Antheia Trilogy Ring
Antheia was the goddess of flowers, spring, gardens and blossoms who embodied beauty, charm, and joy.
Honouring her timeless allure, our new Antheia Trilogy Ring forms part of our New Engagement Ring Collection, capturing the essence of graceful elegance with a fresh, contemporary spirit.
This refined trilogy design features a breathtaking 3.0ct oval-cut lab-grown diamond at its centre, flanked by two elegant trilliant-cut shoulder stones that reflect light from every angle. Crafted in Platinum, Antheia blends symbolic storytelling with modern design — a standout choice for those seeking a meaningful and sophisticated engagement ring.
