Copper crystals are one of the most fascinating natural metallic formations found in the mineral world. Their twisting, branching shapes almost look sculpted by hand.

Michigan has a rich history tied to copper mining, making specimens like these especially meaningful to collectors across our state.

Pearls are June’s Mineral of the Month 🤍

Unlike most gemstones formed deep within the earth, pearls are created inside living oysters and mollusks, making them one of the few organic gemstones in the world.
Their soft glow and timeless beauty have made pearls symbols of wisdom, elegance, and rarity for centuries. No two pearls are exactly alike, which makes every piece uniquely beautiful.

Nature has a fascinating way of turning something small into something extraordinary.

Emeralds: A Timeless Favorite
There’s a reason emeralds never go out of style. That deep green color has been turning heads for centuries, symbolizing growth, renewal, and a connection to the natural world.
Even if you’re collecting closer to home, the love of gemstones starts the same way, curiosity, discovery, and that moment you realize you’ve been staring at a rock for five minutes straight.
No judgment here.

Quartz is one of the most abundant minerals on Earth, but don’t let that fool you, it’s anything but boring.

From clear crystal quartz to smoky, rose, and amethyst varieties, this mineral shows up in more forms than most of us can keep track of.

It’s also the star of our upcoming show this October… because if you’re going to celebrate something, it might as well be the overachiever of the mineral world.
