About Moissanite

Moissanite is not an alternative to luxury.
It is a modern evolution of it.

Celebrated for its extraordinary brilliance, fire and durability, moissanite has become one of the most remarkable stones in contemporary fine jewellery — combining exceptional optical performance with a distinctly modern perspective on luxury and value.

Originally discovered within a meteor crater, moissanite is renowned for its intense light refraction and unmistakable fire, often displaying even greater brilliance than traditional diamonds. With a hardness of approximately 9.25 on the Mohs scale, it is highly resistant to scratches and designed for lasting everyday wear.

At Rubielle London, every moissanite stone is carefully selected for its clarity, proportion and light performance. Precision-cut to maximise brilliance from every angle, our moissanite pieces are created to embody presence, refinement and enduring elegance.

We believe luxury should never depend solely on tradition or inflated perception.
It should be defined by beauty, craftsmanship, transparency and intention.

This philosophy is reflected in Rubielle’s approach to moissanite today: intelligent luxury without compromise.

All certified moissanite pieces are accompanied by dual certification:
• An individual GRA certificate issued by the Gemological Research Association
• Rubielle London’s own Moissanite Certificate

Designed for lasting presence.
