2.48 Ct. Bi Color Tourmaline from Mozambique

This exceptional bi color tourmaline is a refined choice for the collector who values both rarity and classical elegance. Weighing 2.48 carats and cut in a precise emerald shape, this stone measures 11.73 x 6.01 x 4.19 mm, dimensions that lend it a commanding presence while remaining perfectly proportioned for bespoke rings and sophisticated pendant designs. The gem is transparent with a medium color intensity that allows the bi color character to present clearly under natural and gallery lighting, showing a pleasing transition between rose pink tones and a deeper, slightly more saturated inner zone. The elongated emerald cut and faceted step pattern create long, mirrored facets that emphasize the color zoning and the stones natural clarity, delivering a restrained brilliance that is especially prized by connoisseurs who prefer refined light performance over excessive scintillation.

From a clarity and finish perspective this tourmaline is exceptional. It has been graded as very very slightly included when evaluated at eye level, which for educated buyers means the gem is effectively eye clean to most observers, with only minute and unobtrusive inclusions visible under close inspection. These minimal inclusions do not compromise the gemfs durability or its ability to transmit light freely, they instead authenticate the natural origin and add to the gemfs individuality. The polish is rated excellent, indicating crisp facet junctions, smooth facet planes, and an overall surface quality that maximizes both luster and the legibility of the stones internal color distribution. The proportions of length, width, and depth yield an approximate depth of 4.19 mm relative to the width, which is a balanced proportion for an emerald cut, enabling optimal color saturation while preserving a pleasing profile in settings.

Geologically and commercially this piece carries compelling provenance. Originating from Mozambique, a region recognized for producing some of the worlds finest pink and bicolored tourmalines, this stone benefits from pegmatitic sources that yield saturated yet transparent material. The current market places a premium on stones with verifiable origin and attractive natural color combinations, and Mozambican tourmalines have established a strong reputation among gemmologists and collectors alike. The gem has undergone heat treatment, a widely accepted and stable enhancement in tourmaline that can improve color uniformity and reduce undesired brownish overtones without affecting the stones structural integrity. This treatment is routine for the trade, it is permanent, and it is fully disclosed, which preserves the itemfs marketability and conforms to ethical selling practices.
