1.86 Ct.Tw.Total Carat Weight Cabochon Lapis Pair from Afghanistan

This pair of round cabochon blue lapiss presents a carefully matched set suitable for precision jewelry applications. The stones weigh 0.89 carats and 0.97 carats respectively, with measured dimensions of 6.11 x 6.09 x 3.26 mm and 6.22 x 6.22 x 3.46 mm. Both pieces are opaque, exhibit a deep blue field, and have an excellent polish that enhances surface reflection and visual uniformity. Color intensity is recorded as n slash a, and there has been no enhancement to either stone. Origin is Afghanistan, which is consistent with the saturated blue and natural textural variation visible in the material. The cabochon cut produces a smooth domed profile, and the pair shows consistent curvature and mirror quality polish across both domes, enabling a clean, continuous appearance when set side by side.

Pairing these gemstones requires technical precision to preserve visual balance and to meet manufacturing tolerances. The differences in weight and diameter are minimal, and for a balanced earring or stud pair the acceptable tolerances should align with the measured values, namely diameter variance within a few tenths of a millimeter, height variance within approximately 0.2 mm to 0.3 mm, and weight variance within 0.1 carat. Matching considerations include the dome profile radius, color distribution and intensity across each table area, and surface polish quality. For mounting, a full bezel or low bezel setting will protect the cabochon edge while maintaining the visual continuity of the blue surface, and a low cup stud or flush set may be used where a flat back is required. Recommended metals include sterling silver, 14k or 18k gold, where the visual warmth or coolness of the metal can be selected to complement the blue field. The Natural Gemstone Company provides these measurements and quality notes to assist designers and bench jewelers in achieving a symmetrical final piece, and to ensure that the stones integrate seamlessly into precision settings with predictable fit and finish.
