As can be seen in the video and pictures, this gemstone is the shade of blue that sapphires from Montana is famous for. The original crystal structure in this sapphire is visible under high magnification, but is not visible under the naked eye due to the stone’s high level of scintillation. The scintillation is so bright that this sapphire is quite noticeable from several feet away. It is suitable for either a ring or pendant, and the scintillation is high enough for it to be set in a small engagement ring. https://youtu.be/GGLouAHiD_A GEMSTONE: Sapphire ORIGIN: Montana WEIGHT: 0.68 Carat COLOR: Light to Medium Blue CUT: Round SIZE Approx. 5.10 x 3.49mm QUALITY: Visible Crystal Structure Under Magnification TREATMENT: Heat
