Quartz of Wintertide captures the bold, cloudy turquoise that appears only when Lake Michigan is at her coldest. This isn’t a summer sky kind of blue—it’s softer, scattered, touched by the suspended quartz dust stirred up by the lake’s winter churn.

For millennia, quartz stones have been grinding against each other in these waters—first by glacier, now by wave. What began in ice continues in motion, a slow wearing down that leaves just enough crystal present to scatter the light.

The result is this rare color we glimpse only in deep winter: bright but quiet, bold but blurred at the edges. Like the lake itself, when it’s both restless and still.
