# Crown

> A stylized golden king’s crown with a flared band, piped rims, pointed tines topped with pearls and alternating inset gems, centered on the origin for floating pickups. About 0.26 m across. Adjust the number of points, gold and gem colors, or add a red velvet cap for a royal throne-room prop, treasure reward or high-score trophy.
