Lab alexandrite. Marquise cut. A color-change solitaire pendant that shifts from teal-green in daylight to purple in incandescent light.

This marquise cut alexandrite necklace features a lab-created alexandrite in an elongated marquise cut set as a solitaire pendant — a stone whose color changes completely with the light source. In daylight or fluorescent light, the alexandrite appears teal-to-green; under incandescent or candlelight, it shifts to purple-to-red. The marquise cut's vertical orientation on a pendant chain positions the stone's longest axis along the neckline, creating an elongated, pointed teardrop silhouette that moves with the wearer and catches light from changing angles throughout the day — making the alexandrite's color shift particularly visible as the stone rotates. Available as pendant only or pendant with chain, in 925 sterling silver, yellow gold plated, or rose gold plated. Handcrafted in Jaipur.

The Alexandrite Effect: Color Change

Alexandrite's color change is caused by chromium within the crystal structure absorbing light in a narrow band of the visible spectrum (yellow-green), transmitting both blue-green and red wavelengths simultaneously. In daylight, blue-green transmission dominates and the stone appears teal or green. Under incandescent light, red transmission dominates and the stone appears purple or red. This shift — sometimes described as "emerald by day, ruby by night" — is one of the rarest optical phenomena in gemology. In a pendant, the stone's movement on the chain means the light angle changes constantly as the wearer moves, creating a particularly dynamic display of the color transition across different lighting environments throughout the day.

Why Marquise Cut for a Pendant?

The marquise cut's elongated pointed silhouette is one of the most distinctive cuts for pendant jewelry. Oriented vertically on a chain, the marquise stone's longest axis runs parallel to the chain's drop, creating a clean, continuous vertical line from chain to pendant tip. The stone's pointed ends draw the eye downward along the neckline, and the cut's large surface area relative to its carat weight means the stone appears larger than a round of the same weight. For an alexandrite specifically, the marquise's broad, open face maximizes the visible surface area through which the color change is displayed — more of the stone's color-shifting interior is visible than in a more compact, heavily faceted cut.

About Lab Alexandrite

Natural alexandrite is one of the rarest and most expensive gemstones in the world — fine specimens regularly exceed diamond in price per carat due to the precise geological conditions required for chromium to substitute within chrysoberyl's crystal structure. Lab-created alexandrite replicates the color-change phenomenon exactly, with the same chromium-based optical mechanism and the same chemical composition as natural alexandrite, making the alexandrite effect fully accessible. Alexandrite is the June birthstone, alongside pearl and moonstone.

Care Instructions

• Remove before swimming, showering, or applying lotions and perfumes (especially for plated finishes)
• Alexandrite is 8.5 Mohs — durable for daily wear; handle with normal care
• Wipe gently with a soft, dry cloth to maintain brilliance
• Store flat in a dry, closed box when not worn to prevent chain tangling
