3.71 Ct. Cabochon Coral from Italy

This listing describes one naturally formed, opaque orange coral, precision measured at 3.71 carats, oval shape, measuring 12.18 by 9.67 by 4.22 mm, and finished as a cabochon. The dome is smooth and symmetrical, with an excellent polish that produces a soft, satiny luster across the surface. Color intensity is vivid, presenting a warm orange tone that is uniform across the face of the stone, with subtle natural growth lines visible under magnification that attest to its organic origin. No enhancement has been applied to this specimen, and the stated origin is Italy, a region historically recognized for Mediterranean coral. The Natural Gemstone Company documents the gem as untreated, and the combination of weight, shape, and finish makes this coral a representative example of quality organic gemstone material.

From a material properties perspective, this coral should be considered an organic gem with moderate durability. Coral typically registers around 3.0 to 4.0 on the Mohs scale and a specific gravity near 2.6, which informs handling and setting considerations. The cabochon cut and the relatively low dome height to diameter ratio in this piece provide a stable profile that works well in protective settings. Practical mounting recommendations include bezel settings, closed back settings, and designs where the stone is held within a frame to reduce exposure to incidental abrasion or impact. For jewelry intended for frequent wear such as rings, plan for protective design features, while pendants and earrings are appropriate choices when less direct abrasion is anticipated.

Care and long term preservation require attention to common sensitivities of coral. Avoid exposure to household chemicals, acids, cosmetics, perfumes, and prolonged contact with hot water, as these can alter surface sheen and color over time. Ultrasonic cleaners and steam cleaning are not recommended for coral, due to potential for internal stress or surface alteration. Cleaning can be accomplished with a soft, damp cloth and mild soap if needed, followed by thorough drying. The untreated origin from Italy is significant to collectors and designers, as natural color and lack of enhancement are primary factors in evaluating coral, together with surface condition and uniformity. The Natural Gemstone Company can assist with additional details upon request, including viewing images under different lighting conditions and discussion of setting options that preserve both the aesthetic qualities and the structural integrity of this coral.
