London Blue Topaz

Blue topaz is traded under specific color varietal trade names such as Sky-blue, Swiss blue and London-blue. London blue is the deepest of blue topaz colors and is described as being a medium to dark grayish-blue, sometimes referred to as 'inky' blue.

London blue topaz gems will often have a slight secondary greenish tone when viewed from certain angles. Of all the many different colors of blue topaz, London blue is the most prized and usually the most valuable.

London blue topaz is considered 'natural topaz' although it has been treated (the colors of London blue are formed through an artificial irradiation enhancement process), and it remains as one of the more affordable gemstones on the market, even in larger sizes; especially when compared to the prices of other popular blue gemstones, such as aquamarine, blue zircon and most especially, blue sapphire.

I like to use GemSelect for finding calibrated sizes of gemstones. I purchased sapphires a few years ago and found the quality to be outstanding so I went ahead and purchased some more today (different) and some really unique moonstone. I'm opening a jewelry busy soon and so accurate gemstone sizes, quality, and reliability as a supplier is really important to me. Gemselect seems to fill all those requirements.
