0.37 Ct. Alexandrite from Ceylon (Sri Lanka)

This 0.37 carat oval shape alexandrite from Ceylon Sri Lanka exhibits a precise set of proportions at 4.31 x 3.29 x 3.19 mm, cut in a mixed brilliant fashion to balance faceted brilliance with color saturation. The mixed brilliant cut combines a faceted crown optimized for spectral dispersion with a pavilion geometry that promotes efficient light return, resulting in lively scintillation despite the small table. Clarity grade is very very slightly included evaluated at eye level, and the stone benefits from an excellent polish that enhances facet definition and windowing control. Color intensity is classified as intense, showing a clear alexandrite color change from yellowish green under fluorescent lighting to brownish orange under incandescent lighting, a transition produced by chromium related absorption in the visible spectrum. There is no enhancement, the piece is natural, and the precise cutting preserves weight while maximizing color performance and durability for mounted use.

From a jewelry design perspective this oval alexandrite is highly versatile, and The Natural Gemstone Company can customize it into a wide range of settings to suit both traditional and contemporary aesthetics. The compact 4.31 x 3.29 x 3.19 mm profile is ideal for delicate solitaire rings with a low profile prong setting, halo rings that use melee diamonds to intensify apparent size and color contrast, and three stone arrangements where the alexandrite serves as the primary accent. For everyday wear options, bezel and rubover mountings provide metal protection to the girdle and improve retention, while cathedral shoulders and split shank designs can visually enlarge the stone. Modern settings such as tension mountings and east west orientations emphasize the color change and faceting pattern, while pairing with warm metals like rose gold or yellow gold will enhance the brownish orange shift, and white metals like platinum or white gold will emphasize the yellowish green aspect. Additional customization services from The Natural Gemstone Company include precision setting tolerances, micro pave surrounds, millgrain finishing, and bespoke design consultations to integrate this alexandrite into earrings, pendants, cluster pieces, and engagement compositions, ensuring technical harmony between the stone geometry and the selected mounting.
