3.46 Ct. Tourmaline from Mozambique

This listing presents a transparent watermelon tourmaline slice, weighing 3.46 carats. The stone measures 9.93 x 8.88 x 3.54 mm, and it retains the natural slice shape that showcases the characteristic bicolor zoning, with a pink core surrounded by a green outer zone. The cut is not applicable, as the slice preserves the crystal face and internal growth pattern rather than a conventional faceted geometry. Clarity is graded slightly included when evaluated at eye level, and the surface has an excellent polish. Color intensity is medium intense, providing a clear and attractive contrast between the central pink hue and the surrounding green, and there has been no enhancement to alter the stone, confirming that this specimen is wholly natural in appearance and treatment. The origin of this tourmaline is Mozambique, a source known for producing well colored and distinct watermelon specimens.

From a gemological perspective this slice offers a combination of transparency and visible zoning that is of interest to collectors and lapidaries. The slightly included clarity grade denotes internal characteristics that are visible to the unaided eye, and these features are part of the gemological fingerprint of natural tourmaline, contributing to identification and uniqueness rather than significantly affecting structural integrity in typical jewelry settings. The excellent polish enhances surface luster and allows the internal color zoning to be viewed with clarity. Because the slice preserves natural crystal morphology, orientation within a setting will determine how the pink and green zones present to the viewer, and careful mounting can emphasize the characteristic watermelon pattern. This specimen is ideal for collectors who value natural crystal slices, designers who seek an intact growth form for creative bezel or cameo style settings, and craftsmen interested in producing a piece that highlights natural zoning rather than faceted brilliance.

Practical considerations for use, care, and sourcing are straightforward. Tourmaline is moderately hard and can be set successfully in many types of jewelry, however care should be taken to avoid hard impact and exposure to harsh chemicals, and cleaning is best performed with warm soapy water and a soft brush, do not use ultrasonic cleaners if inclusions are present and make a jeweler aware of the slice form during any fabrication work. The lack of enhancement and the stated Mozambique origin provide clear provenance that may be important for acquisitions and resale. At The Natural Gemstone Company we document these attributes to assist accurate appraisal and design planning, and we recommend consultation with a lapidary or jeweler when incorporating a natural slice into a bespoke setting to ensure orientation and protective mounting are optimized. This watermelon tourmaline slice combines distinctive natural zoning, a transparent body, and an excellent polish, offering a well documented and visually compelling specimen for both collectors and designers.
