Lab Sapphire Emerald Cut Three-Stone Adjustable Ring in 925 Sterling Silver

Deep navy blue, clean lines, no apologies — a ring that means exactly what it looks like.

This three-stone ring centres a large emerald-cut lab-grown sapphire in a deep, ink-blue tone, flanked by two trapezoid-cut white side stones that mirror the rectangular geometry of the centre stone precisely. A pair of small round brilliant stones sit at each shoulder, adding a subtle sparkle that transitions smoothly into the plain, polished 925 sterling silver band. The emerald cut is chosen deliberately here — its step-cut facets create broad flashes of deep blue rather than scattered sparkle, giving the stone a commanding, almost architectural presence. The open-back adjustable band means this ring fits a range of finger sizes without compromising the clean silhouette from the front. Understated, considered, and built to last.

Why You'll Love It

• Emerald-cut lab sapphire — the rectangular step cut maximises the stone’s deep navy colour across a broad, open face; bold and architectural rather than fussy
• Trapezoid side stones — the tapered rectangular side stones echo the emerald cut’s geometry, creating a cohesive three-stone composition with real visual intelligence
• Open-back adjustable band — fits a range of finger sizes comfortably without altering the ring’s clean front profile
• 925 sterling silver, polished finish — hypoallergenic, durable, and refined; the plain band keeps the focus entirely on the stones
• Versatile enough for daily wear, distinctive enough to matter — the three-stone format reads as both a personal statement and a considered gift
