Lulu keeps the setting quiet around its marquise-cut lab-grown alexandrite. The centre is held in four prongs above a plain platinum band. With no accompanying gemstones, its long, pointed outline is easy to recognise.

This version centres on a lab-grown alexandrite in a marquise cut. The narrow plain band and absence of side stones place the emphasis on the gemstone's tapered shape. Each tapered end contributes to the marquise silhouette. The plain band introduces no competing texture, and four prongs provide the specified setting. This leaves the centre's shape and colour to do most of the visual work.

Platinum gives this Lulu variation a pale metal setting. The plain 1.65mm shank keeps the long gemstone clear of added shoulder detail.

Four marquise options allow the centre's scale to be selected independently of the mount: 8x4mm through 12x6mm. Their weights describe the single lab-grown gemstone. The plain band and four-prong setting remain the shared design.

The result is a narrow-banded solitaire in which one alexandrite carries the full visual emphasis. Size changes the centre's scale without changing its basic cut or plain shank.

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.
