Swiss, London or sky blue?

Sky blue is the lightest and softest. Swiss blue is a bright, saturated medium blue, the most popular for everyday jewelry. London blue is the deepest, with a slightly inky tone.

All three are natural topaz whose colour is produced by treatment, which is stable and permanent in normal wear.
