Thank you for reaching out Yvonne, I am so glad you found us!
Your 10k Banjo Pendant marked with an OB stamp is made from solid 10-karat gold in the shape of a miniature musical instrument charm. The Pendant was made by the notable vintage jewelry maker Ostby & Barton Co. (often stamped as OB 10K or O-B 10K).
The "OB" mark stands for Ostby & Barton, a prominent American jewelry manufacturing company based in Providence, Rhode Island, operating in the 19th century throughout the mid-20th century.
Particularly noteworthy is the fact, that the founder, Englehart Ostby, was a passenger on the RMS Titanic and tragically passed at the crack of doom at the evil hour when the Titanic sunk. This historical, tragic significance makes Ostby & Barton pieces highly sought after by collectors of vintage Jewelry and Titanic-era memorabilia.
