4.18 Ct. Tourmaline from Nigeria

This transparent Other certified purplish pink tourmaline weighs 4.18 carats, presenting as a heart shape with dimensions of 11.08 x 12.48 x 5.03 mm, originating from Nigeria, and certified with no enhancement. The pavilion and crown have been executed in a mixed brilliant cut, combining triangular and kite shaped brilliant facets on the crown with a subtly faceted pavilion to optimize return of light, and the overall finish is described as excellent polish. The body color registers as brownish red with strong purplish pink overtone, and the color intensity is reported as intense, producing a rich, saturated face up appearance. Clarity is graded as very slightly included when evaluated at eye level, with minute inclusions that do not interrupt transparency or light transmission, preserving the gem s scintillation and visual appeal for close inspection and daily wear.

From a cutting and proportion perspective this stone exhibits a broad face up spread relative to its weight, a direct consequence of the heart shape outline and the chosen cutting style. The depth, at 5.03 mm on a 11.08 x 12.48 mm plan, yields an approximate depth ratio of 42.7 percent based on the length and width average, which indicates a relatively shallow profile suited to maximizing apparent size when set. The mixed brilliant faceting pattern enhances contrast and scintillation across the lobes and cleft, while maintaining strong central brilliance thanks to a well managed table facet and precise facet junctions. Symmetry of the heart lobes is critical, and this specimen demonstrates balanced lobes with a clean cleft, allowing the final setting designer to maintain the iconic heart silhouette without additional re-cutting or compromise to gem weight.

For custom jewelry design this tourmaline is exceptionally well suited to function as a dramatic center stone, its 4.18 carat weight and broad face up dimensions creating a commanding presence in rings, pendants, and solitaire pendants. For ring settings a secure V style prong at the tip and three to four well positioned prongs across the lobes ensure protection of the delicate points while preserving maximum light entry, or alternatively a low profile bezel with a relief edge can offer full protection while showcasing the mixed brilliant faceting. The shallow depth and wide spread favor halo designs and pavé shoulders, as accent diamonds or colored melee will sit close to the gallery without creating excessive height, and the strong color presence allows for creative contrast with white diamonds, or warm metal pairings in 18 karat yellow or rose gold to intensify the brownish red and purplish pink nuances. For pendant work the heart outline lends itself to open bail designs or flush mount bezels, and matched pairs for drop earrings can be achieved by working with our cutter to select complementary stones or by reorienting the mounting to balance weight distribution.

At The Natural Gemstone Company we provide full condition disclosure, certification details, and high resolution imagery to support the design process, and we can supply additional documentation upon request to confirm the no enhancement treatment status and Nigerian origin. Our bench and design advisors recommend confirming prong gauge and gallery clearance in CAD mockups prior to fabrication, given the shallow depth and broad spread, and we can advise on specific girdle handling and secure setting profiles to maximize longevity without sacrificing face up brilliance. If you prefer escorted design development we offer mounting templates and live evaluations with professional setters experienced in heart shapes and mixed brilliant tourmalines, ensuring the final commission preserves the stone s intense color, excellent polish, and natural clarity, while achieving the practical protections required for everyday wear.
