Bella Oval Cut Alexandrite Engagement Ring Set in 14K Solid Rose Gold

The Bella is an oval alexandrite engagement ring and matching band built around a two-carat secret: a lab-grown alexandrite that lives as bluish green in the daylight hours and turns purplish red when the candles come out. Set in blushing solid rose gold with your choice of moissanite or natural diamond accents, this alexandrite ring rose gold pairing belongs to our most romantic alexandrite engagement rings, made for a love that shows new colors the longer you look.

Why the oval earns its reputation

An oval does two generous things at once: its elongated outline makes the finger look longer and leaner, and its spread carries more visible face-up size than a round stone of the same weight. At 7 x 9 mm and roughly two carats, the Bella’s center stone has real presence without ever feeling heavy on the hand — the reason ovals anchor so many of our oval engagement rings. The soft curve of the shape also echoes the rounded warmth of rose gold, so nothing about the design sits at hard angles.

A stone that keeps a second color

Alexandrite is one of the very few gemstones with a true color change. In daylight or office light the oval reads bluish green; under incandescent bulbs or candlelight it crosses into purplish red. Because rose gold leans warm, the evening shift feels especially at home here — stone and metal glowing in the same direction. Alexandrite is also the modern June birthstone, which our June birthstone guide explores in full, making the Bella doubly meaningful for a June birthday or anniversary.

Lab-grown alexandrite, the honest way to own one

Natural alexandrite is among the rarest gemstones on earth, which is why fine mined examples cost more than diamonds. The Bella’s center stone is lab-grown alexandrite — genuinely alexandrite, with the identical chemistry, the identical color change, and the same durable 8.5 Mohs hardness, grown above ground instead of mined. Our guide to lab-grown vs natural alexandrite lays out exactly what changes and what does not.

Your sparkle, your choice

The accent stones come in two options, selected from the drop-down menu. Moissanite accents are D color and VVS1 clarity with fiery, rainbow-leaning brilliance at 9 on the Mohs scale. Natural diamond accents are G/H color, I1 eye-clean clarity, conflict-free, and the hardest gemstone there is at Mohs 10. Both read as crisp white light against the color-shifting center — the choice is simply fire versus tradition.

Solid rose gold, in three karats

Every ring in this set is solid rose gold through and through — no plating, no base metal. Choose 10K for the hardest and most affordable option, 14K for our most popular balance of warm color and everyday durability, or 18K for the richest, deepest blush. The 10K vs 14K vs 18K karat guide compares them side by side, and you can see how the finished set fits among our wedding ring sets for women and other rose gold rings.

Sizing & care

Select your size from the drop-down — half and quarter sizes are offered — and check our ring sizing guide first, because measurements can differ by up to half a size between jewelers’ tools. Alexandrite’s 8.5 hardness makes daily wear easy: wash the set occasionally in warm water with mild soap, dry with a soft cloth, and take the rings off for gym sessions, gardening, and harsh cleaning chemicals. The rose gold needs nothing more than the same gentle habit.
