Each beautiful half moon turquoise stone is set in a lovely sterling silver setting with a 16 gauge wire that partially surrounds the stone. The bands on each ring are half round but each is slightly different. The rings range in size from 7.75, to 8.75 to 10.75. If you are interested in a similar ring, but in a different size, just send me an email - mybrownwren at gmail dot com and I’ll do my best to accommodate you.
