8.17 Ct. Cabochon Alexandrite from Russia

This translucent 8.17 carat oval alexandrite measures 14.07 x 10.19 x 5.64 mm, and presents a cabochon cut that emphasizes body color and color change over faceted brilliance. The material exhibits a bluish to purplish hue with dark color intensity, and has been graded slightly included when viewed at eye level. The surface shows an excellent polish, and the stone is untreated with no enhancement. The documented origin is Russia, a source known for classic alexandrite material with strong color change properties and stable crystalline structure. These objective attributes combine to produce a gem that reads as substantial in both physical presence and visual weight, suitable for secure settings that protect the cabochon dome while allowing light to interact across the curved surface.

Under natural daylight and cool northern light the stone tends toward its cooler blue side, displaying a clear bluish cast that reads as deep and saturated due to the dark tone. The translucency allows internal light transmission, so the cabochon manifests a soft, even glow rather than sharp facet sparkle. In warm incandescent or candlelight environments the alexandrite shifts toward a purplish cast, with the darker intensity lending a rich, velvety appearance to the color. Under modern LED lighting the result depends on the LED color temperature, cooler white LEDs will favor the bluish aspect, while warm white LEDs will bring forward the purplish tones. Fluorescent lighting will often produce an intermediate effect, moderating the change and yielding a balanced teal to lavender nuance. Because the cut is cabochon, the visual transition between lighting conditions is smooth and immersive, appearing as a broad color change across the dome rather than localized flashes. Slight inclusions assessed at eye level may be visible in raking light, adding character without materially diminishing the gem's visual appeal.

For practical handling and setting the stone benefits from designs that protect the domed profile while allowing exposure to ambient light. A bezel or protective prong setting with a slightly raised gallery will preserve the cabochon and permit the best expression of color change as the wearer moves through different lighting environments. Routine care using warm soapy water and a soft brush is appropriate, avoiding harsh chemicals and ultrasonic cleaning that can stress surface polish. The Natural Gemstone Company provides this alexandrite as a documented, natural, and untreated example of classic Russian material, and the provided specifications reflect measured dimensions, weight, clarity, and finish for informed evaluation and selection.
