Vintage Art Deco Ring Ostby Barton Square Signet Initials Sz 11 Men's Jewelry



Finely detailed Art Deco era ring (circa 1934), crafted in 10 karat rose gold.

The ring is made by Ostby & Barton, one of the most well known jewelry manufacturers of the period. The firm was founded in 1879 and ceased production around the 1950s. Sadly, Ostby perished aboard the Titanic whilst his elder daughter survived. Today, Ostby & Barton jewelry is highly desired by collectors of fine vintage jewelry for the exquisite workmanship and history behind the company.

The square signet is engraved with the initials "MG", framed with black onyx. The inner band is engraved "Josephine to Martin 12-4-1935". The ring has a low profile (4mm - 0.15 inches) and sits comfortably on the finger. The ring is in good condition with patina evident. We have not cleaned the ring in order to preserve the patina and collector value.
