There are 3 pieces of lab created opal inlaid on each side of the ring. The four princess cut blue topaz total .60 carats and are channel set down the center of the ring. The ring is 15 mm wide at the top and tapers down to about 6 mm at the bottom. It is available in sizes 8 to 11 by special order in 3 to 6 weeks. Sizes larger than 11 will be a small additional charge. Other inlay stones and colors are also available. The lab created opal in this ring is a top quality synthetic opal grown under laboratory conditions. The manmade opal's chemical composition is the same as natural opal with the exception of water content. Australian opal contains about 4% water and lab created opal contains no water. Instead the water is replaced with resin. The resin gives the synthetic opal more durability and helps to resist cracking. Laboratory grown opal gives you all the fire and colors of top grade natural opal at a much more affordable price with increased durability. Ring style #MD252
