1.64 Ct. Tourmaline from Mozambique

This specimen is a transparent, round shape brownish red tourmaline weighing 1.64 carat, with dimensions of 7.30 by 7.29 by 5.18 mm. The gem is fashioned in a mixed brilliant cut, combining brilliant style facets with proportional pavilion faceting to balance light return and color depth. Clarity has been assessed as very very slightly included at eye level, indicating that inclusions are minimal and do not affect the gem s visual appeal to the unaided eye. Color intensity is medium, yielding a warm brownish red hue that displays consistently across the table and crown facets. The surface finish is classified as excellent polish, providing crisp facet junctions and a smooth girdle for precise setting. Enhancement by heat treatment has been applied to stabilize and enrich the tone, a common and accepted practice in tourmaline to optimize color uniformity. The stone s origin is Mozambique, a source noted for producing tourmalines with attractive color and clarity characteristics.

The mixed brilliant cut in this example contributes both to scintillation and to the perception of depth, creating a versatile optical character that suits a variety of design directions. With an average diameter of approximately 7.295 mm and a depth of 5.18 mm, the stone exhibits a depth proportion of approximately 71 percent, which tends to emphasize color saturation while maintaining lively light performance. The excellent polish ensures that facet edges and the girdle will seat well in precision settings, and the very very slightly included clarity grade allows for open face mounting without the need for obscuring or extensive protective metal work. Heat treatment is stable under normal jewelry conditions, and the gem s resilience to everyday wear is typical for tourmaline when set with appropriate protection for the pavilion and girdle.

This tourmaline adapts readily to a wide range of jewelry settings. For rings, a classic four prong configuration will highlight the round silhouette and maximize visible light return, while a six prong solution increases security for daily wear. A low profile bezel setting will provide enhanced protection for the girdle and pavilion, making the gem suitable for ring designs intended for frequent use, or for pendants and bracelets where contact is more likely. A halo of accent diamonds or smaller colored stones can be used to increase perceived size and contrast, particularly in white metal for color contrast or in yellow or rose metal to harmonize with the warm brownish red tones. Cluster and three stone arrangements offer alternative aesthetics, placing the Mozambique tourmaline as either a focal center or as part of a complementary composition. The mixed brilliant cut also lends itself to precision mounting in tension style rings and modern gallery settings, provided that the setting is engineered to accommodate the gem s depth and pavilion geometry, and that a qualified jeweler assesses structural requirements for any non traditional mounting.

Customization options extend beyond setting style to include metal choice, prong profile, bezel thickness, gallery openness, and the selection of accent stones and metal finishes, each of which influences visual impact and wearability. For warm color enhancement, rose gold or yellow gold will deepen the brownish red character, whereas platinum or white gold will offer a contemporary contrast that emphasizes fire and facet brilliance. Accent diamonds in a pavé or micro pavé arrangement will increase sparkle, while colored accent stones such as small sapphires or garnets can be used to create chromatic harmony. The Natural Gemstone Company can supply detailed setting templates and collaborate with designers and manufacturers to ensure correct seat dimensions and prong placement, and to recommend protective features for applications where the piece is subject to frequent wear. Documentation of origin, treatment, and measured dimensions accompanies the gem, supporting accurate planning and confident customization for the final piece.
