Hello, this item is a small carved stone cup in the style of Chinese jade vessels, likely produced in the 20th century rather than being an earlier antique example. The form, with its flared rim, rounded body, and stepped foot, loosely references archaistic ritual shapes seen in Chinese bronzes and later jade carvings. However, the surface shows uneven coloration with brown and whitish patches that appear more consistent with staining, chemical treatment, or lower grade stone rather than natural jade patination developed over centuries. The carving is relatively soft in definition and lacks the precision and refinement expected in Qing dynasty or earlier jade workmanship, suggesting a decorative or souvenir piece made for the export market.

From a market perspective, small decorative jade or jade like cups of this type are widely produced and their value depends heavily on confirmed material, whether nephrite or jadeite, and on craftsmanship quality. Without gemological testing to confirm true jade and given the modest carving quality and size at approximately 6 cm, the fair market value is estimated at $50 to $120 USD.
