Antique Opal Gold Ring by Ostby Barton Square Shape October Birthstone, 10k Yellow Gold, Marked OB 10k & tested Highly collectible as one of the jewelers, Ostby, perished on Titanic in 1912 See pics for confirmation of condition. This is a antique ring & wear is to be expected. Size 6, weighs 1.7g, setting measures 11mm x 9mm I have been an avid collector of vintage/antique jewelry. Ostby pieces are one of my favorites & this is from my personal collection. (The last pic shows more of my personal collection) I keep my jewelry as found, but if one so desires, stone could use a professional polish. All proceeds fund our equine/canine animal sanctuary.
