A brilliant-round alexandrite leads this 18k yellow gold Catalina ring. Four prongs frame the centre above a lotus-style basket, while scalloped pavé work follows the narrow shoulders.

A lab-grown alexandrite sits at the centre in a brilliant-round cut. Four prongs hold that circular gemstone over the shoulder setting. The design gives the coloured stone prominence without a surrounding halo.

Yellow gold brings a warm line beneath the coloured centre. Its colour comes from the metal, while the gemstone supplies the separate focal hue above it.

Micro pavé on the scalloped shoulders provides a smaller scale of detail beside the round centre. The 1.70mm band stays narrow, so the four-prong setting and chosen gemstone diameter remain easy to distinguish.

Yellow gold continues through the slim shank and four-prong mount. The warm metal remains visible beneath the basket, while the selected gemstone determines the ring's centre colour and the width of its round face.

The twelve centre sizes extend from 0.32ct / 4.0mm to 4.69ct / 10.0mm. Both carat weight and millimetre diameter appear on each option. The lotus-style basket and shoulder setting continue across the listed range.

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.
