This ring is actually three rings - a 3-stone ring with bands above and below. They appear to have become joined together when they were sized . I am quite certain the center stone is synthetic, as it is very sparkly and incredibly clear. The diamonds have been tested and are genuine. They are very white and clean and estimated, based on their measurement, to be 20-25 points each. The top and bottom bands are marked 14k, and the prongs on the center ring test 14k as well. (Due to the fact that the three rings are joined together, it was difficult to test other parts of the center ring separately). Shipping is free to US residents.
