Clean, modern lines let the stone do the talking — teal-green in daylight, warm purple under lamplight — for an engagement ring or meaningful gift that looks like nothing else. Color-change alexandrite Triangle cut Minimalist solitaire Lab-grown Solid rose gold Made to order The color-change alexandrite At the center is a triangle-cut lab-grown alexandrite, about 6.0×6.0 mm and 1.0 carat. Alexandrite is famous for its color change: it reads cool teal-green in daylight and shifts to a warm purple or raspberry under incandescent light. This is a lab-grown (lab-created) alexandrite — the same chrysoberyl mineral and dramatic color shift as the exceptionally rare natural stone, grown ethically for consistent color and clarity at a fraction of the cost. A minimalist triangle solitaire The triangle (trillion) cut is an unusual, geometric choice that suits the ring's pared-back design. With a slim band and no side stones to compete, the setting keeps all attention on the alexandrite and its shifting color. Alexandrite is Mohs 8.5 — genuinely hard and well suited to everyday wear. Choose your metal & karat The ring is made in solid rose gold — never plated or filled — so the warm blush runs all the way through and won't wear off. Choose the karat that suits you: 10K Rose GoldMost affordable · hardest 14K Rose GoldPopular balance 18K Rose GoldPremium · more pure gold Rose gold gets its warm color from a copper alloy, and higher karats hold more pure gold while lower karats are a touch harder.

Frequently asked questions Is the alexandrite natural or lab-grown?It's lab-grown (lab-created) — the same chrysoberyl mineral and color-change effect as natural alexandrite, grown ethically for consistent color and clarity. Natural alexandrite is one of the rarest and most expensive gems, so a lab-grown stone gives you the same beauty at a fraction of the cost. Does it really change color?Yes.

What is a triangle (trillion) cut?It's a triangular gemstone cut with three sides, giving a clean, geometric, modern look that stands apart from a traditional round solitaire.
