An excellent and aesthetic specimen of Pyrite from the renowned locality of Navajún, La Rioja, Spain. It features a compelling group of four beautifully intergrown cubic crystals with razor-sharp edges and a superb metallic luster. The complex, geometric intergrowth of the crystals—where three appear naturally connected—creates significant visual interest and is highly prized. The specimen displays excellent quality and stands perfectly on its own, making it a choice piece for any collection focused on crystallography or aesthetic minerals. Condition is as shown in the photographs. As is common with delicate specimens from Navajún, minor professional reattachment may be present to preserve the specimen's integrity.
