Lab Sapphire Emerald Cut Four-Prong Solitaire Diamond Pavé Shank Ring | S925 Silver Royal Blue Engagement Style

A vivid royal-blue square, held by four silver prongs, above a band where the diamonds run all the way to the sides. The ring that makes the step-cut format feel like it was invented for this exact shade of blue.

A large, near-square emerald-cut lab-grown sapphire in vivid, deeply saturated royal blue sits in a four-prong solitaire setting — one rounded prong at each corner — above a round brilliant white diamond pavé shank: approximately eight to ten small round brilliant white diamonds, continuously set along each side of the band from the stone setting outward to the shank’s mid-section, create a considered border of white diamond brilliance running the length of the visible shank on both sides. The pavé shank’s considered construction — the continuous white diamond rows running parallel to the band’s length on each side — creates a shank of exceptional white diamond richness and considered visual weight, the white diamond rows’ linear, directional character drawing the eye inward toward the sapphire from both sides simultaneously. The emerald cut’s distinctive step-faceted table — its large, open rectangular crown facet and parallel step facets creating a stone of exceptional considered depth and architectural clarity — creates a centre stone of exceptional commanding presence and considered geometric authority above the pavé shank’s surrounding white diamond brilliance. The near-square emerald cut’s large, open table facet maximises the sapphire’s vivid royal blue colour saturation, the deep blue’s considered depth creating a stone of exceptional colour authority and considered architectural presence.

Why You'll Love It

• Emerald cut — architectural depth and step-facet clarity — the emerald cut’s large, open step-faceted table and parallel step facets create a stone of exceptional considered depth and architectural clarity; the near-square form’s large open table facet maximises the sapphire’s vivid royal blue colour saturation, and the step facets’ considered directional light creates a stone of exceptional colour authority and geometric presence
• Diamond pavé shank — white diamonds run to the sides — approximately eight to ten round brilliant white diamonds continuously set along each side of the band create a considered border of white diamond brilliance running the length of the visible shank; the pavé shank’s white diamond rows draw the eye inward toward the sapphire from both sides simultaneously, and the continuous pavé gives the ring a sense of exceptional considered diamond richness beyond the centre stone alone
• Four-prong corner setting — the square is uninterrupted — one rounded prong at each of the emerald cut’s four corners reduces the silver’s presence to its absolute minimum while maintaining the stone’s security; the corner-prong construction allows the emerald cut’s full rectangular outline to be visible and uninterrupted from above, and the minimal prong presence allows the sapphire’s vivid royal blue to dominate the ring head
• Available in AU sizes H–T — twelve AU ring sizes available, from H to T, ensuring a precise and comfortable fit; please refer to our Ring Size Guide to find your size before ordering
• Guilt-free luxury — lab-grown sapphires share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
