9.80 Ct.Tw.Total Carat Weight Tourmaline Pair from Mozambique

This pair of tourmalines from The Natural Gemstone Company presents an exceptionally well controlled set of cutting and material parameters, each weighing 4.90 carats, oval in outline, and cut to mixed brilliant style. The individual dimensions are closely matched at 12.37 x 9.01 x 7.05 mm and 12.35 x 9.10 x 7.02 mm, demonstrating a tolerance in length and width of less than one tenth of a millimeter, and a depth variance of only a few hundredths of a millimeter. The mixed brilliant cutting approach used here combines a brilliant facet arrangement on the crown with a complementary pavilion faceting scheme that optimizes both scintillation and table brightness for tourmaline. The excellent polish across both stones ensures clean facet junctions and uninterrupted light transmission, and the heat treatment indicated was applied in a controlled manner to stabilize the pinkish brown hue while preserving the material clarity and structural integrity typical of Mozambique origin tourmaline.

Clarity is an important differentiator for matched pairs, and these two stones carry a clarity grade described as very very slightly included when evaluated at eye level, translating to eye cleanliness in normal wear and the presence of only extremely minor inclusions under careful inspection. That level of internal freedom is instrumental in achieving uniform light performance across the pair, because inclusions can act as scattering centers that disrupt brilliance and change apparent color. Here the similarity of inclusion character and distribution between the two stones is evident from the face up appearance, supporting consistent light return and minimizing any perceptible variance in brightness. The excellent polish further reduces surface diffusion of light, allowing the internal clarity quality to translate directly into crisp facet definition and lively scintillation when set.

Color matching in tourmaline is often more technically demanding than matching weight or proportions, because tourmaline exhibits pleochroism and sensitive response to cutting orientation. These two pieces feature a pinkish brown hue at medium color intensity, deliberately chosen and positioned by the cutter to present congruent face up tone and saturation. The mixed brilliant cut was executed with attention to crown angles and table size to balance the warmth of the brown component with the pink overtone, preserving even saturation across the table and pavilion. The heat treatment has been applied to stabilize the medium intensity, reducing uneven zoning and locking in a predictable response under varied lighting. Given the shared origin in Mozambique, both stones show the same base chromophore chemistry, which aids in creating a superior color match and ensures that under common lighting conditions the pair behaves as a harmonious unit rather than two disparate stones.

From a design and setting perspective the pair is a technically superior match suitable for symmetric applications such as earrings or matched set components, because the carat weights are identical and the linear dimensions are effectively identical within industry tolerances. The mixed brilliant proportions deliver a repeatable pavilion angle and crown geometry, so when placed in identical bezels or prongs the optical behavior will be consistent, preserving balanced face up color and equal light return. The combination of very very slightly included clarity evaluated at eye level, medium color intensity, excellent polish, matched proportions, and common heat treatment and provenance from Mozambique makes this pair an exceptional choice for a refined matched set. The Natural Gemstone Company provides these tourmalines with the assurance that both optical and material variables were controlled to yield a pair that performs predictably in fine jewelry, offering both technical precision and aesthetic harmony.
