Similar to a navette style, this ring has three stones that are set north to south. The measurement in that area is 14 mm. The total weight is 1.9 g and the current size is a 5.5. Any reputable jeweler could easily size this piece. The center stone is green and is prong set. It measures approximately 5 mm wide. It is flanked by two prong set diamonds. The scrolling details on the side are lovely and feminine. The interior of the ring is signed with the letter A and a five pointed star. The band in the back is not thinning and overall is in excellent condition. Please be sure to check out my other antique Victorian rings for sale. I add new items frequently.
