0.34 Ct. Alexandrite from Ceylon (Sri Lanka)

One beautiful transparent 0.34 carat oval shape alexandrite, dimensions 4.14 by 3.24 by 3.07 mm, mixed brilliant cut, clarity grade very slightly included as evaluated at eye level, intense color intensity, excellent polish, no enhancement, origin Ceylon Sri Lanka, offered by The Natural Gemstone Company. This alexandrite presents as a classic example of natural color change chrysoberyl, combining a compact yet well proportioned oval outline with modern mixed brilliant faceting that maximizes return of light from the crown while preserving strong body color. The carat weight of 0.34 places this stone in the desirable small to medium range for fine custom jewelry, where exceptional color and optical performance matter more than sheer size. The very slightly included clarity grade means inclusions are minimal and are not readily visible to the unaided eye at normal viewing distances, which sustains strong transparency and contributes to lively sparkle and scintillation, while the excellent polish ensures crisp facet junctions and strong light reflection.

The most compelling attribute of this alexandrite is its intense color change, shifting from a fresh green under fluorescent lighting to a warm brownish yellow under incandescent lighting. This phenomenon is characteristic of true alexandrite and results from trace chromium with complementary interactions from background iron and other elements within the chrysoberyl matrix, producing wavelength selective absorption that yields the striking color shift. Under cooler light sources the gem exhibits a vivid green that reads as both saturated and deep, while under warmer light the stone moves toward an autumnal brownish yellow that carries a soft honey tone without becoming muddy. For the educated buyer, this balanced and intense change is a central indicator of desirability, because stones that show strong, clean shifts across common lighting conditions are notably rarer than stones with only subtle or muted changes. The Ceylon origin offers a distinct profile, often favoring lively greens and warm yellow to brown shifts, and represents an important segment of alexandrite provenance that is both historically respected and accessible in quality that rivals the finest material from other localities.

The mixed brilliant cut is a practical choice for a small oval alexandrite, because the combination of brilliant crown facets and modified pavilion geometry preserves strong light return while concentrating color in the table and crown facets for maximum visual impact. Because alexandrite is a chrysoberyl with a Mohs hardness of approximately 8.5, it is durable enough for regular wear when set properly, and the excellent polish enhances resistance to surface wear and preserves luster over time. The very slightly included clarity grade indicates that the stone is effectively eye clean, which maintains brilliance and contributes to a clean field when paired with accent stones. In custom design, this alexandrite performs exceptionally well as a center stone in a classic four prong or secure bezel setting. A delicate halo of white diamonds in small melee sizes ranging from 0.01 to 0.02 carat each will amplify the perceived size and provide high contrast that emphasizes the color change. For a refined aesthetic, tapered baguette or trillion cut side stones in white diamond provide structural balance without competing with the central color change. If you prefer colored accents, choose stones that are chemically stable and well matched for tone. Untreated green tsavorite garnets can enhance the green phase, while soft pink sapphires or rubellites can offer a warm contrast against the brownish yellow phase, creating a dynamic interaction with the alexandrite under varied lighting.

When considering metal and overall color palette for a bespoke piece, the metal choice materially affects how the alexandrite reads in daily wear. Platinum or white gold will emphasize cooler green tones and present a contemporary, high contrast look. Eighteen karat yellow gold or rose gold will warm the presentation and favour the brownish yellow phase, resulting in a richer, vintage inspired appearance. For an engagement ring that celebrates the stone as a center of chromatic drama, a simple solitaire with low profile claws will allow the stone to show its full color change while remaining secure. For a pendant, a bezel with a high polish rim will offer protection and a framed view that shifts beautifully as the wearer moves through different light sources. For custom suites such as matching rings or earrings, consider sourcing paired alexandrites with similar color change characteristics, or design complementary pieces using small matching sapphires and diamonds to create cohesive collections that read consistently under both natural and artificial light.

The Natural Gemstone Company can support your custom project from design consultation through final setting, and we can assist with additional services such as optional independent laboratory certification for grading and origin verification when desired. For an educated buyer, documentation that confirms the stone is natural, unheated, and from Ceylon Sri Lanka adds provenance and liquidity value. Care for alexandrite is straightforward, avoid exposure to harsh chemicals and strong mechanical knocks, clean with warm soapy water and a soft brush, and avoid ultrasonic cleaners if the mounting has delicate prongs or if there are mixed gemstones that could be sensitive. Store the alexandrite separately from harder stones to prevent abrasion. If you would like design sketches, metal recommendations, or a simulated mock up showing the alexandrite paired with different accent stones, The Natural Gemstone Company is available to provide realistic renderings and expert guidance to ensure the finished piece showcases the color change, intense saturation, and excellent polish of this fine 0.34 carat Ceylon alexandrite.
