Ethiopian Welo Opal Ring on Decorative Band Size 6.25 USThis sweet Welo opal just glows with so many flashing colors, but is so hard to capture in a photo! The thick rectangle sterling silver wire has a sunflower pattern and was formed into a size 6. 25 US. Avoid submerging this stone in liquids whether it's water, oils or lotions. Please remove opal jewelry before washing hands, putting on lotion, swimming, showering or similar activities. I say this for all my jewelry because really, it's the best thing
