2.27 Ct. Pink Tourmaline from Brazil

This specimen from The Natural Gemstone Company is a transparent pink tourmaline weighing 2.27 carats, cut into a classic cushion outline with dimensions 8.37 x 7.64 x 5.13 mm. The cutter selected a mixed brilliant faceting scheme to balance maximum internal brilliance with an even colour distribution. Clarity is graded very slightly included when evaluated at eye level, which means that at normal viewing distances the stone reads clean and offers uninterrupted visual depth. The colour intensity is described as intense, yielding saturated pink tones that remain lively even under variable lighting conditions. The gem has received an excellent polish, producing crisp facet junctions and strong facet reflections. The material has been heat treated, a stable and accepted enhancement that subtly modifies tone and saturation, and the provenance is Brazil, a source known for well crystallized tourmaline material with attractive hue range.

From a cutting and optical engineering viewpoint the mixed brilliant configuration on this cushion is purposeful. The crown employs a series of kite shaped and star facets above a moderately sized table to preserve the saturated body colour, while the pavilion mixes triangular and kite facets to return light efficiently without excessive windowing. The result is a balance of lively scintillation and steady colour field, a desirable quality in pink tourmaline where excessive brilliance can dilute perceived saturation. Facet angles were optimized to the refractive index range of tourmaline, and the girdle profile is thin to slightly thick to permit secure setting without compromising light return. The pavilion depth at 5.13 mm was negotiated to avoid a dark culet effect, and the excellent polish supports crisp, mirror like facet faces that increase contrast and sparkle. The mixed cut also mitigates some degree of pleochroism by orienting the stone so that primary viewing angles present the most attractive hue.

Inclusions are present at a level that is very slightly included to the unaided eye, and this grading indicates that inclusions do not materially affect either aesthetic performance or structural integrity under normal wear. Typical internal features in Brazilian tourmaline include fine needle like inclusions and fluid cavities, elements that can interact with light to add depth rather than distract. For practical jewellery engineering, tourmaline has a Mohs hardness in the mid sevens and a perfect or distinct cleavage, so careful setting design is important. Recommended mounting practices include four or six prong seats with gentle rounded prong interiors to cradle the cushion girdle, or a thin bezel that protects the edges while allowing light ingress through the crown. When the piece is intended for everyday wear, a lower bezel or partial bezel collar can shield vulnerable girdle facets without deadening the stone. All finishing work should preserve the excellent polish, with minimal post setting reworking that could induce surface abrasion.

For custom designs where this pink tourmaline is the focal stone there are several complementary approaches that leverage its intense colour and mixed brilliant cut. For contrast that heightens chroma choose small round brilliant white diamonds in a halo and on the shoulders, their high dispersion and white body colour will increase apparent saturation of the pink field. For a vivid complementary palette select small tsavorite garnets or chrome diopside green accents, their saturated green will create a high contrast colour play that reads contemporary and energetic. For a more tonal and soft composition use morganite or light pink sapphire accents to create graduated warmth, and rose gold metalwork will sympathetically enhance the pink tones while yellow gold will provide a vintage inspired warmth. Platinum or white gold settings emphasize the gemstone alone with cool contrast and suit designs that use brilliant cut diamond accents. Design motifs can include a single row halo of melee diamonds to amplify brilliance, tapered baguettes to elongate the finger plane in a ring, or delicate pavé shoulders that feed light into the pavilion. With dimensions of 8.37 x 7.64 x 5.13 mm the stone sits well in standard custom seats micromeasured to the millimetre, and The Natural Gemstone Company can advise on prong thickness and bezel lip proportions to ensure secure fitting and optimal light performance.
