Eva Lab-Grown Alexandrite Flower Engagement Ring in 14K Solid Rose Gold

A lotus opens twice a day — and so does the Eva. Petals of moissanite or natural diamond unfold around an oval lab-grown alexandrite that blooms bluish green in daylight and closes the evening in purplish red. This alexandrite ring in solid rose gold turns a rare color-change gem into a flower that is always in season.

A lotus rendered in rose gold

The Eva’s setting is drawn from the lotus blossom, a flower that closes at dusk and reopens with the sun — a fitting frame for a stone that also changes with the light. A ring of accent stones fans out beneath the center gem like petals, in your choice of D-color VVS1 moissanite or natural G/H diamonds, all conflict-free. The slender 1.8 mm band keeps the bloom in focus, giving the Eva a delicacy that stands out even among our floral engagement rings and the wider world of nature-inspired engagement rings.

The oval cut, made for color

At its heart sits a 7 x 9 mm oval lab-grown alexandrite of approximately 1.4 carats. The elongated oval gives alexandrite a generous face to perform on: cool bluish green under daylight, warming through violet into purplish red under candlelight and indoor bulbs. The effect is not a coating or a trick of the setting — it is the stone itself absorbing light differently by source, and our article on how lab-grown alexandrite changes color explains exactly what to expect. An oval also wears larger than a round of the same weight and flatters the finger, virtues it shares with the best of our oval engagement rings.

Solid rose gold, three karats

Every Eva is made to order in solid rose gold — choose your karat from the drop-down menu:

• 10K rose gold — the hardest and most durable of the three, and the most affordable way to own this design.
• 14K rose gold — the most popular all-rounder, balancing everyday durability with a rich, warm rose hue.
• 18K rose gold — the warmest color and the highest gold content, for a truly luxurious finish.

Not sure which to pick? Our 10K vs 14K vs 18K karat guide breaks the choice down clearly.

Petals of moissanite or diamond

Both accent options earn their place in the bloom. Moissanite is a real lab-grown gemstone in its own right — D color, VVS1 clarity, rated 9 on the Mohs scale, with even more fire than diamond; our guide to whether moissanite is a lab-grown diamond clears up the difference. The natural diamond option brings G/H color, eye-clean I1 clarity, and conflict-free sourcing. Either way, the petals catch light from every angle while the alexandrite does its slower, stranger magic in the middle.

A symbol of rebirth and transformation

The lotus has meant rebirth and resilience across cultures for millennia: it rises from still water and opens fresh every morning. Alexandrite, for its part, is the gem of transformation and good fortune. Together they make the Eva an engagement ring with a story built in — a love that keeps opening. It is one of the most distinctive designs in our alexandrite engagement rings collection, and a memorable alternative to more conventional sparkle.

Sizing & care

Select your size from the drop-down menu — half and quarter sizes are offered — and measure at home with our ring size guide. Sizing tools differ slightly between jewelers, so readings can vary by up to half a size. Alexandrite’s 8.5 Mohs hardness makes the Eva an easy daily companion: wash it occasionally with warm water, mild soap, and a soft brush, dry it gently, and store it apart from diamonds and other harder stones. The slender band appreciates being removed for gym sessions and heavy lifting. Your ring ships free within the USA in a complimentary luxury ring box.
