8.21 Ct.Tw.Total Carat Weight Cabochon Agate Pair from Namibia

This matched pair of pear shaped blue agates presents a clear technical profile for connoisseurs, the stones weigh 3.69 carats and 4.52 carats respectively, with dimensions of 17.22 x 9.57 x 3.89 millimeters and 17.20 x 9.58 x 3.01 millimeters, the cutting style is cabochon with a smooth domed face and well controlled curvature, the material is opaque with characteristic banding and fine layering typical of agate, the color grade reads as medium intense blue with even saturation across the surfaces, clarity is graded very slightly included at eye level indicating only minor natural fissures or mineral inclusions that do not detract from overall visual appeal, the polish is excellent delivering a high gloss luster that accentuates the banding and surface chatoyance, enhancement is dyeing which has been applied to achieve the uniform blue tone, the origin is Namibia which is consistent with the microstructure and inclusion types observed, for buyers interested in opal attributes please note that related opal inventory at The Natural Gemstone Company is categorized as White Opal.

From a lapidary and mounting perspective the cabochon cut emphasizes stability and ease of setting, the dome heights have been optimized to preserve material thickness near the girdle while allowing the narrow apex of the pear to remain free of thin edges, symmetry between the pair is good though the second stone is slightly thinner at three millimeters which affects weight distribution and will influence bezel wall depth for a matched pair setting, the excellent polish was achieved through progressive finer abrasives and final felt and cerium oxide work, dye stability testing under standard light and mild heat has been performed and the dyeing shows normal resistance though prolonged exposure to aggressive solvents and high heat should be avoided, for jewelry applications we recommend low profile bezels or custom collet settings that protect the apex and maintain even pressure across the dome, adhesive setting should be used with caution and only with conservator grade resins when necessary, care instructions include avoiding ultrasonic cleaners and steam, store separately to prevent abrasion, and request documentation for enhancement disclosure, The Natural Gemstone Company stands behind this technical description and can provide additional measurements, high resolution images, and matching options upon request.
