Polished Banded Agate Geode Slice Bookend Appraisal

Polished Banded Agate Geode Slice Bookend

This item is a single bookend crafted from a natural geode slice, likely origin of Brazilian agate. The piece features a semi-circular profile where the interior has been cut flat and polished to a high-gloss finish, while the outer circumference retains its natural, rough host rock rind. The interior showcases characteristic concentric banding transitions from outer rings of translucent white and grey into a central core of milky white to pale amber-colored micro-crystalline quartz. The specimen displays a faint, naturally occurring internal fracture line running vertically near the center, which is typical for these geological formations. The overall condition appears excellent with a smooth, reflective face and no significant chipping on the sharp edges. Its construction is heavy and dense, providing the necessary weight to support books. The craftsmanship is evident in the precision of the cut and the clarity of the polish, highlighting the natural aesthetic of the gemstone. While not signed, this style of lapidary decor was highly popular from the 1970s through the modern day, often used as a sculptural accent in mid-century or contemporary interiors.
