3.25ct EMERALD CUT NATURAL LONDON BLUE TOPAZ. London Blue Topaz is a medium to dark grayish blue, sometimes described as "steely" or "inky." Many London Blues have a slightly greenish tone when viewed from certain angles. Natural topaz occurs mainly in white (colorless) and brown; natural blue topaz is actually very rare. Blue topaz can be found in both lighter and darker tones, usually known in the trade as Sky Blue Topaz, Swiss Blue Topaz and London Blue Topaz. As in the case of other blue gems, the more saturated blues tend to have a higher value. So in topaz it is the London Blue that usually regarded as the most valuable. RP34
