Blue topaz comes in both light and dark shades. The light color is known as Sky Blue. The darker tone – London Blue – is sometimes described as being “steely” or “inky”. As with all blue gemstones, the more saturated shades of London Blue tend to be higher priced.
Our gemstone team sources London Blue topaz from high caliber suppliers only. Buying from trusted partners is critically important as the London Blue color is achieved by exposing natural, colorless topaz to heat and radiation. Its spectacularly deep blue color is the result of strict and meticulous treatment processes changing the way the topaz crystals absorb the light.
