Blue Topaz Topaz is the birthstone for the month of December, and the stone given in celebration of the 4th and 19th anniversaries of marriage. Topaz is a symbol of love and affection, and has been said to be an aid to ones sweetness and disposition. According to a well-known industry magazine, Colored Stone, blue topaz has become the 2nd most popular colored gemstone (sapphire is consistently number one). Topaz is a very hard material - 8 on the Mohs hardness scale - and blue topaz is a very pretty stone that is available in a wide range of vivid hues with a striking vitreous luster. 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. Blue topaz is unusual in offering excellent hardness (8 on the Mohs scale) and brilliance. 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.
