About the stone

London Blue topaz carries the most intense and deepest blue in the topaz family — an inky, slightly grayish, sophisticated blue.

It’s fair to say: this shade doesn’t occur in nature.

It’s created from colorless topaz, irradiated to deepen its color.

Just like Sky Blue, it’s a safe, industry-standard process, and quality stones are tested before sale.

The name “London Blue” has become synonymous with a rich, elegant blue, highly sought after in modern jewelry.

Unlike the lighter Sky Blue tone, the London variety has a distinct depth that gives it a contemporary edge.

The color is a deep, intense blue with subtle greenish undertones.

The underlying topaz comes primarily from Brazil and Nigeria.

Associated with clarity, confidence, and balance, its deep tone makes it a go-to choice for statement pieces.

With a hardness of 8, it’s durable, needing only protection from strong impacts and sudden temperature changes.

It should be cleaned gently and looks beautiful in 925 silver and white gold.

Attention level
Cleaning
  • Warm water with soap or a gentle professional jewelry solution.
  • Avoid ultrasonic cleaners if the stone is not clearly compatible (e.g., some amethysts or topazes may be affected).
  • Avoid steam cleaning unless specifically safe for that stone.
Exposure precautions
  • Remove jewelry before intense physical activities or entering chlorinated pools.
  • Avoid contact with strong chemicals (chlorine, ammonia).
  • Some stones may lose color with prolonged sun exposure; store them properly.
Storage
  • Store in soft pouches or separate compartments to prevent scratches.
  • If the metal oxidizes easily (like some silver alloys), consider anti-tarnish strips.
  • Avoid areas with high humidity (bathrooms, saunas).
