Overview
The brooch features faceted black glass stones in a dark, japanned metal openwork setting, characteristic of mid-20th-century Victorian Revival costume jewelry. The presence of a standard rollover safety clasp on the reverse supports a mid-century dating (c. 1940s-1970s).
Story
This style reflects the mid-20th-century (c. 1940s-1970s) resurgence of Victorian mourning aesthetics. Costume jewelry manufacturers frequently used 'French jet' (black glass) and japanned (blackened) base metals to simulate the look of antique jet or onyx. Without a maker's mark, this piece is attributed to the broader mid-century costume jewelry manufacturing boom, likely produced for department store retail.

Condition & Value
Value relies heavily on the integrity of the glass stones (no chips or flea bites) and the japanned finish (no flaking or rust). The rollover safety clasp must be fully functional. Pending clear macro photos, the current valuation assumes all stones are present and original, and the metalwork is structurally sound.
