Perenially popular, the blue topazes remain unrivalled in terms of their intensity of colour and clarity. Subtle, celestial pale Sky Blue topaz, an ideal choice if you want the look of aquamarine without the price tag; Swiss Blue Topaz, with its vibrant blue colour, the shade of an English summer sky and London Blue Topaz, a deep, sophisticated petrol blue colour, like no other. Topaz is hard, and impervious to most scratching, so it's nice and durable, and has a very high brilliance so there's tons of sparkle. The material I have is super-clean - you won't see any inclusions. Please note; whilst blue topaz does exist in nature it is rare and precious so the majority of blue topaz on the market - including this - is irradiated.
