Square Lab-Grown Alexandrite Pendant

A 5 by 5 mm square alexandrite turned on point and held at its four corners, with no frame and no halo. Every other solitaire in this group of designs is round; this is the one that is not.

Setting a square on its diagonal is the reason a 9.1 mm pendant reads larger than its measurements. Corner prongs are also the right engineering choice - a square cut is most vulnerable exactly where the metal is.

The graduation or promotion piece: enough stone to register across a room, no ornament asking to be interpreted.

Alexandrite changes colour with the light it is under: bluish-green in daylight and cool office light, warmer purplish-red under incandescent lamps and candlelight. Supplier imagery is a rendered representation and shows the stone in one colour state, so pieces across this collection are shown in different states. The stone is doing what alexandrite does.

The alexandrite is lab-grown. It is the same species and chemistry as mined alexandrite, the colour-change variety of chrysoberyl, with the same hardness and the same colour-change behaviour, and it is disclosed as lab-grown here, on the product page and on the invoice.

Gemstone carat weights are nominal totals and are approximate; actual weight may vary slightly from the stated figure. Millimetre measurements are nominal and vary piece to piece within normal manufacturing tolerance.

Sold as the pendant on its own — no chain. Pair it with a chain you already own, or shop the matching necklace version.
