Chinese-style carved stone cup set in display box

This set consists of two small, footed cups seated within a padded display box. The cups appear to be crafted from a translucent dark green mineral, stylistically consistent with nephrite jade or serpentine, often referred to as 'luminous stone' or 'Jiuquan jade' in a Chinese cultural context. The stone features characteristic dark inclusions and mottled veining. The cups have a smooth, polished finish with a slightly flared rim and a tiered or ribbed exterior design toward the base. They are nested in a yellow silk-like fabric lining within a rectangular hardwood or dark-stained wood box with a hinged lid and a simple brass-toned clasp. The interior of the lid features a printed image of a Chinese architectural site, likely a commemorative landscape, accompanied by vertical columns of Chinese calligraphy. The text appears to be decorative or poetic in nature, though without physical inspection, its exact provenance cannot be determined. The construction suggests a mid-to-late 20th-century souvenir or gift item. No specific brand marks are visible; the attribution is based on the visual aesthetic and the traditional association of such dark green stone cups with Jiuquan, China. The condition appears to be excellent, with the stone retaining a high polish and no visible chips or cracks in the photograph.

Based on the photograph provided, I have examined this set of two dark green stone cups in a silk-lined presentation box. The cups appear consistent in color and texture with 'luminous stone' or Jiuquan jade, which is often a variety of serpentine or nephrite. However, I cannot verify the exact mineral composition from a photo; a physical inspection using a hardness test and specific gravity measurement would be necessary to distinguish between high-grade jade and more common soft stone minerals. The set features a commemorative landscape and calligraphy inside the lid, suggesting it is a mid-to-late 20th-century gift or souvenir item. The value estimate is Based on the assumption that these are functional decorative items in excellent condition with no visible chips or cracks. The market demand for such souvenir sets is generally stable but modest, as they were produced in significant quantities. My estimate reflects the typical retail or secondary market range for sets of this type. If the stone were identified through scientific testing as a rare, high-quality nephrite, the value could increase slightly; conversely, if the material is found to be a dyed composite or glass, the value would likely fall below $20.00. To confirm the origin and material, an in-person examination by a gemologist or a specialist in Chinese decorative arts would be required, as photos cannot replicate the tactile feel or light transmission properties of the stone.
