A simple, tiny Thomsonite and Basalt pendant; such a beautiful contrast. Wear it everyday to remind you of the unique and rugged North Shore of Lake Superior.
Basalt is by far the most common rocks you will find on Lake Superior’s North Shore beaches. It is one of the four rock-types that make up the basement bedrock of the earth’s crust. Basically it is lava that cooled quickly on the surface. Each one has a distinctive shape and in a variety of shades of color from blush-black to grey. That quick cooling is what caused it to be dense, very fine grained (tiny crystals) and smooth – although the smooth surface is also due to glacial grinding & Gitche Gumee tossing it about for eons. That Basalt rock you hold in your hand (or wear on your body) is over a billion years old!
Thomsonite is a very unique stone only found on a small 6-mile stretch of beach on the North Shore of Lake Superior in Minnesota. Thomsonite is formed like agates through water percolation into petrified bubbles in the basalt. Thomsonite is much rarer than an agate. It is even considered a semiprecious stone by some. Look for an “iris” of pale green and radiating circles or “veins” of pink.
