Two polished agate slices reveal concentric rings of coral, orange, amber, and cream, with deep burgundy edges and glowing yellow centers that suggest geothermal heat. The composition captures the raw geological beauty of these mineral cross-sections, arranged vertically with organic precision against a clean white ground. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
