1.17 Ct. Cabochon Alexandrite from Ceylon (Sri Lanka)

This finely proportioned 1.17 carat round shape greenish to reddish alexandrite measures 6.23 x 6.11 x 3.19 mm, and it presents as a cabochon cut with a high domed profile, translucent body, and a vivid color intensity. The cabochon form emphasizes broad color fields rather than facet derived scintillation, and the dome has been shaped and polished to precise symmetry, preserving the round outline and centering the visual axis. Clarity is graded very very slightly included when evaluated at eye level, which means that inclusions are minimal and do not interrupt the surface or overall visual impact under normal viewing conditions. The polish is excellent, creating a smooth, reflective surface that accentuates the stone s depth and color transition, and there has been no enhancement applied to the material. Origin is Ceylon Sri Lanka, a provenance known for alexandrite specimens that combine chromatic richness with fine crystalline structure, and The Natural Gemstone Company stands behind this stone with full disclosure of its natural state.

The cabochon cut is a technical choice that enhances alexandrite s characteristic color change, and the dome geometry interacts with transmitted and reflected light to produce a strong and uniform shift from greenish tones in cool, daylight dominated sources to reddish tones in incandescent or warm light. Unlike faceted stones where facet angles and pavilion depths modulate sparkle and color zoning, a well executed cabochon maximizes the continuous field of color and allows the observer to appreciate subtle pleochroic effects and dichroic contrast. The translucent nature of this piece permits light to penetrate, scatter, and reflect from internal planes, which in conjunction with the vivid color intensity yields saturated color without appearing opaque. The very very slightly included clarity grading indicates that any internal features are minute and typically restricted to needlelike or crystal remnants, they act as internal markers rather than detractors, and their presence confirms natural growth rather than treatment. The excellent polish and the careful control of the dome curvature reduce surface diffusion and ensure crisp transitions between color states, while the absence of enhancement guarantees that the observed chromatic performance is intrinsic to the material.

Craftsmanship extends beyond the cut into considerations of wearability, stability, and long term beauty, and alexandrite s hardness and toughness make it well suited for regular wear when set with appropriate protection. On the Mohs scale alexandrite is approximately 8.5 which confers resistance to scratches from everyday contact, and the cabochon dome further protects internal features while offering a timeless aesthetic. From a conservation perspective the stone s color centers are stable under normal environmental conditions because the chromophore responsible for the alexandrite effect is an inherent part of the crystal lattice, and because there has been no heat treatment or diffusion applied, the color and clarity will remain consistent over the years. When set in jewelry a bezel or partial bezel setting is recommended to shield the girdle and protect the dome from knocks while allowing sufficient exposure to light so that the greenish to reddish transition remains visually dynamic. The provenance from Ceylon Sri Lanka, combined with the natural, untreated state and the exacting workmanship represented by the cut and polish, ensures that this alexandrite will continue to captivate collectors and connoisseurs alike, delivering a rare balance of scientific interest and aesthetic pleasure. The Natural Gemstone Company is pleased to present this piece to clients who value precise craftsmanship, documented origin, and a natural gem that will age with dignity and ongoing visual intrigue.
