14K Yellow Gold Custom Engagement Ring with Lab-Grown Elongated Hexagon Emerald and Baguette Diamond Accents

This custom engagement ring is centered on a 12x6mm lab-grown elongated hexagon emerald, and the stone commands the room. The color is a vivid, saturated green with a brightness that sets lab-grown emeralds apart from their natural counterparts — no haziness, no included clouds, just clean depth and remarkable clarity from every angle.

The elongated hexagon is an unusual cut, and that's precisely the point. It has the linear geometry of a step cut but with pointed tips above and below that give it a distinctly Art Deco character. The faceting catches light differently than a round or oval, with broad flashes rather than scattered sparkle — it's a stone that draws the eye and holds it.

On each side, a vertical baguette diamond accent sits flush against the girdle of the emerald, their clean rectangular shape echoing the geometry of the center stone without competing with it. It's a restrained choice that works — the baguettes add just enough contrast and brilliance to frame the emerald without pulling focus from the green.

The setting is 14K yellow gold, a deliberate pairing. Warm gold beneath a vivid green emerald is a classic combination with a long history in fine jewelry, and here it gives the ring a richness that cooler metals simply don't deliver. The band is smooth and tapered, keeping everything clean below the setting.

This ring highlights:

• 12x6mm lab-grown elongated hexagon emerald with exceptional color saturation
• Baguette diamond accents on each shoulder
• 14K yellow gold with a tapered, polished band
• A geometric, Art Deco-inspired silhouette built around an uncommon stone shape
• A fully custom engagement ring crafted to order

Lab-grown emeralds at this size and clarity level are genuinely hard to find in a natural stone without a significant budget. The elongated hexagon cut makes this one rarer still — it's a ring that won't show up on anyone else's finger.
