At 6.81 carats, this piece is sizable enough to display its color play beautifully. Certified by the International Colored Gemstone Association (ICA GemLab), the stone's qualities and authenticity have been verified professionally. Green and yellow tourmalines are popular for their bright, sunny appearance and are frequently used in elegant jewelry designs due to their hardness and vibrant palette.
