Simply beautiful and so elegant! This is a wonderful example of the fine jewelry produced in the Edwardian era. A delightful pierced filigree setting houses a fantastic chalcedony cabochon stone. Great hues and transparency that are very eye catching. The center is adorned with an old European cut diamond that is approximately 6mm wide. Very good cut with lots of fire and brilliance! I believe this to be 1/2 carat in size. The chalcedony measures 5/8 of an inch long by a bit under 1/2 an inch wide. Rings size is 7 1/4. In well cared for condition this beauty is ready to wear and enjoy for years to come. The shoulders have a very faint curve to them as seen in the photo. Upon close inspection it appears to have been made this way. Does not deter from the ring and noted for accuracy. A fantastic addition to add to your collection. This is so beautiful in person and will be noticed by all! Please ask questions prior to placing an order! Thanks!
