This is the ring that stops conversations.

What You Get That They Don't Offer

• 2.5 carat blue emerald cut with hidden halo — blue emerald cuts are nearly impossible to find at competitors. Blue is the rarest and most expensive fancy color, and emerald cuts in blue are virtually nonexistent in their inventories
• 44 accent diamonds including hidden halo — the hidden halo creates a crown of sparkle beneath the blue center, visible from the side for a dramatic reveal
• The emerald cut transforms blue into something architectural — the step-cut facets create deep planes of color like looking into still water. No other cut showcases blue with this kind of depth
• Blue emerald in white gold or platinum creates an ice-cold, regal presence that feels like wearing a piece of the ocean
• Lab-grown technology makes a 2.5-carat blue emerald diamond accessible — a mined equivalent would cost tens of thousands
• Three metal karat options including 10K — competitors don't offer this entry point
• Insurance included at no additional cost
