What Is London Blue Topaz
A cool, grey-tinged deep blue
London Blue Topaz stands out among blue topaz for its deep, calm blue with a hint of grey. Understated yet refined, it suits everyday wear through to formal occasions. Topaz rates 8 on the Mohs scale, and it is the November birthstone.

The clear, deep blue softens under light, shifting from deep navy to bright blue depending on the angle — a rich range of blue in a single stone.
About the Color, Honestly
Where does this blue come from?
Naturally blue topaz is extremely rare. Because of this, most blue topaz on the market is created by treating colorless topaz with irradiation. The resulting color is very stable and does not easily fade.

We believe in sharing this honestly — the treatment and the background of every stone. Knowing a stone's story, we hope, lets you wear it with confidence for years to come.
Meaning & Symbolism
A stone of friendship and hope
Topaz's stone meanings are "friendship" and "hope." Its clear blue is said to symbolize hope and positive change — a calm, deep blue for those who wish to stand quietly as themselves.
Birthstone
Topaz is the November birthstone. Its deep, clear blue makes a fitting gift for those born in November.
