Thank you for submitting your item for appraisal. This appears to be a chinese Prehnite carving of a lotus leaf with fish below, chemically treated with green oil. The shiny surface and the brown residue in the grooves are an indication that this not a genuine piece of jadeite but rather heated and oiled Prehnite. Similar decorative stone carvings sell in the price range listed. There is no measurement for the sentimental value you might attach to the item.
