Paris raises an elongated cushion-cut lab-grown alexandrite above a hidden diamond halo in 18k rose gold. The halo is tucked below the coloured centre, giving the ring a distinct detail from the side.

The elongated cushion outline remains the main shape from above. Small diamonds sit lower in the setting, so the halo appears in profile instead of forming a visible border around the gemstone’s upper face.

Rose gold frames the alexandrite with a warm metal tone. The 1.65mm band stays narrow under the centre, keeping the gemstone and its discreet diamond accents in proportion.

A side view reveals the hidden halo beneath the stone. In a top view, the alexandrite’s longer cushion face carries the design, with the diamonds providing a second, finer line below it.

Four listed centre options extend from 7x5mm / 1.12ct to 10x8mm / 4.11ct. Their size and carat labels help compare how far the gemstone extends across the same petite setting.

This Paris design pairs a coloured centre with diamonds that are deliberately less visible from above. Choose the alexandrite size with the slim rose gold band and lower halo position in mind.

    ABOUT YOUR CENTRE GEMSTONE

    Lab-Grown Alexandrite Engagement Rings: Colour and Design

    Lab-grown alexandrite brings a distinctive colour-changing character to an engagement ring. This variety of chrysoberyl can appear bluish-green in some lighting and shift towards purple or reddish tones in others. The strength of the effect varies from stone to stone, so photographs taken in a single light may not show its full appearance.

    What Is a Lab-Grown Alexandrite Gemstone?

    Laboratory-grown alexandrite has the same essential mineral composition as natural alexandrite but is created in controlled conditions. It is not a diamond or a sapphire. Its changing colour is central to its appeal, particularly when paired with bright accent diamonds that provide a consistent contrast as the centre gemstone changes in different light.

    Choosing an Alexandrite Engagement Ring Setting

    An oval alexandrite gives a graceful, elongated outline; a round or cushion shape creates a different balance on the hand. A solitaire keeps the focus on the gemstone, while a diamond halo frames its changing colour. Compare the centre stone’s millimetre measurements, the metal tone and the side profile of the setting when choosing a ring for everyday wear.
