Hello, this item is a large Southeast Asian Buddha sculpture, most likely originating from Burma, present-day Myanmar, and produced in the 19th to early 20th century rather than the 18th century. The figure is shown in the bhumisparsha mudra, with the right hand touching the earth, a gesture associated with the moment of enlightenment of Gautama Buddha. The elongated proportions, smooth facial features, and the stylized flame-like finial on the ushnisha are characteristic of Burmese Mandalay-style imagery. The material appears to be wood or composite with lacquer and gilt decoration, now heavily worn, which is consistent with traditional Burmese lacquer techniques. However, the surface wear, uniform patina, and construction details suggest a later decorative or devotional piece rather than a true 18th century temple sculpture. The scale is impressive, but the carving lacks the refinement and depth expected in earlier period examples.

From a market perspective, large Burmese Buddha figures remain desirable, but value depends heavily on age, craftsmanship, and originality of surface. Given the likely 19th to early 20th century date, visible wear, and some damage to the headpiece, this piece falls within the decorative and mid-tier collector market rather than the high-end antiquities segment. Comparable works of similar size and quality typically achieve between $2,000 and $5,000 USD at auction.
