Esme Oval Cut Alexandrite & Black Moissanite Engagement Ring in 14K Solid Rose Gold

The Esme alexandrite black moissanite ring pairs magic with edge: a genuine lab-grown color-changing alexandrite center — green in daylight, purple under warm indoor light — set against bold black moissanite accents in warm solid rose gold, your choice of 10K, 14K, or 18K. Vintage-romantic yet a little dark and modern, it's made for anyone who dreams beyond the ordinary.

The color-changing alexandrite

At the center sits a genuine lab-grown alexandrite, famous for its dramatic color shift — cool green in daylight, soft purplish-red under warm indoor light. Because the stone is faceted and openly set, you can actually watch that shift as the light around you changes. It's a real optical property of the gem, not a coating. Our guide to whether lab-grown alexandrite really changes color explains how it works.

Genuine lab-grown alexandrite + black moissanite

This is 100% genuine lab-grown alexandrite — the same mineral (chrysoberyl) as natural alexandrite with the same color-change, grown in a lab rather than mined, so it's far more attainable than the very rare mined stone. Our lab-grown vs natural alexandrite guide covers the difference. The accents are black moissanite — a bold, opaque black stone that frames the shifting center with dramatic contrast.

Choose your metal

This ring is solid gold — the metal itself, not plating or vermeil over a base metal — and you choose the karat that suits you. The warm blush metal softens the black accents and flatters the alexandrite's shifting hues, and whichever karat you pick the color is permanent: it won't wear off and won't turn your skin green. Our 10K vs 14K vs 18K karat comparison guide walks through the trade-offs.

• 10K rose gold — the hardest and most scratch-resistant, and the most affordable way into solid gold.
• 14K rose gold — our most popular choice and the everyday default: an ideal balance of durability, gold content, and value.
• 18K rose gold — the highest gold content, with the richest, warmest blush tone.
