Lab Ruby Round Marquise Sunburst Halo Ring | S925 Silver Adjustable Diana-Style

A vivid ruby at the centre of a diamond sunburst. The ring that has always belonged on a very important finger.

A large round brilliant-cut lab-grown ruby in vivid rose-red sits within a marquise and round diamond alternating sunburst halo — eight marquise-cut diamonds with their pointed tips facing outward, alternating with round brilliant diamonds between each point, creating a full, radiating star silhouette of exceptional brilliance. The design shares its DNA with the most celebrated ruby and sapphire rings in jewellery history: a bold coloured stone at the centre of a diamond crown, worn with complete confidence. The open adjustable band fits any finger. At $189, this is the statement ring that earns its place in any collection.

Why You'll Love It

• Marquise sunburst halo — eight marquise-cut diamonds with pointed tips facing outward, alternating with round brilliant diamonds, create a full radiating star silhouette around the ruby; the marquise sunburst halo has far more visual drama and movement than a standard round brilliant halo, and the alternating pattern gives the ring a couture quality that is immediately distinctive
• Round brilliant ruby centrepiece — the round brilliant cut maximises the ruby’s vivid rose-red colour and creates a bold, symmetrical focal point within the sunburst halo; the colour is known for its skin-brightening colour effect and sits beautifully within the all-white diamond surround
• Diana-style design language — a large coloured gemstone at the centre of a diamond halo on a plain band is the most celebrated ring format in fine jewellery history; this interpretation with its marquise sunburst halo adds a contemporary, architectural dimension to a timeless composition
• Adjustable open band — fits any finger without sizing; ideal for gifting or for those who prefer flexibility; the open band can be gently adjusted for a comfortable, secure fit
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
