13.02 Ct. Coral from Australia

This listing describes a single natural orange coral specimen offered by The Natural Gemstone Company. The piece is a 13.02 carat, freeform shape coral, presented as an intricately carved floral motif. Dimensions are 18.89 x 17.95 x 6.60 mm, with a measured weight equivalent to approximately 2.60 grams. The material is opaque, displaying intense color saturation in a warm orange tone, and the surface finish is an excellent polish. The cut is not applicable in the traditional faceted sense, owing to the freeform carving, and no enhancement or treatment has been applied. The origin of this coral is Australia, and the overall presentation is consistent with hand crafted carving techniques rather than machine mass production.

From a gemological perspective, this coral is an organic gem formed of calcium carbonate, with a tactile density and polish that reflect its biological origin. The piece exhibits a waxy to silky luster when viewed under standard light, and its opacity provides a uniform color field across the carved petals. Color intensity is strong and even, with subtle natural variations that give depth to the carving. Hardness for coral is generally in the 3 to 4 range on the Mohs scale, which informs handling and setting considerations. The carving demonstrates controlled material removal and careful polishing, preserving thickness in areas of structural importance while allowing a refined floral silhouette and defined petal edges.

Practical considerations for use and care are as follows. Because coral is relatively soft and sensitive to abrasion, it is best suited to low wear jewelry applications, such as pendants, brooches, and protected ring settings where impact and friction are minimized. A bezel or halo setting that supports the perimeter and offers protection to raised elements will help preserve the carved detail. Avoid exposure to acids, household chemicals, prolonged heat, and ultrasonic cleaning, as these can damage the surface or alter the appearance. Clean with a soft cloth and mild soapy water, rinse thoroughly, and dry immediately. Store separately from harder gemstones to prevent scratching, and maintain a stable environment to avoid drying or warping over time.

This coral, sourced from Australia and presented untreated, is appropriate for collectors and designers seeking a natural, hand carved focal element with intense color and refined polish. The freeform rose carving offers a distinctive aesthetic that reads well as a central motif in bespoke pieces, and its dimensions and weight make it convenient for custom mounts. The Natural Gemstone Company can provide additional information on provenance, images from alternate angles, and handling recommendations upon request, and can assist with faceting alternatives or matched complementary stones for those considering a coordinated set. This description emphasizes the physical attributes, origin, and practical guidance necessary to evaluate the material for design and collection purposes.
