Esme holds an emerald-cut lab-grown alexandrite within a visible diamond halo in rose gold. The cut gives the centre a longer, angular outline; it does not mean the gemstone is an emerald. Diamonds along the shoulders lead towards the single coloured stone.

The centre remains the broadest area of colour from above, while smaller diamonds provide a separate frame. Its straight sides and clipped corners stay distinct inside the halo. The shoulder detail makes this more layered than a plain solitaire without adding another coloured centre.

Rose gold brings a warm metal finish to the diamond setting. The band measures 2.10mm according to the specification, carrying the shoulder stones towards the halo. The centre and its surrounding diamonds have different roles in the design.

Seven alexandrite centre sizes are listed from 5x3mm to 11x9mm. Each variant gives the weight of the individual lab-grown gemstone rather than a combined halo weight. The dimensions show both the length and width of the emerald-cut centre.

This Esme ring uses cut, colour and setting as separate elements: an alexandrite gemstone, an emerald-cut outline and a diamond halo. It is listed as fitting most standard wedding bands.

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.
