THIS STONE IS A STRONG STEEL BLUE, ALL NATURAL, MONTANA SAPPHIRE. THERE IS A LITTLE HALO OF SILK IN THE CENTER OF IT THAT COULD'VE (COULD STILL) BE HEATED OUT OF IT. HOWEVER, THE TONE OF COLOR IN THIS GEMSTONE IS SO BEAUTIFUL AND WELL APPRECIATED. TO RISK HEATING IT, IS TOO GREAT, AS IT IS SO HARD TO SEE WITHOUT A LUPE OR MICROSCOPE. THIS WOULD MAKE A VERY BEAUTIFUL NECKLACE.
