Montana Sapphire Shades of Blue Round 0.85 Carat MTY00274

As seen in the video, this is a clean, bright gemstone. The cutter faceted this stone in a Portuguese pattern instead of the traditional round brilliant to bring out the sparkle in this sapphire. This gemstone displays a weak color change depending on the light source, generally in the range of medium to dark blue, including steel blue and dark Navy blue. Most of the images were taken in normal lighting, but we included one picture taken in 4200K fluorescent lights to highlight the color change. This gemstone can be set in either a ring or pendant.
