Extra large pieces of natural Aquamarine exhibit the beautiful milky Blue color tones & internal sparkle so sought after in this gemstone. Beads are shaped like an oval to an elongated diamond and are diagonally faceted across the larger faces (similar to a spiral facet but a bit smoother between facets). They show none of typical brown to yellowish inclusions that we usually see in Aquamarine that is this large. Due to the very large size, you will see some slight surface voids or roughness where the natural contours of the gemstone was not completely polished away. Beads vary in length from 20 to 35mm, from 12-18 wide and 7-14mm thick. Drilled on the long dimension as shown by the pin in the picture; hole openings can be slightly enlarged. Sold individually.
