Cassia is a luminous dance between light, warmth, and form — a ring where geometry and emotion meet. Three uniquely shaped gemstones, each with their own character, are composed in harmony to evoke balance and individuality. The design flows with quiet confidence, revealing new details from every angle.

At its centre rests a striking lab-grown kite-cut diamond, its brilliance crisp and architectural, symbolising modern love and clarity of purpose. On one side glows a marquise-octagon Australian sapphire, untreated and naturally radiant, shifting in tone with the light — a reflection of Australia’s wild landscapes and the authenticity of nature. Completing the trio is a pear-cut Argyle champagne diamond, warm and delicate, its golden hue a subtle nod to one of the world’s most storied diamond origins.

Set in 18-carat yellow gold, Cassia’s form celebrates asymmetry and connection — a contemporary take on the classic trilogy that speaks to creativity, individuality, and enduring devotion.

The Significance of Trilogy Rings

Trilogy rings carry a timeless symbolism — the three stones representing the past, present, and future of a relationship. The centre stone shines for the brilliance of the present, while the side stones honour cherished memories and the promise of what is yet to come. For many, the trio also embodies friendship, love, and fidelity — the foundation of lasting connection. Cassia embraces these meanings with elegance, transforming a modern composition into a story of harmony, heritage, and heart.
