This is a big one! Very large and chunky! I used a gorgeous piece of Turquoise (almost 2" x 1 1/8" at widest) in this adjustable ring. This Turquoise has shades of light aqua blue color in a dramatic black matrix....so intriguing! Bezel set in fine silver .999 to a hammered sterling silver band. Band is 15mm wide and size is 9, but can go up 1-2 sizes. With a wider band like this figure at least 1 size up than you would wear with a thinner band. To go down in size just let me know. Thanks!
