Under daylight it reads teal to blue-green; under warm indoor light or candlelight it swings to raspberry, violet and plum. The effect is real optics — the mineral absorbs light unevenly across the spectrum, so what you see depends entirely on what is illuminating it.\u003c\/p\u003e\n\u003cp\u003eThe shift is \u003cstrong\u003efully visible\u003c\/strong\u003e here. Alexandrite set as crushed inlay under resin cannot show it; a faceted stone in an open prong setting like this one shows it clearly. Our piece on whether synthetic alexandrite changes color explains the mechanism.\u003c\/p\u003e\n\u003cp\u003eThis stone is lab-grown. Natural alexandrite at 5 × 10 mm is among the rarest gemstones on earth and prices accordingly — the lab-grown material has the same chrysoberyl chemistry and the same behavior. Our comparison of lab-grown versus natural alexandrite lays out the trade-offs. It is set north–south, the most elongating orientation, as our guide to marquise engagement rings explains.\u003c\/p\u003e\n\u003ch2\u003eMetal and Stones\u003c\/h2\u003e\n\u003cp\u003eAll three rings are solid 925 sterling silver with a black ruthenium finish — a platinum-group metal that settles to a deep gunmetal rather than a flat black. It is what makes the set read gothic rather than merely dark: the metal recedes and the stones carry the light.\u003c\/p\u003e\n\u003cp\u003eSmaller lab-grown alexandrite marquises flank the center and top the crown band, and they shift with it. The white accents — marquise at the four corners of the frame, pavé along the shoulders, and a round in each star of the contour band — are cubic zirconia. Moissanite or lab-grown diamond accents are available as a custom order.\u003c\/p\u003e\n\u003cp\u003ePart of our alexandrite engagement rings and gothic engagement rings collections, alongside the rest of our black ruthenium jewelry.
