Story
BSK was a New York-based costume jewelry company founded in 1948 by Benny Steinberg, Slovitt, and Kaslo. They produced affordable, stylish costume jewelry through the 1970s, often featuring brushed or textured metals, rhinestones, and faux pearls. While they are famous for their 'My Fair Lady' collection, this floral piece represents their standard, everyday mid-century botanical lines.

Market Analysis
The secondary market for mid-century costume jewelry (such as BSK, Trifari, and Coro) is highly saturated but maintains steady demand among vintage fashion enthusiasts. Buyers typically source these pieces on Etsy, eBay, and Poshmark. Prices are generally modest unless the piece features rare rhinestones, complex enamel work, or is part of a complete parure (set). Simple brushed metal pieces move reliably at the lower end of this spectrum.
Value Drivers
▲ Brushed silver-tone floral design aligns perfectly with popular mid-century modern costume jewelry trends.
▲ Attribution to BSK, a recognized mid-century maker, elevates the piece above unmarked generic costume jewelry.
▲ Etsy and eBay comps for similar brushed metal BSK brooches establish a reliable $15-$20 baseline.
Concerns
▼ Unverified maker's mark — a missing 'BSK' stamp would drop the estimate into unbranded territory.
▼ Unverified clasp condition — a broken or missing pin stem would severely reduce wearable value.
▼ Lack of accompanying earrings or matching pieces limits the set-premium potential.
Best Venue
List on a vintage-friendly platform like Etsy or eBay. A fast-sale price of $12-$15 is recommended to move the item quickly, while an optimistic list price of $20-$25 could be achieved with excellent, well-lit photographs. Ensure a clear photo of the 'BSK' hallmark and the working clasp is added to the listing to justify the branded price point.
Upside Potential
If matching clip-on earrings are located to form a complete demi-parure, or if the piece can be definitively linked to a specific, highly collected BSK designer line, the value could push toward the $40-$50 range on a curated platform.
