Value Factors

• Materials: Based on its visual appearance, this is costume fashion jewelry featuring a gold-tone base metal and either glass, resin, or faux/low-grade nephrite jade. If the metal tests positive for a solid precious metal like 14K gold, the value would jump significantly to $150 to $300+ based purely on gold weight and fine jewelry collector demand. 

• Completeness: Having the 3" length completely intact alongside its original protective end cap (clutch) keeps it on the higher end of standard costume jewelry pricing, as these functional pieces are frequently lost over time
