3" This appears to be a vintage gold-tone stick pin featuring an oval, textured head accented with a central clear rhinestone and two green side stones.

The back of the stick pin reveals a textured, cross-hatched metal backing and shows how the straight pin stem is securely soldered or attached to the decorative head.

Since there are no hallmark markings, maker's stamps, or precious metal indications (such as 14K or Sterling) anywhere on the back or stem, this item is classified as vintage costume jewelry. 

Unmarked gold-tone vintage costume stick pins from the mid-to-late 20th century generally have a modest market value.

Estimated Value Range

• $8.00 to $18.00 USD 

Key Value Factors

• Materials: It is constructed from a non-precious gold-plated or gold-tone base metal. The accents are costume-grade rhinestones or glass stones rather than precious gems.

• Condition: The overall resale value depends heavily on the preservation of the gold finish on both sides and whether the stones retain their original clarity and sparkle. 

• Market Context: While there is a dedicated base of vintage fashion collectors, high-volume production of unmarked pieces during their peak eras keeps individual pricing relatively low
