These Chocolate Calcite bookends, measuring 8 inches tall by 6 inches wide and weighing 12 pounds, are both functional and striking. Made from Chocolate Calcite—a calcium carbonate stone with a Mohs hardness of 3—they boast a deep brown color with natural tan or white banding, polished to highlight their unique patterns. Formed in sedimentary limestone deposits, often from Pakistan or Mexico, their 12-pound weight ensures sturdy book support. Tied to the Root Chakra, they’re said to offer grounding and calming energy, making them a perfect blend of practicality and natural elegance for any shelf or desk.
