Isle Royale Treasures

Isle Royale Treasures FREE shipping within the United States! Isle Royale Greenstone

One of the rarest gemstones in the world and one of the most valuable American gemstones.

Our mission is to create Michigan's finest quality Isle Royale Greenstone Jewelry.

*All of our genuine Isle Royale greenstones were purchased in the rough from a certified pre-1915 estate collection. Just like diamonds, Greenstones formed in ancient lava flows one billion years ago. Greenstones are more rare than diamonds but not nearly as costly in comparison. Chlorastrolite has been discovered

in only one geological area in the world. Isle Royale Greenstones are the most prized for their beauty by museums and collectors. Isle Royale later became a national park in 1940, so from that date forward it is illegal to collect greenstones from the island & its beaches. The gems featured in this limited collection were sourced from an estate of a long-ago treasure hunter, who had collected them on the beaches of Isle Royale prior to 1915. Petoskey stone which is a fossil is known as the Michigan state stone, but in 1974, Greenstone became the official state Gemstone.

If Isle Royale Greenstone were the Met Gala theme… ✨

The red carpet would turn into a tribute to nature’s finest design—deep forest greens, luminous mosaic patterns, and textures inspired by Michigan’s rare Chlorastrolite.

At Isle Royale Treasures, that vision isn’t just inspiration, it’s something you can actually wear. 💚

Own a piece of nature. Wear a story.
