Antique circa 1910’s to 1920’s rare Ostby & Barton Sterling Silver, 10k Gold and Banded Agate ring . This ring has a Titanic connection, details further down.
The pattern on the stone is truly amazing, thanks to Nature and to the expertise of the Lapidary to foresee this striking end result. The setting is lovely too, adorned with a quatrefoil flower at each side. These flowers are 10k Yellow Gold and appear to be applied to the Sterling Silver shank.
Ring setting measures almost 1/2″ tall by 11/16″ flower to flower and the stone rises a maximum of 3/16″ above the hand. Size is petite, US size 5 or about 15.75mm in diameter. There are no chips on the stone but there is a small circular inclusion on the lower left of the scene. It is a natural occurrence and not damage.
Ring is marked OB initials and Sterling + 10k. Carefully tested to verify content. It has been hand polished, some patina is present.
Engelhart Cornelius Ostby was born in Oslo, Norway and immigrated to the United States in the late 1800’s. In partnership with Nathan B. Barton founded the Ostby Barton company in 1879 located in Providence, Rhode Island. The business prospered greatly and in the early 1900s was the largest manufacturer of gold rings in the US. Starting in 1906 Mr. Ostby traveled with his daughter every year to Europe to see new styles and purchase gemstones for his jewelry. In 1912 they returned on the Titanic. Mr. Ostby perished on that fateful voyage but was survived by his daughter, Helen.
Ostby Barton jewelry is beautifully made and the Agate rings they produced are without equal. This is one of the finest examples I have seen.
