Silver-Tone Pearl Brooch by Illinois Pearl Tokyo

This is a vintage silver-tone brooch featuring a single, white spherical pearl. The brooch has an elegant, mid-century modern design, approximately 1.5 inches in length as per the context. It consists of multiple curved and flowing lines, likely made of metal (possibly sterling silver or a silver-plated base metal), which converge to cradle the central pearl. The pearl appears to be a cultured pearl, exhibiting a good luster and a relatively smooth surface without significant blemishes visible in the image. The metalwork displays a polished finish, reflecting light, and its construction suggests a delicate yet sturdy form. The back features a standard pin clasp mechanism, typical for brooches of its era. No overt damage such as bends, breaks, or significant tarnishing is visible, indicating good preservation. The brooch is presented in a deep purple velvet-lined box with a white satin interior lid. The lid bears a black printed logo which reads "ILLINOIS PEARL TOKYO JAPAN GINZA 03-574-7824", suggesting the original retailer or manufacturer and its location in Japan. This branding is a key distinguishing feature and points to the item's origin and potential age, likely mid-20th century given the style and telephone number format. The craftsmanship appears to be of good quality, typical of mass-produced yet well-designed jewelry from that period, with attention paid to the symmetrical placement of the pearl within the flowing metal lines.
