Certified Moissanite Collection

Why Moissanite?

Moissanite is redefining what modern fine jewellery looks like.

As the UK market moves towards more conscious and intelligent luxury, moissanite has emerged as a compelling alternative to traditional mined diamonds — offering exceptional brilliance, ethical sourcing and visual impact without compromise.

Celebrated for its superior fire and light performance, moissanite reflects more brilliance than conventional gemstones, delivering a presence that is both refined and unmistakable.

Each Rubielle moissanite piece is independently certified by the GRA (Gemological Research Association) and accompanied by its individual certification report — providing documented grading and authenticity for complete assurance.

Set in 925 sterling silver and finished in white rhodium or 18k gold plating, our designs embody contemporary craftsmanship with enduring sophistication.
