This ring is a replica of Princess Diana/Kate Middleton's ring. The Oval (not round) center stone is a rich deep blue sapphire color, with Oval cuts for gorgeous sparkle.  The center stone is approximately 5cts and is surrounded by small clear crystal stones that hug the large center stone.  Center stone is PAVA set and the clear outside stones are prong set.. The 14k white gold over sterling silver is very rich looking and long lasting. In addition to selling over 100 of these rings, with no complaints. Most of the rings I have for sale now come with a beautiful ring box, making it easy for gift giving or to store your lovely ring.  I have one for personal use and have worn it a lot over the past 14 years and there is no tarnish on the band the stones look like the day I put it in my jewelry box.  The ring is outstanding and I believe it will look that way 20 years from now with normal wear.
