Soft blue semi-transparent aquamarine oval 10x14mm stone earrings. Sometimes the camera cannot capture the true beauty of what our eye can see but if seen in person these aquamarines are gorgeous. When the light hits them they give off a light blue glow. Aquamarine is a precious stone, not semi-precious, a type of beryl in the emerald family. A perfectly clear aquamarine of this size would cost a great deal (thousands) and be set in gold. The type of aquamarine set in silver is more of a cloudy blue. Aquamarine is March's birthstone.
