Mom loves Opal earings. There were one of her mother's day gifts and her favorite of all. 6mm by 11mm, bright opal with clean shine and sparkle, obviously real and very nice workmanship on sterling sivler, nice and long hook... I got great quality for the money. No allergic reaction. These will go with ANYTHING that you have in your closet and will go for any occation short of little exaggeration. I think any woman can use these to make them look better and feel better.
