1.58 Ct. Tourmaline from Africa

This transparent 1.58 carat bi color tourmaline measures 10.76 x 5.20 x 3.19 mm and is fashioned in an emerald cut that emphasizes linear symmetry and internal depth, a profile that suits both classic and contemporary jewelry designs. The gem exhibits a well defined bi color transition, with warm pink tones graduating to complementary golden and subtle greenish hues, and displays a medium intense color saturation that reads evenly across the length of the stone. Clarity is graded as very slightly included when examined at eye level, which conveys a high degree of visual purity while retaining natural internal character that confirms the stone is natural and untreated. The polish is excellent, with crisp facet junctions and reflective step facets that contribute to an elegant face up appearance and controlled light return. There has been no enhancement applied to this tourmaline, a characteristic that preserves both its original optical properties and its market standing among collectors and discerning setters.

The origin of this tourmaline in Africa underpins several of its most important attributes, and informs both its aesthetic and market value. African pegmatitic environments are distinguished by complex cooling histories and variable trace element chemistries, conditions that commonly yield tourmalines with pronounced color zoning and bi chromatic effects, features that are prized for their natural artistry and geological provenance. The fact that this stone is naturally bi color and untreated increases its rarity relative to heat treated or otherwise enhanced material, and collectors typically assign additional worth to gemstones that retain unaltered optical features that directly reflect their formation environment. Provenance from Africa also connects the gemstone to a long history of gem quality tourmaline production, and for many buyers the documented origin provides confidence in the material description and a meaningful narrative about the gem s geological journey from pegmatite to finished facet.

From a design and practical perspective, the emerald cut and the stone s dimensions make it particularly suitable for architectural settings that accentuate its step facets and color transition. The elongated 10.76 x 5.20 mm outline balances presence with wearability, allowing the piece to sit comfortably in a ring or to be oriented vertically or horizontally in a pendant, where the bi color effect can be showcased as a linear gradient. The very slightly included clarity grade supports clean visibility through the pavilion and table, and the excellent polish ensures smooth facet planes that aid in secure mounting and reduce the likelihood of surface abrasion. When designing around this tourmaline, gold alloys and clean bezel or four prong settings will preserve the stone s silhouette and protect its corners, while open gallery work will allow light to interact with the color zones for maximum visual impact. For care, the gem should be cleaned with mild soap and warm water and a soft brush, and routine inspection by a professional jeweler is recommended to monitor the integrity of any setting given the stone s natural inclusions.
