Boutique Exclusive

Our Rainbow Sapphires are exclusive to Alex's London Bridge Boutique.

The one location to view our entire Fine Jewellery range first hand and receive expert advice from our dedicated team.

How it works

Start by choosing either a 2.5mm or 3.3mm ring style.

Choose your metal colour - 18ct yellow, white or rose gold.

Then pick your favourite Rainbow Sapphire stone and we'll do the rest!

Our Sapphire Selection

Our Rainbow Sapphires are ethically sourced from the Island of Madagascar and are completely natural.  Unlike conventional gemstones, they have not been heat treated to intensify their colour and uniformity.

As a result they possess a freshness, lustre and complexity of colour impossible to find in any other stone.  Only one in every one hundred Sapphires to come out of the ground remains untreated, and so can be considered truly natural.

Naturally stunning and impossible to replicate, a Madagascan Rainbow Sapphire is rarer than a diamond…and a unique representation of the Earth’s untouched beauty.
