These simple earrings almost gave one of my staff heart palpitations. She fell in love with the look of them. I thought they were a simple earring that was subdued but I found out I was wrong according to my staff. The gemstones are druzy agate with a titanium plating over the druzy to create quite a sparkle on the natural gemstone. Hung from a lever back, they have some movement. With the titanium plating, they sparkle like diamonds.
