Pair of decorative stone bonsai trees in the Chinese export style

A pair of decorative tabletop displays, stylistically consistent with 20th-century Chinese export 'stone bonsai' or flower sculptures. Each piece features a wire-wrapped trunk and branches covered in green thread, supporting leaves and petals that appear to be crafted from carved semi-precious stones or glass, possibly including varieties consistent with carnelian, rose quartz, and dark jade or nephrite style hardstones. Each flower is centered with yellow bead stamen. The trees are set into square, pale celadon-colored planters that appear to be carved from a light-colored hardstone or alabaster, with the surface filled with small crushed stone aggregate. The craftsmanship shows manual assembly, with individual petals and leaves wired into place. There are no visible maker's marks, signatures, or labels in the image to provide a specific manufacturing origin. The identification is based entirely on aesthetic and construction features commonly found in mid-to-late 20th-century decorative imports. Some slight misalignment of petals and leaves is visible, consistent with use or handling over time.

I have examined the provided images of this pair of decorative stone bonsai trees. Based on the visual evidence, these pieces appear to be mid-to-late 20th-century Chinese export-style decorative arts. The assembly, featuring wire-wrapped branches and carved hardstone or glass petals, is characteristic of mass-marketed luxury imports from this era. I can observe what appears to be carnelian and quartz-like materials, though I cannot verify the specific mineral composition or the hardness of the stones without a physical scratch test or gemological inspection. From the photos, the pale celadon-style planters appear to be carved soapstone or alabaster, but I cannot confirm if they are natural stone or a composite material. The value estimate of $150 to $300 assumes the materials are genuine semi-precious hardstones rather than molded glass. If these were determined to be modern plastic or cast resin reproductions, the market value would likely drop below $50. Conversely, if the materials were confirmed as high-quality jadeite or nephrite, the value could exceed the current estimate. There is a steady decorative market for these items, though they are often subject to condition issues like loose wiring or chipped petals. I can see some slight misalignment in the leaves, which is typical for items of this age. To establish a more precise valuation, an in-person examination would be required to check for hidden maker’s marks, assess the weight and coldness of the stones, and verify the structural integrity of the thread-wrapped armatures.
