0.86 Ct. Tourmaline from Tanzania

This exquisite natural tourmaline offered by The Natural Gemstone Company is a transparent 0.86 carat oval, measuring 6.04 x 4.83 x 4.27 mm, with a mixed brilliant cut that maximizes face up brilliance and scintillation. The gem displays a warm brownish orange hue with a medium intense color saturation, and an excellent polish that enhances the surface lustre and visual appeal. No enhancements have been applied, the stone is completely natural and untreated, and the documented origin is Tanzania, a source known for producing tourmalines with appealing color and good crystal quality. For the educated buyer these objective details about weight, measurements, cut style, color intensity, polish, and enhancement status are essential, they form the basis for an informed assessment of rarity, desirability, and value.

The clarity is graded as very very slightly included evaluated at eye level, which means the gem appears clean to the unaided eye while revealing minor internal features under magnification. These inclusions can include tiny pinpoint crystals, discrete liquid or gas inclusions, and delicate growth zoning, which are common in natural tourmaline and serve as unique internal fingerprints. Rather than detracting from the gem, these inclusions authenticate its natural history, they aid future identification, and they add character that collectors and connoisseurs often value. Because the inclusions are not visually distracting at normal viewing distances, the stone maintains strong transparency and light return, allowing the color and cut to be appreciated without obvious interruptions.

The mixed brilliant cut combines a faceted crown tailored for sparkle with a pavilion designed to optimize light performance, and this geometry is particularly effective in this oval shape where length to width and proportions influence perceived size and color distribution. The dimensions and cut work together to present a lively face up appearance, and the excellent polish results in crisp facet junctions and efficient reflection of light. Tourmaline commonly exhibits pleochroism, meaning the gem can show different tones when viewed from different directions, and this brownish orange example displays subtle shifts that enrich its visual complexity. Its transparency and medium intense color intensity allow the interplay of light and color to remain balanced, without the stone appearing overly dark or washed out.

From a market and connoisseur standpoint this tourmaline represents a compelling combination of attributes, especially because it is natural and untreated, with a clarity grade that favors both eye clean appearance and evidence of natural formation. Tanzania as an origin carries a positive reputation for producing tourmalines with attractive color and stable crystal quality, which adds provenance value for discerning buyers. The 0.86 carat weight sits near the important one carat threshold, offering the option to set the gem in jewelry that benefits from a modest yet noticeable presence. The mixed brilliant cut and excellent polish enhance apparent brightness and can increase the perceived value relative to poorly cut material, while the presence of characterful inclusions supports authenticity and long term collectibility.

Care and mounting recommendations for this tourmaline focus on preserving its color and structural integrity, use warm soapy water and a soft brush for routine cleaning, avoid prolonged exposure to harsh chemicals and extreme temperature shocks, and have prongs and settings inspected periodically by a qualified jeweller. For rings consider protective settings such as bezels or lower profile prongs, and for pendants or earrings the stone benefits from designs that allow light to interact with the faceting while minimizing hard knocks. If you would like a formal appraisal, independent gemological documentation, or assistance with custom mounting options, The Natural Gemstone Company can provide guidance and trusted services to meet your needs. This brownish orange Tanzanian tourmaline is an attractive, natural, and characterful gem, well suited for the buyer seeking both beauty and the assurance of documented attributes.
