Layered bands of deep navy and slate blue undulate across the composition, separated by luminous gold veins that trace the natural fractures of agate. The organic wave-like striations suggest the cross-section of a geode, where precious minerals have crystallized over millennia, creating a jewel-like surface that feels both geological and ethereal. 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.
