This antique diamond & ruby rose gold ring dates from the Edwardian period. The three main stones are bezel-set, with the rubies being surrounded by rose gold, & the center diamond being surrounded by possibly silver, just as I believe the top of the ring is. The center, Old European diamond measures 4.0 mm, which equates to .23 carats. The two rubies, although one has a flatter table than the other, are approximately .10 carats each. There are five teeny diamond chips accenting the navette setting. The inside is not marked, but it tests as 14K. Size 6. Condition: Excellent Approximate measurements: 11/16" long (north to south), 1/4" wide Antique Edwardian 14K Rose Gold Diamond & Ruby Navette Ring
