Overview
The photographs show a guitar-shaped brooch with blue enamel, applied twisted-wire strings, an openwork filigree back, and a hinged pin with a safety catch. The visible 900 stamp supports identification as nominal 90% silver, although metal purity has not been tested.
Story
The item is consistent with 20th-century decorative silver filigree jewelry, but its maker and narrower production date remain unknown. The owner reads a secondary stamp as '19, GE'; if it is an Italian registration mark, GE would indicate Genoa province. That reading is not sufficiently established to assign Italian origin or a named-workshop premium, and no ownership history is supplied.

Condition & Value
The supplied photographic assessment describes blue enamel, applied twisted-wire strings, and an openwork filigree back without obvious major damage. The owner reports very little enamel wear, intact detailed metalwork, and a clasp that closes firmly.
Full Research
Sold comps, value drivers, and venue guidance pulled from recent auction results.
Silver musical-instrument brooches appeal to vintage-jewelry buyers, musicians, and collectors of figural accessories. eBay and Etsy are practical venues for this modest-value, specialized item. The supplied references suggest a market around the upper double digits for appealing examples, but an asking price does not establish a completed-sale value. Clear enamel, hallmark, and clasp photographs will help distinguish this piece from generic guitar jewelry.
▲ Blue enamel and guitar form give the brooch distinctive wearable and gift appeal.
▲ Openwork filigree and applied wire strings support its decorative-jewelry value.
▲ The visible 900 stamp supports valuation as nominal silver jewelry, pending testing.
▲ Reported secure clasp and limited enamel wear support normal wearable resale pricing.
▼ Silver fineness is untested; a plated or substantially lower-purity result would reduce value.
▼ Small enamel chips or structural repairs, if found on inspection, could reduce buyer appeal.
▼ The ambiguous stated length limits size comparison with the two-inch enamel reference.
▼ The priced references are unverified and include an active asking price, leaving achieved-sale value less certain.
Best Venue
List individually on eBay at approximately $89 with offers enabled; a negotiated sale around $60–$75 would be reasonable, while $45–$55 is a practical faster-sale target. Add sharply focused photographs of both stamps, the enamel edges, strings, and closed clasp, plus an accurate ruler measurement and gram weight. Avoid abrasive polishing or chemical dips, and describe the piece as 'marked 900' rather than guaranteeing tested purity or Italian manufacture.
Upside Potential
Confirmed silver purity, crisp detail photographs, and demonstrably intact enamel could support a sale near $85, consistent with the USD 83. 60 enamel-filigree asking reference and USD 90. 95 displayed sold reference. A legible stamp identifying a collectible maker would justify further research, but the supplied evidence does not establish a premium above this range.
