Blue gemstones with good hardness and brilliance tend to be rare and fairly expensive. This is especially true of the darker blue gems, such as sapphire, tanzanite and spinel. There are other, less expensive gems in a saturated deep blue, including kyanite, lapis lazuli, iolite and fluorite. But these are much softer stones that are not suitable for everyday jewelry such as rings.
It is not surprising then that blue topaz has become one of the top selling gems in the jewelry business. Blue topaz is unusual in offering excellent hardness (8 on the Mohs scale) and brilliance at a very reasonable cost.
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.
London blue topaz is a medium to dark grayish blue, sometimes described as "steely" or "inky". Many London blue gems have a slightly greenish tone when viewed from certain angles.
