Lab Sapphire Emerald Cut Centre Full Diamond Tennis Necklace | S925 Silver Four-Prong Royal Blue Statement

A vivid blue rectangle at the centre of a chain that is entirely made of white diamonds. The necklace that makes the word “statement” feel like an understatement.

An oversized emerald-cut lab-grown sapphire in vivid, deeply saturated royal blue — set horizontally with its wider dimension running across the neckline — sits in a four-prong setting at the precise centre of a full-length round brilliant diamond four-prong tennis chain of exceptional considered construction: approximately eighty to one hundred round brilliant white diamonds, each individually set in a four-prong silver mount, arranged in a continuous, unbroken sequence along the full length of the chain from clasp to clasp, with no plain silver links visible between the diamonds. The tennis chain’s four-prong construction — each diamond held by four individual prongs rather than a bezel or channel — allows each stone’s full round brilliant fire to be visible from above and from the sides simultaneously, creating a chain of exceptional three-dimensional white diamond brilliance that catches light from every angle as it moves. The emerald-cut sapphire’s large rectangular table facet — its vivid royal blue occupying a substantially larger footprint than any individual chain diamond — creates a centre stone of exceptional commanding presence within the continuous white diamond chain, the deep blue’s colour saturation and the emerald cut’s clean architectural step-facets creating a considered contrast with the chain’s organic round brilliant fire. The sapphire is set directly into the chain at its centre point, with no separate bail or pendant mount, giving the necklace a considered, seamless construction of exceptional clean-line character. This is the necklace that earns its place as the most considered statement piece for any occasion.

Why You'll Love It

• Full-length diamond tennis chain — approximately eighty to one hundred round brilliant white diamonds, each individually four-prong set, arranged in a continuous unbroken sequence along the full chain length, create a necklace of exceptional all-over white diamond brilliance; the full-length construction ensures that the necklace is entirely diamond-covered from every angle, with no plain silver visible across the full length
• Four-prong individual diamond setting — each diamond held by four individual prongs allows each stone’s full round brilliant fire to be visible from above and from the sides simultaneously; the four-prong construction creates a chain of exceptional three-dimensional white diamond brilliance that catches light from every angle as it moves, and the individual prong settings give the chain a sense of considered craftsmanship detail
• Oversized emerald-cut sapphire centre — the oversized emerald cut’s large rectangular table facet maximises the sapphire’s vivid royal blue colour saturation and creates a centre stone of exceptional commanding presence within the continuous white diamond chain; the emerald cut’s clean architectural step-facets create a considered contrast with the chain’s organic round brilliant fire, and the horizontal setting’s wider dimension running across the neckline gives the centre stone a sense of considered breadth and presence
• Seamless centre-set construction — the sapphire is set directly into the chain at its centre point, with no separate bail or pendant mount, giving the necklace a considered, seamless construction of exceptional clean-line character; the seamless construction ensures that the sapphire reads as an integral part of the chain rather than a pendant attached to it, and the clean-line profile sits flush against the neckline
• Guilt-free luxury — lab-grown sapphires share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
