Lab Blue Sapphire Emerald Cut Halo Ring with Pavé Shank in 925 Sterling Silver

Royal blue, four prongs, and a band of white diamonds that runs all the way around — a ring that looks like an engagement ring and wears like one too.

This halo ring centres a large emerald-cut lab-grown blue sapphire in a deep, vivid royal blue, held in four prongs within a full rectangular pavé halo of round brilliant white stones. The halo follows the rectangular outline of the emerald cut precisely, framing the stone’s clean geometry with a continuous border of white light. The ring shank continues the pavé treatment along both shoulders, so diamond coverage extends from the halo all the way around the band — there is no plain metal visible anywhere when the ring is worn face-on. The emerald cut is chosen deliberately: its open, step-cut facets showcase the deep blue across a broad, uninterrupted face, with the wide reflective flashes that rectangular cuts are known for. The result is a ring with the visual presence of a fine sapphire engagement ring, made with a lab-grown stone and priced accordingly.

Why You'll Love It

• Emerald-cut lab blue sapphire — deep royal blue showcased across a broad rectangular face; the step-cut facets deliver wide, dramatic colour flashes that make the stone the undeniable focal point
• Rectangular pavé halo — follows the precise geometry of the emerald cut, creating a clean, symmetrical frame of continuous white brilliance around the centre stone
• Full pavé shank — round brilliant white stones run along both shoulders of the band, so the ring sparkles from every angle and reads as fully set from face-on
• Engagement ring presence — the emerald cut, rectangular halo, and diamond shank combination is a design language borrowed directly from fine sapphire engagement rings; the visual standard is immediately evident
• 925 sterling silver, available in multiple sizes — hypoallergenic, polished, and durable; sized for a proper fit rather than a generic adjustable band
