Our Story
For some families, summer vacation meant crowded beaches or theme parks. For ours, it meant dusty boots, wide-open plains, and scouring the rugged landscapes of South Dakota and Nebraska with our eyes glued to the ground.
Welcome to Superagates.com. This business is, first and foremost, a family passion project between a father and two sons that has been four decades in the making.Â
Mark has been an avid rockhound and agate collector for over 40 years. Throughout the years, he’s developed a wealth of expertise and relationships within the rock collecting community. Â More recently, he’s found joy in sharing his experience through YouTube.
Sons Brian and Jason grew up surrounded by rocks and the hum of rock tumblers in the basement. Â As both grew older, they eventually traded rock hammers for laptops, building corporate careers rooted in technology and supply chain management. Superagates now provides an opportunity to spend more time together as a family while we work to spread the hobby that brings us so much joy.
Bridging the Old School
and the New
Recently, we realized we had a unique opportunity. We wanted to create a space that honored Mark’s incredible, hard-earned expertise while bringing a seamless, modern experience to the rock-collecting community.
Superagates.com is the convergence of those two worlds. Mark handles the curation, bringing a lifetime of knowledge to carefully select, identify, and grade every piece. Jason and Brian handle the operations behind the scenes, ensuring that the technology works, the shipping is rock-solid, and your experience is flawless.
Our Philosophy We built this shop as a passion project to keep our family connected to the hobby we love, and to share a lifetime of discoveries with people who appreciate them just as much as we do.
We aren’t here just to move inventory; we are here to share a legacy. Whether you are hunting for your very first agate or searching for the crown jewel of your display cabinet, we are thrilled to share a piece of our family’s passion with yours.
Giving the best value
to our customer
As lifelong rockhounds, we know what it’s like to be on the buying end of the hobby. We’ve experienced the thrill of tracking down the perfect piece, and we’ve also felt the frustration of opening a package that didn’t live up to its online photos.
Our approach to value is simple: we treat fellow collectors exactly how we want to be treated.
What You See Is Exactly What You Get: When you are buying a unique piece, “similar to the photo” simply doesn’t cut it. Our photography captures the true color, banding, and texture of every agate. The agate you fall in love with on your screen is the exact stone that shows up at your door. No surprises, no substitutions—just honest representation.
For Every Collector, At Every Level: The joy of collecting shouldn’t be gated by a massive budget. Whether you are a beginner looking for a beautiful, affordable tumbling rough or a seasoned expert hunting for a rare, display-case centerpiece, we purposefully curate our inventory to offer exceptional agates at every price point.
Relationships Over Transactions: We aren’t here to make a quick sale and move on. We want to hear about your latest finds, help you source that elusive missing piece, and be a trusted resource for you as your collection grows.
Our greatest reward is knowing that a piece our family hand-selected has found a permanent, appreciated home in your collection.
