0.38 Ct.Tw.Total Carat Weight Alexandrite Pair from Ceylon (Sri Lanka)

This matched pair of natural alexandrite gemstones from Ceylon Sri Lanka presents a rare combination of transparency, precision cutting, and authentic color change. The two stones weigh 0.18 carats and 0.20 carats respectively, and are fashioned into classic oval shapes with dimensions of 3.96 x 3.06 x 1.95 mm and 4.08 x 3.01 x 1.77 mm. Each stone has been cut in a mixed brilliant style to balance table sparkle with pavilion depth, and both exhibit an excellent polish that enhances light return. Clarity is graded as very, very slightly included, evaluated at eye level, which renders them effectively eye clean while retaining the natural character expected from fine alexandrite. These stones are unenhanced, with no treatments applied to alter color or clarity, and their origin from Ceylon Sri Lanka is notable for producing pieces with refined tone and stable crystallographic qualities.

Optical behavior is central to the appeal of these alexandrites, and this pair displays a perceptible transition from green under fluorescent lighting to brown under incandescent lighting, reflecting the classic pleochroic tendencies of alexandrite group chrysoberyl. Color intensity is described as medium and the tonal shift is even across each stone, which allows designers to exploit this phenomenon in pieces that interact with changing light throughout the day. The mixed brilliant cut, combined with the very slight inclusions and excellent polish, contributes to lively scintillation and controlled dispersion, producing a sophisticated play of color without appearing overly saturated. The stones are transparent and exhibit consistent facet symmetry, traits that support fine jewelry applications where optical performance and durability are required.

These matched alexandrites are particularly well suited to personalized designs that take advantage of their paired nature and color changing properties. As a matched set they are an ideal choice for stud or drop earrings, where symmetry and coordinated light response are important. For bespoke ring concepts these stones lend themselves to three stone layouts, twin center stones in a bypass setting, or offset paired motifs that emphasize the color shift when the hand moves through different lighting. In pendant form a horizontal or vertical paired configuration can create a subtle narrative of light, while halo or milgrain treatments can be tailored to heighten the perceived color depth. Given the slight difference in weight and dimensions, design approaches that respect their individuality while maintaining visual balance will yield the most harmonious results. Metal choices such as platinum, 18k yellow gold, and 18k rose gold will influence the perceived warmth of the brown phase or the crispness of the green phase, enabling targeted customization for the wearer.

The Natural Gemstone Company provides these alexandrites as natural, untreated gemstones with clear provenance from Ceylon Sri Lanka, and we support clients seeking bespoke settings by offering detailed measurements, high resolution imagery, and consultation on mounting styles that enhance both protection and presentation. For everyday wear we recommend secure prong or bezel settings with appropriate seat depth to protect the girdle and pavilion, and occasional professional cleaning to maintain polish and optical performance. Because alexandrite is a durable gemstone suitable for most jewelry types, thoughtful design can balance aesthetic expression with long term wearability.
