Overview:
Finely detailed Art Deco era ring (circa 1920s to 1930s), crafted in 14 karat white 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.
Onyx and rock crystal are inlaid into the mount measuring 15mm x 7mm, accented with an estimated 0.01 carat single cut diamond (estimated at J color and VS2 clarity). Note: few chips to the inlaid mount (visible under a 10x loupe).
