Lab Sapphire Oval Three-Row Pavé Dome Band Ring | S925 Silver Full Diamond Bombé

Royal blue at the top, diamonds all the way down. The ring that looks like it was carved from a single block of light.

A large oval-cut lab-grown sapphire in vivid, deeply saturated royal blue sits in a four-prong setting at the crown of a three-row round brilliant diamond pavé dome band — round brilliant diamonds cover the entire surface of the band in three parallel rows, running from the base of the sapphire setting down both shoulders and continuing around the full circumference of the ring in a continuous, unbroken field of brilliance. The band’s bombé profile — a gently domed, convex cross-section — gives the ring a sculptural, three-dimensional quality that a flat band cannot achieve; the dome catches light from above and from the sides simultaneously, creating a ring that appears to glow from within. The oval sapphire’s elongated silhouette maximises the stone’s vivid royal blue colour and creates a commanding focal point above the diamond dome. Available in AU sizes H–T. At $211.50, this is the sapphire ring that earns its place as the most considered piece in any collection.

Why You'll Love It

• Full bombé diamond dome band — three rows of round brilliant diamonds cover the entire surface of the domed band, creating a ring with a continuous, unbroken field of brilliance from crown to shoulder; the bombé profile’s convex cross-section catches light from multiple angles simultaneously and gives the ring a sculptural, three-dimensional presence that a flat pavé band cannot replicate
• Oval sapphire centrepiece — the oval cut’s elongated silhouette maximises the sapphire’s vivid royal blue colour saturation and creates a commanding focal point above the diamond dome; the oval’s soft curves sit naturally within the dome’s rounded profile, creating a composition of exceptional visual harmony
• Three-row pavé construction — three parallel rows of round brilliant diamonds running the full length of each shoulder create a band with far more diamond coverage and brilliance than a single-row pavé; the three-row construction gives the ring a substantial, fine jewellery weight and presence on the finger
• AU H–T sizing — available in a full range of Australian ring sizes from H to T; please refer to our Ring Size Guide to find your perfect fit before ordering
• Guilt-free luxury — lab-grown sapphires share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
