2.79 Ct. Tourmaline from Mozambique

One transparent watermelon tourmaline slice, weight 2.79 carats, dimensions 9.70 x 9.98 x 2.85 mm, slice shape, cut not applicable. The gem is a natural specimen originating from Mozambique. The exterior form reflects a cross section from a tabular crystal, presenting a circular to slightly angular outline typical of slices removed from prismatic tourmaline. Measurements are provided to the nearest hundredth of a millimeter, and the weight is recorded in carats for precision. The polish on the exposed faces is excellent, producing a clean, smooth surface that enhances the interaction of light with the internal color zones. No enhancements were applied to this material, the stone is offered in its natural state with features and character resulting from its original formation.

Coloration is the defining attribute of this specimen, exhibiting the classic watermelon effect, with a distinctly pink core enclosed by a surrounding green rim. Color intensity is described as medium intense, which communicates a pleasing saturation without appearing overly dark or muted. The transition between pink and green is clearly defined, and the internal zoning displays a natural concentrically banded pattern typical of bi color and multicolor tourmalines. Under standard viewing conditions the pink central zone presents as a warm, slightly cool pink depending on orientation, while the green outer zone ranges from a fresh mint to a slightly deeper green near the perimeter. These color relationships contribute to visual contrast and interest when the slice is viewed face up or when set in an open back mounting.

Clarity is graded as included, evaluated at eye level, which indicates that there are visible natural inclusions that can be seen without magnification. The internal features include growth related structures and internal boundaries that are characteristic of tourmaline crystallization. These inclusions do not detract from the overall aesthetic, rather they confirm the natural origin and add to the specimen character. The central pink area displays some internal texture that is visible through the transparent material, and the green rim contains subtle internal features consistent with natural growth zoning. The excellent polish applied to the flat surfaces minimizes surface interference and allows the inclusions and color zones to be observed with clarity. The slice form means that edge continuity may be irregular, and the outer rim retains some of the original crystal habit, which can be incorporated into design or further refined by a cutter.

No treatments or enhancements are reported for this watermelon tourmaline, the stone is untreated and natural. Origin is Mozambique, a source known for producing fine tourmaline varieties with vivid color zoning. For practical considerations, tourmaline has a Mohs hardness in the range of 7 to 7.5, which supports use in many jewelry applications, though the slice shape and visible included areas suggest settings that protect exposed edges are preferable. Recommended mounting styles include bezel settings, custom open back frames, or pendants which allow the natural slice aspect to be showcased while minimizing mechanical risk to the perimeter. If repolishing or reshaping is desired to refine the outline or to prepare the piece for a specific setting, the existing excellent polish and structural form will allow a lapidary to evaluate retention of weight versus desired finished shape.
