Lab Sapphire Pear Cut Half-Moon Diamond Halo Ring | S925 Silver Marquise Vine Band Engagement

A deep blue teardrop, a crescent of diamonds below it, and a vine of diamonds along the band. The ring that has always meant something.

An oversized pear-cut lab-grown sapphire in vivid, deeply saturated royal blue sits in a three-prong setting — one prong at the pointed tip, two at the rounded base — above a half-moon round brilliant diamond pavé halo that traces the curved lower arc of the pear, leaving the pointed tip open to create a crescent silhouette of diamond brilliance beneath the stone. The band is a marquise leaf and round diamond vine — alternating marquise-cut and round brilliant diamonds set along both shoulders in a continuous vine or leaf pattern that tapers gracefully toward the back of the ring. The combination of the pear sapphire’s dramatic teardrop silhouette, the crescent diamond halo’s romantic arc, and the vine band’s organic movement creates a ring of exceptional narrative depth — a composition that has been associated with the most significant sapphire engagement rings in history. At $202.50, this is the sapphire ring that earns its place as the most meaningful piece in any collection.

Why You'll Love It

• Half-moon diamond halo — round brilliant diamonds trace only the curved lower arc of the pear sapphire, creating a crescent or half-moon halo that frames the stone from below without enclosing it; the open upper silhouette of the pear’s pointed tip creates a dramatic, asymmetric composition that a full halo cannot achieve
• Marquise vine band — alternating marquise-cut and round brilliant diamonds set in a vine or leaf pattern along both shoulders create a band with organic movement and botanical character; the marquise cut’s elongated, pointed silhouette creates leaf-like forms that give the band a romantic, garden-inspired quality
• Pear-cut sapphire centrepiece — the pear cut’s teardrop silhouette is among the most romantic and distinctive in fine jewellery; the elongated form maximises the sapphire’s vivid royal blue colour and creates a focal point of exceptional presence on the finger; the pear’s pointed tip draws the eye upward and gives the ring a sense of direction and intention
• Engagement and proposal ready — the pear sapphire halo ring is one of the most celebrated engagement ring formats in fine jewellery history, associated with significant milestones and worn as a symbol of enduring commitment; the combination of the sapphire’s vivid blue and the diamond halo’s brilliance creates a ring that photographs beautifully from every angle
• Guilt-free luxury — lab-grown sapphires share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
