9.48 Ct. Cabochon Coral from Italy

This specimen is a single opaque marquise shaped coral cabochon, weighing 9.48 carats and measuring 9.00 by 4.00 by 2.50 millimeters, offered by The Natural Gemstone Company. The marquise outline has been executed with tight symmetry, producing balanced terminations and a consistent keel along the longitudinal axis that complements the elongated silhouette. As a cabochon, the piece displays a low, even dome that preserves the integrity of the organic structure while maximizing surface luster. The color palette is a delicate interplay of salmon and creamy white, with an overall medium light color intensity. Salmon hues present as soft, warm salmon washes that gently grade into the white ground, rather than as stark banding, yielding an understated, even appearance suitable for classic and contemporary settings. The material is correctly described as opaque, with a waxy to softly silky surface sheen that reads as excellent polish under standard magnification. No faceting is present, instead the cutter focused on achieving precise contouring, even apex height across the dome, and a narrow, polished edge to allow for secure bezel seating without compromising the marquise termination points.

From a lapidary and gemological perspective this coral demonstrates careful craftsmanship. The cutter maintained proportional thickness along the 9.00 millimeter length, leaving sufficient depth at the 2.50 millimeter profile to ensure mechanical stability for bezel or inlay mounting while keeping the cabochon visually elegant and lightweight. The polish stage shows attention to final surface integrity, removing micro-scratches and producing a uniform reflectivity across both the salmon flushes and white areas, which is critical for organic materials where surface defects are easily visible. There are no indications of dyeing, stabilization, or filling, and the piece is untreated, consistent with the enhancement report of no enhancement. Origin from Italy places the material within the Mediterranean sourcing context, which is historically significant for desirably hued corals and contributes to provenance-based valuation. The natural color transition and absence of artificial saturation or surface coatings were preserved during cutting, highlighting the material’s native tonal qualities.

Technically relevant physical properties should be considered by designers and end users. Coral is an organogenic gem primarily composed of calcium carbonate in the aragonite form, with an expected specific gravity in the range typical for natural coral, and Mohs hardness approximately 3.5 to 4.0. These properties dictate gentle handling and protective mounting choices. Because the cabochon is shallow and elongated, bezel settings are particularly recommended to protect the marquise points from impact and to distribute mechanical stress along the edge. Inlay applications and pendants where the stone is less exposed to abrasion are excellent uses, while ring settings can be achieved provided the design incorporates reinforced bezels or protective shoulders. Avoid ultrasonic cleaners, steam cleaning, and harsh chemicals, as the calcium carbonate matrix is susceptible to acids, prolonged heat, and solvent exposure. Cleaning with a soft cloth and a mild aqueous detergent, followed by immediate drying, preserves polish and color. Routine care also includes minimizing contact with perfumes, hair products, and chlorinated water to maintain surface integrity.

For buyers and designers assessing this piece, the combination of measured dimensions, 9.48 carat weight, marquise geometry, cabochon cut with excellent polish, medium light salmon and white coloration, lack of treatments, and Italian origin creates a clearly defined specification useful for appraisal and design planning. The Natural Gemstone Company documents these technical attributes to facilitate informed purchasing and to support accurate integration into bespoke settings. Given the material’s organogenic nature, the documented absence of enhancements and the precise lapidary work are primary value determinants, alongside provenance and color quality. This marquise coral cabochon is therefore well suited for collectors and craftsmen who prioritize native color fidelity, artisanal cutting consistency, and responsible sourcing in Mediterranean corals.
