I marked a spot on a pic where there is the teeniest blemish on the nacre. The bottoms show a bluish green coming through. It’s not on the surface that I can tell. It’s not seen when they are worn unless you look up underneath them. Please check the photos carefully as I pictured what I see so you can determine for yourself. Overall, they are still in good condition and have plenty of life left in them. The pearl color is not a true white. They almost have a blush pink undertone in some lighting
