2.75 Ct. Cabochon Alexandrite from Ceylon (Sri Lanka)

One beautiful translucent 2.75 carat oval shape alexandrite is offered by The Natural Gemstone Company, with dimensions of 8.95 by 7.16 by 4.75 mm, a cabochon cut, a clarity grade of very very slightly included evaluated at eye level, medium color intensity, and an excellent polish, enhancement no enhancement, origin Ceylon Sri Lanka. This gem presents as a classic collector quality cabochon alexandrite, where the rounded dome maximizes the interplay of light and color change that alexandrite is prized for. The weight and proportions are well balanced for a variety of jewelry settings, from a statement ring to a refined pendant. The clarity description of very very slightly included means that at normal viewing distances the stone reads very clean, with only minimal internal features that are not disruptive to the overall appearance, and the excellent polish contributes to a smooth, high gloss surface that emphasizes the gem tone and depth.

Geologically, alexandrite in Sri Lanka forms in metamorphic environments where chromium has substituted into the chrysoberyl lattice, and this chromium content is the primary reason for the color change phenomenon that defines alexandrite. Ceylon localities are respected for producing stones with attractive secondary hues and reliable stability, and an unenhanced alexandrite from this source carries additional market value for discerning buyers who prioritize natural origin and treatment free status. The fact that there is no enhancement is important to collectors and investors because treatments can affect durability, long term stability, and ultimately resale value. The cabochon cut chosen for this piece is intentional, because for a stone with medium color intensity and a translucent body, a cabochon can present the color field as a continuous, glowing surface, rather than faceted flashes, which creates a different visual appeal that educated buyers often seek for alexandrite with color change.

Under different lighting conditions this alexandrite will display the characteristic shift that defines true color change material, however the exact hue and strength of the change depend on the light source spectrum and viewing angle. In strong daylight, which is rich in blue green wavelengths, expect the gem to read as green to bluish green, with the dome showing even saturation across the surface and a cool, clear tone enhanced by the excellent polish. Under fluorescent lighting, the appearance will be similar to daylight but can edge toward cooler green shades, and the photos provided demonstrate how the stone maintains bright green tones under this type of light. When moved to incandescent or warm LED illumination, which is richer in yellow and red wavelengths, the same stone will warm up and show movement into brownish and olive brown tones, producing the green to brown change noted in the description. The cabochon form will yield broad, soft zones of color rather than faceted flashes, and the dome geometry can accentuate any linear highlights or chatoyant like reflections if they are present, creating a luminous band or bright central reflection as the light source moves. Because the clarity is very very slightly included, internal features will not generally disturb the color change, but at certain orientations small inclusions may act as focal points for light, which can add character without detracting from the gem quality. The excellent polish provides strong surface reflection, so under direct lighting the gem will show crisp specular highlights while still presenting saturated body color.

For practical use and long term appreciation, this 2.75 carat Ceylon alexandrite sits in a sweet spot for both wearable jewelry and specialist collections. Its oval cabochon shape and the dimensions of 8.95 by 7.16 by 4.75 mm make it straightforward to set securely while showing a generous color field, and it will look particularly striking when set in slightly open back settings that allow light to interact with the dome, or in closed back settings that emphasize the darker brown tones for a moodier effect. For metal choice, cooler white metals will harmonize with the green face up appearance, while yellow gold can warm the overall presentation and complement the brown shift under warm lighting. Care is standard for chrysoberyl based stones, cleaning with warm soapy water and a soft brush, avoiding harsh chemicals and steam cleaners if the setting contains additional materials or adhesives. For buyers who require documentation, we recommend obtaining a formal identification report from a reputable gem laboratory that will confirm species, origin if determinable, and the absence of treatments, and The Natural Gemstone Company can assist with arranging independent certification or provide detailed photographs and viewing guides to support appraisal and insurance.

In summary, this translucent 2.75 carat oval cabochon alexandrite from Ceylon offers an authentic unenhanced color change experience, with medium color intensity, an excellent polish, and a clarity grade that reads very clean to the eye, attributes that combine to make it an attractive acquisition for the educated buyer. The combination of natural origin, treatment free status, and the cabochon presentation yields a gem that performs beautifully under a range of lighting conditions, showing cool green tones in daylight and warmer brown tones under incandescent light, while the polished dome provides a pleasing luminous quality. The Natural Gemstone Company stands behind the description and is available to provide additional images, viewing advice, and assistance with certification to ensure that this alexandrite meets the expectations of collectors and connoisseurs who appreciate well documented natural gemstones.
