There is obvious white calcification on the outer surface, from aging I believe.

Hello, this item is a small carved stone figure in the style of Chinese erotic or “bedroom” carvings, depicting three intertwined human figures in a copulating scene. Despite being described as jade, the material does not show the density, translucency, or fine polish expected of nephrite or jadeite. Instead, the surface appears granular and matte with uneven coloration and artificial-looking white encrustations, which are more consistent with soapstone or a low-grade hardstone that has been chemically treated to simulate age. The carving itself is relatively soft in detail, with simplified anatomy and rounded forms, indicating a decorative production rather than a finely worked scholarly or imperial object. Pieces of this type are often produced in the 20th century for the export or tourist market, drawing loosely on earlier Chinese erotic art traditions.
From a market perspective, genuine antique jade erotic carvings are rare and can be highly valuable, but examples in substitute stone such as this are common and primarily decorative. The perceived “calcification” is not a reliable indicator of age and is frequently artificially induced to enhance visual appeal. Comparable pieces typically sell in the range of $50 to $150 USD depending on size and presentation.
