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

These two transparent alexandrites offered by The Natural Gemstone Company are presented as a matched pair, weighing 0.83 carats and 0.79 carats respectively, with oval shapes that measure 6.72 x 4.82 x 3.40 millimeters and 6.61 x 4.84 x 3.51 millimeters. Both stones are mixed brilliant cut, exhibiting excellent polish and a vivid color intensity that is immediately apparent in both studio and natural photography. The material is natural chrysoberyl alexandrite from Ceylon Sri Lanka, and there has been no enhancement applied to either gem. At eye level these stones are graded as eye clean, which means no inclusions are visible to the unaided eye under normal observation, a notable attribute for alexandrite of this size and color quality. The pair demonstrates the classic alexandrite color change, appearing greenish blue under fluorescent or daylight sources and shifting to a strong purple under incandescent lighting, a phenomenon produced by chromium substituting into the chrysoberyl structure and filtering visible wavelengths differently under varying light sources.

From a gemological and craftsmanship perspective, the value of this pair is rooted in the precision of matching and the skill applied in cutting to maximize the color change and optical performance. The cutter chose a mixed brilliant faceting scheme to balance color concentration and light return, which is critical for alexandrite because overly shallow or overly deep proportions can mute the color change or sacrifice brilliance. These two stones are closely matched in weight within 0.04 carat, and their dimensions and table and pavilion relationships were adjusted to ensure consistent face up appearance and similar color behavior in both daylight and incandescent conditions. The excellent polish contributes to crisp facet junctions and strong light return, enhancing perceived saturation and sparkle. For an educated buyer, these attributes indicate careful selection and skilled lapidary work, because achieving a uniform color change and matching proportions across a pair requires sorting rough material with compatible color zoning and then cutting with intentional symmetry and depth control.

Practical considerations for placement and long term enjoyment further support the appeal of this matched alexandrite pair. Alexandrite is chrysoberyl, which rates approximately 8.5 on the Mohs hardness scale, giving it excellent durability for daily wear in earring settings, rings with protective bezels, or bespoke matched pieces such as a pendant and earring set. The untreated origin in Ceylon Sri Lanka increases desirability for collectors who prioritize provenance and natural color, and the eye clean clarity means the gems will display their full color potential without internal features interrupting light. Recommended settings are those that allow enough light to interact with the stones, such as open prong or light enhancing bezel designs, while also protecting the girdle and pavilion from knocks. In summary, this pair represents a thoughtfully matched, natural, untreated example of alexandrite with strong color change, excellent polish, and eye clean clarity, and it exemplifies the kind of careful sourcing and lapidary craftsmanship that The Natural Gemstone Company emphasizes when curating gemstones for discerning buyers.
