Pair of Queen Conch Shells (Aliger gigas)

This is a set of two large, natural Queen Conch (Aliger gigas, formerly Strombus gigas) marine gastropod shells. The specimens exhibit characteristic heavy, calcified structures with prominent spiral spires and flared, wing-like outer lips. The shell on the left is larger and significantly more weathered, displaying a chalky white finish with visible 'crazing' or surface hairline fractures, suggesting long-term exposure to sun or sand-bleaching which has stripped the periostracum and original pink nacreous finish. The shell on the right is smaller and retains more natural coloration, featuring a creamy-beige exterior with visible growth lines and darker ridge highlights. Both shells feature robust, blunt spines on the shoulder. Notable condition issues include erosion to the pointed tips, minor chipping along the delicate edges of the flared lips, and significant surface dulling on the larger specimen. These are natural organic objects rather than manufactured goods, though they are commonly used as decorative arts or nautical collectibles. Their size and heavy calcification indicate they were likely harvested as mature adults. Based on the degree of weathering, they appear to be older vintage finds rather than fresh specimens. There are no visible maker's marks, as these are natural biological specimens.
