1.62 Ct.Tw.Total Carat Weight Cabochon Coral Pair from Italy

This matched pair of Italian red corals from The Natural Gemstone Company presents a specialist lapidary composition, each stone weighing 0.81 carats and fashioned into classic round cabochons. The measured dimensions are 6.68 by 6.76 by 2.58 mm and 6.71 by 6.70 by 2.90 mm, indicating exceptional dimensional concordance for hand-cut organic material. Both pieces exhibit an opaque body with vivid color intensity, consistent hue saturation across the dome, and an excellent polish that yields a high specular luster without surface abrasion or polish haze. As natural, untreated corals, no enhancement has been applied, preserving original cellular structure and Mediterranean provenance. The domes are proportioned to balance visual mass and mounting stability, the lower girdle radii and base planes executed to minimize light leakage and to provide predictable setting depth for bezel or cup mounts.

Pairing these cabochons required technical precision in tolerances and finishing, particularly given the slight disparity in pavilion thickness, 2.58 mm versus 2.90 mm, and microvariations in diameter that are within typical lapidary tolerance for matched sets. Successful pairing emphasizes matching not only carat weight, but also dome curvature, point of maximum height, and surface topography so that paired wearable designs maintain optical symmetry when set side by side. For craftsmen, recommended mounting strategies include custom-formed bezels with differential seat depths or stepped cups that account for the 0.32 mm thickness variance, and gentle spring-fit prongs to avoid point stresses on the coral tissue. Color matching considerations focus on metameric evaluation under daylight-equivalent lighting, ensuring the vivid red appearance remains consistent against different metal colors and under gemological lamps. These corals are particularly suitable for fine earring pairs or dual-stone rings where exacting symmetry is paramount, and where the untreated Italian origin is a valued attribute. The Natural Gemstone Company presents this pair as a ready matched set for designers who require rigorous dimensional and chromatic alignment, and who appreciate the craft required to pair organic gem material to jeweler-grade standards.
