New: Lake Superior agates, vibrant new finds from Malawi & our latest video
In this week’s shop update, everything revolves around genuine classics from the US and brilliant, colorful displays from Africa!
Main Focus: The Fascination of Lake Superior Agates
The Lake Superior agate is considered a true treasure of North American geology among mineral collectors. Formed over a billion years ago in the volcanic rift system of Lake Superior, these pieces were transported hundreds of kilometers and naturally tumbled by massive glaciers during the last ice age.
Because of this natural ice-age tumbling, their exteriors are smoothly polished by nature itself, which is why many collectors choose to display them in their original, uncut form.
These agates owe their characteristic range of colors to the exceptionally high iron content present during their formation, glowing in deep reds, radiant oranges, and warm browns. An absolute eye-catcher is the fine fortification banding: the sharp, often fortress-like patterns create a fascinating contrast between snow-white or transparent quartz and fiery chalcedony. Due to their multi-million-year journey through glacial ice, these pieces also feature an extraordinarily dense and fine quartz crystallization, revealing an unmatched luster after polishing.
