This is a natural untreated pale blue 6.69 Ct oval brilliant cut aquamarine gemstone. This aquamarine would look nice set in a ring.When taking video of this certified beauty, it appeared to reflect red light…if I positioned it a certain way. I like the photo where you can see a prism of light hit the gemstone. Aquamarine is a pale-blue to light-green variety of beryl. Aquamarine is derived from two Latin words: "Aqua" meaning "water" and "marina" meaning water.
