This Beautiful 4mm Round Brilliant Cut Genuine Aquamarine looks like a drop of water. It's Watery Blue Color reminds me of a great old saying "That's Water Under the Bridge" which is used to refer to events or situations that are in the past and consequently no longer to be regarded as important or as a source of concern. Set in 14Kt Yellow Gold, this pendant dangles from an 18" 14Kt Yellow gold box chain.
