Swiss Blue and London Blue
Two varieties of treated blue topaz have become dominant. These are known as “Swiss Blue” and “London Blue” topaz. Swiss Blue is a bright blue topaz with a light tone and light to moderate saturation. London Blue is a dark blue topaz with a moderate to dark tone and saturation.
These two colors give jewelry buyers a choice of two blue colors. London Blue is the current market favorite. It is only slightly more expensive than Swiss Blue topaz.
