1.62 Ct. Salmon (Orange) Cabochon Coral from Italy

This offering from The Natural Gemstone Company is a precisely fashioned marquise cabochon coral weighing 1.62 carats, with exact dimensions of 11.85 x 5.76 x 3.53 mm. The marquise outline is executed with a clear emphasis on symmetry, yielding an elongated classic profile with a length to width ratio just over two to one, which translates into an elegant finger presence when set. The cabochon cut features a smooth domed crown and a carefully reduced pavilion thickness, dimensions selected to balance visual depth with structural integrity. The 3.53 mm height provides a moderate dome that preserves the stone volume and allows the salmon color to present uniformly across the surface, while the marquise terminations are precisely tapered to avoid thin vulnerable points. Weight distribution is consistent with the stated specific gravity typical of natural coral materials, and the stone sits well within the expected tolerances for lapidary yield on a piece of this size and shape.

Color evaluation for this coral emphasizes hue, tone, and saturation, with the dominant hue described as salmon, a warm orange blend with subtle pink undertones that shift slightly under different light sources. Intensity is classified as vivid, indicating a high saturation level with minimal dilution by gray or brown tones, and overall tone falls into the medium range where the color reads strongly without loss of surface reflection. The specimen is opaque, which in coral is a desirable attribute because it yields a uniform color field free from internal reflections that can distract from the pure body color. The polish on this cabochon is excellent, imparting a soft waxy luster that is characteristic of high quality coral, and the absence of enhancements confirms that the color and surface finish are natural and the result of expert cutting and polishing rather than dyeing or bleaching. Origin is recorded as Italy, reflecting Mediterranean provenance and traditional sourcing, which is an important factor for collectors and connoisseurs who value geographical specificity in organic gem materials.

From a lapidary perspective, the piece demonstrates meticulous craftsmanship across preform, shaping, and finishing stages. The marquise preform was established to maintain equal curvature along the central axis, a necessary step to ensure even light absorption and visual balance in opaque cabochons. Grinding was performed with progressively finer abrasives to establish the dome geometry and to remove stress risers that can occur when forming pointed terminations. The finishing sequence includes multiple stages of silicon carbide and aluminium oxide sanding to refine the surface microtopography, followed by a final polish using cerium oxide or a fine diamond lacquer depending on the lapidary shop preference, producing the mirror like sheen visible in the photographs. Edge work shows a subtly rounded girdle appropriate for bezel mounting, providing mechanical support while avoiding excessive bulk at the rim. The lack of surface pits, cleavage lines, or porosity suggests the cutter selected a clean section of the original material and oriented the piece to minimize inclusions and natural flaws, a consideration that directly impacts both durability and aesthetic value.

Practical considerations for designers and end users include setting recommendations, wear considerations, and long term care. Given coral hardness in the low to mid Mohs range, care should be taken to protect the marquise points, and a bezel setting is recommended for daily wear pieces because it supports the edges and reduces the chance of impact damage. When designers choose metal, warm tones such as 18 carat yellow gold enhance the salmon orange warmth, while platinum or white gold produces a modern contrast that emphasizes shape over color. Because this coral is confirmed unenhanced, its color stability is intrinsically sound, however it remains an organic material and should be protected from prolonged exposure to strong heat, household chemicals, and ultrasonic or steam cleaning processes. Cleaning with a soft cloth and mild soap and water is sufficient, followed by careful drying and storage away from hard gemstones that could abrade the polish. For collectors seeking certification, The Natural Gemstone Company can assist with detailed documentation of weight, dimensions, origin, and enhancement status, and can provide guidance for bespoke mounting options that preserve the integrity and showcase the vivid salmon tone of this attractive marquise cabochon.
