Premium Aquamarine Rare large beads! ☆ These large sizes are hard to find on the market! ☆ This aquamarine bracelet is highly transparent, beautifully colored, and is a member of the beryl group. ☆ Aquamarine is named after the Latin word for seawater. As the name suggests, it is characterized by a beautiful blue color like the sea, but the aquamarine that has arrived this time is highly transparent with a strong blue hue, making it a rare large bead aquamarine♪ Most aquamarines undergo heat treatment to remove green tones, so aquamarine is almost always heat-treated at a low temperature of 400 degrees. Currently, it is impossible to determine whether this heating has been done or not with current technology, and it is impossible to distinguish between heated and unheated, as with citrine, so aquamarine is considered to include heat treatment like citrine. The cause of the color is mainly due to iron, and heat treatment is performed to enhance the color of the gemstone, but how beautiful it becomes through this heating is an important point when choosing aquamarine ☆ This is a beautiful aquamarine that meets certain conditions from the perspective of color and transparency ☆ ※Photographed with LED (white) light.
