get cranky about next? 👀 Drop your questions or topics below!

Happy 1 Year to Rick! 💎🥳

Rick is our Diamontologist & Jewelry Specialist, but he definitely wears a lot of hats around here. From diamonds and jewelry to tackling inventory and making sure everything behind the scenes runs smoothly and actually makes sense 😂—he’s always on it.

But what really stands out is how much he cares about our clients. Rick is always making sure people feel taken care of, informed, and leave happy.

We’re so lucky to have him on the Blue Diamond team. Happy one year, Rick! 💙💎
