A collection of gemstones and minerals arranged in a grid displays nature's crystalline forms in jewel tones of ruby red, emerald green, sapphire blue, and deep burgundy against a pale cream background. The watercolor and ink technique captures each stone with precise botanical detail, revealing the translucent depths and faceted surfaces that define precious gems. 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.
