Oxidized or darkened sterling silver abstract sculptural heart-shaped brooch or pin accented with small clear rhinestones or crystals.

The dark coloration is an intentional chemical oxidized or blackened finish designed to give the sterling silver an antique, high-contrast look that makes the bright rhinestones pop. Pieces with this twig-like, free-form wirework aesthetic are often classified as modernist or brutalist artisan jewelry from the mid-to-late 20th century.

The estimated resale market value of this 925 sterling silver artisan brooch is $25 to $55 under typical secondary market conditions.

Design Appeal: The value rests primarily in its aesthetic appeal as a modernist or brutalist wirework piece.

Maker's Mark Premium: Unsigned artisan silver pins generally sell on the lower end of the spectrum ($25–$35). However, if you examine the back and locate a known studio hallmark or signature alongside the "925" stamp, the value can easily reach $60 to $120+ depending on the designer's collectibility
