Lab Blue Sapphire Round Brilliant Halo Pendant Necklace in 925 Sterling Silver

Deep royal blue, ringed in white — the pendant format that has been the definitive everyday fine jewellery piece for good reason.

This pendant is the round brilliant halo in its most resolved form: a large round-cut lab-grown blue sapphire in deep royal blue, set within a single full halo of round brilliant white stones that traces the circular outline of the sapphire with precise, even spacing. Round brilliant cut on round brilliant halo is the most compositionally unified pendant format available — the circular sapphire and its circular white stone frame share the same geometry, and the result is a pendant that is immediately and completely readable as a composed object from any distance. The round brilliant cut delivers the maximum light return of any cut format: 58 facets arranged to direct all available light back through the table of the stone, producing the characteristic star-burst internal reflection pattern visible at the centre of the sapphire in the image. In deep royal blue, this internal light return creates the optical quality that makes a fine blue sapphire unmistakable — a vivid, luminous blue with internal movement rather than a flat colour. The single halo of individually-set round brilliant white stones surrounding the sapphire increases the apparent diameter of the pendant face and creates a clean white brilliance border that amplifies the deep blue by contrast. The pendant is set in four silver prongs on a simple bail and hangs on a fine 925 sterling silver cable chain that keeps the pendant face-forward at the collarbone. At $198, this is the pendant that works every day, with everything, and never requires justification.

Why You'll Love It

• Round brilliant sapphire — maximum light return — the round brilliant cut’s 58-facet arrangement is optimised to direct all available light back through the stone table; in deep royal blue, this produces the characteristic internal star-burst reflection and luminous blue with internal movement that defines a fine blue sapphire
• Deep royal blue — the benchmark sapphire colour — deep royal blue is the most universally recognised and valued sapphire colour; it reads immediately as a fine gemstone at pendant-glance distance and creates a clean, strong colour contrast against the white stone halo and 925 silver setting
• Round-on-round halo — the most unified pendant composition — a circular sapphire within a circular white stone halo creates the most compositionally resolved pendant format; both elements share the same geometry, producing a pendant that reads as a single complete object rather than stone plus surround
• Single halo amplifies apparent size — the ring of individually-set round brilliant white stones increases the visible diameter of the pendant face beyond the sapphire alone; the white stone border also creates a contrast frame that makes the deep blue appear more vivid and saturated at its centre
• The pendant that works every day — the round brilliant sapphire halo pendant sits flat at the collarbone, catches light at every angle of movement, layers with other pendants or sits alone, and transitions from work to occasion without requiring a styling decision; it is the most versatile single pendant format in fine jewellery
