A Striking Emerald and Pear Cut Moissanite Engagement Ring
The Comet is a wonderfully gorgeous engagement ring that will steal your breath away. A mesmerising emerald cut moissanite and a delicately rounded pear cut moissanite sit side by side at the heart of the ring, set in 18k yellow gold. The two stone toi et moi design captures the union of two lives in one striking, contemporary engagement ring.
The Comet is one of our most distinctive yellow gold toi et moi engagement rings, designed for those who want something truly unique on the finger.
Lily Arkwright Moissanite Centre Stones
Every Lily Arkwright moissanite stone is ethically sourced and carefully selected. Each moissanite stone is inspected and graded by a fully qualified gemologist before being set into a piece. All moissanite stones in the Comet are accompanied by a certificate of authenticity and a limited lifetime warranty.
The Two Stone Toi Et Moi Setting
A toi et moi design pairs two stones at the centre of the ring, symbolising the meeting of two lives. The Comet brings together an emerald cut and a pear cut moissanite, two contrasting silhouettes that complement each other perfectly. The emerald cut adds clean lines and architectural elegance, while the pear cut softens the design with a rounded, romantic curve.
The 1.65mm band width keeps the Comet feeling delicate, letting the two stones dominate the design as they should.
Stone Size and Metal Options
The Comet is offered with centre stones from 5x3mm up to 12x8mm. Additional sizes are available upon request, so the proportions of the ring can be tailored to the wearer.
The Comet is set in 18k yellow gold.
This piece has been certified in accordance with the Hallmarking Act 1973.
