1.32 Ct. Cabochon Alexandrite from Ceylon (Sri Lanka)

This listing describes a natural alexandrite sourced from Ceylon, Sri Lanka, offered by The Natural Gemstone Company. The stone is a cabochon cut oval, weighing 1.32 carats, with dimensions of 6.48 x 6.05 x 3.33 mm. The gem is translucent and displays a color change effect, shifting from a green tone in daylight conditions to a purplish red under incandescent lighting. The color intensity is assessed as medium intense and the polish is graded excellent, resulting in a smooth, reflective surface typical of well executed cabochons. Clarity is reported as very slightly included when evaluated at eye level, with inclusions that are visible under close inspection but do not materially affect the gem's overall appearance or structural integrity. There has been no enhancement to this alexandrite, and it is supplied with certification recorded as Other, with the lab color classification noted as color change.

The color change phenomenon in this alexandrite is characteristic of chrysoberyl alexandrite and is caused by the interaction of chromium and other trace elements with the visible spectrum, producing a distinct shift between green and purplish red depending on the lighting environment. Under neutral to daylight type lighting the gem presents a clear green hue, while incandescent or warm light induces a more purplish red presentation, as illustrated by the included images. The cabochon cut accentuates the color transition by presenting a continuous, undivided field of color, and the oval shape provides balanced face up coverage for mounting. The medium intense saturation delivers a perceptible and attractive change without appearing overly dark, and the excellent polish enhances the optical uniformity of the surface. The very slightly included clarity grade indicates natural internal characteristics consistent with a natural origin and with the lack of enhancement, confirming the stone is in its natural state.

From a practical standpoint this alexandrite is suitable for a variety of jewelry applications, including rings, pendants, and earrings, with consideration given to protective settings for daily wear. Alexandrite is a durable gem species with a high hardness, making it well suited to secure settings, while the cabochon profile benefits from bezel or partial bezel mountings that protect the girdle and dome. Conservation and care recommendations include avoiding exposure to harsh chemicals, strong acids or prolonged extreme heat, and cleaning with mild soap and warm water followed by gentle brushing when necessary. Professional ultrasonic cleaning is typically acceptable for well cut, unenhanced chrysoberyl, but confirmation with your jeweler is advised prior to use. The Natural Gemstone Company can provide certificate details and additional photographs or measurement verification upon request, and we can advise on mounting options and custom settings to preserve the gem quality while achieving the desired aesthetic.
