How to Identify Signed Pieces
Signatures and maker's marks are typically found in specific locations:
Brooches
Back of pin, often on clasp or flat area
Necklaces
Clasp or hang tag
Earrings
Back of clip or post
Bracelets
Clasp or inside of bangle
Pro Tip: Use a magnifying glass — many marks are small and can be easily missed.
What Affects Value?
Condition
No missing stones, intact plating, working clasps
Rarity
Unusual designs or limited productions
Size
Statement pieces often more valuable
Completeness
Full sets (parures) worth more than singles
Frequently Asked Questions
Possibly! Signed pieces from quality makers can be worth $50 to $2,000+. Even unsigned pieces may have value if they're from identifiable designers. Bring them in for free evaluation.
Not always. Some valuable pieces were never signed (like Juliana). We can often identify makers by style, construction, and materials.
Missing stones are the biggest issue. Worn plating reduces value but less dramatically. Broken clasps are usually fixable.
