Solid Sterling Monarch Opal Ring created by Wildflowyr Jewelry This one-of-a-kind ring features a gorgeously colorful blues, yellows and reds Monarch opal. I created the ring from solid sterling silver, using this "floral" patterned silver band, which is 3.4mm wide. I set the 8x10mm opal in a solid sterling crown bezel, which I securely soldered to the band. Pictured in the antiqued version, but you may opt for shiny sterling. I'll set this exact stone in any size that you like. Enlarged pictures to show detail. Ring face is 8x10mm. Gift boxed with bow. A little more about Monarch opal: This cultured opal, as well as natural opal, are both created from particles of silica dioxide and water. However, monarch opal is grown, and it takes 4-6 months for the growing process to complete. This opal color comes from light refraction, NOT dyes. This opal has been classified by the GIA as a true synthetic opal. I offer free resizing on all purchases. If you need a free disposable ring sizer, please ask.
