June 15 – Hidden Gems of Lake Superior

Lake Superior agates, the rare gems of the inland seas, are renowned for their distinctive red, orange, and yellow banding. Their beauty and uniqueness have made them some of the most treasured gemstones of the Northland.

People find Lake Superior agates along the shores of Lake Superior and in surrounding gravel pits across the Northland. Agates are a form of chalcedony that formed millions of years ago in cavities within volcanic rock. Over time, mineral-rich water deposited layers of silica and iron, creating the beautiful banding patterns we see today.

Unlike many gemstones, agates can be found by anyone willing to walk a shoreline, search a gravel pit, or keep their eyes on the ground. Many agates have a rough, weathered outer surface, but when cut or polished, they reveal their hidden beauty.

“The foundations of the city walls were decorated with every kind of precious stone. The first foundation was jasper, the second sapphire, the third agate, the fourth emerald.” — Revelation 21:19

Agates show us that great beauty often lies beneath rough surfaces. Sometimes, a little time, pressure, and polishing reveal something far more beautiful than we first imagined.
