Pearl Necklace and Earring Set with Identification Report

This item is an official 'Pearl Identification Report' issued by an unnamed laboratory (abbreviated as 'IDE, DIAMOND & JEWELRY LABORATORY' based on the logo). The report features an image of a matching pearl necklace and earring set. The necklace is composed of numerous uniformly sized, round to near-round pearls, strung together, and appears to have a decorative clasp, possibly silver-toned or white gold, in a floral or intricate knot design. The accompanying earrings are stud-style, each featuring a single pearl that matches the necklace in size and luster, with what appear to be simple post backings. The pearls themselves exhibit a silver-pink overtone and are described as '不透明' (opaque), indicating they are natural pearls with good nacre. The size specifications are clearly listed, with the necklace pearls ranging approximately from 6.5mm to 7.0mm in diameter, and the earring pearls being uniformly 6.6mm in diameter. The overall appearance suggests a classic and elegant pearl set, likely of cultured origin given the uniformity, though the report simply states '真珠' (pearls). The craftsmanship of the stringing appears consistent, suggesting a professionally curated set. The report itself has a unique identification number 'PA 05308', dating it to a specific period of issuance, likely in the mid to late 20th century or early 21st century based on the document's design and OCR identified text "LINE". There are no visible condition issues with the pearls or settings from the image, but the quality of the report printing could be improved in terms of clarity.
