Raw Faceted Aquamarine Silver Necklace - Simple and understated! Four claw prongs grasp the icy raw aquamarine and above it is a glistening faceted oval matching stone. Celebrate a March birthday in the most unique way or let cool sky blue tones take you away. Due to the nature of raw gemstones, each piece is often built around the stone's natural contour making them all nearly one of a kind.
