A ring featuring an emerald cut emerald as the center stone, with diamonds arranged around it in a dazzling display. - Main Stone: Emerald - Stone Shape: Emerald Cut - Surrounding Stones: Diamonds - Ring Diameter: 19.1mm - Stone Size: 10.3mm As this is a natural stone, it is not 100% pure. I believe that the high purity of this product, and the difficult cut, is of the highest quality. The engraved markings that were not successful are not clearly visible. The material is also unclear. Please consider this if you are satisfied with the condition. Thank you for viewing.
