2.06 Ct. Tanzanite from Tanzania

This specimen is a transparent 2.06 carat blue tanzanite presented in an emerald cut, with exact dimensions of 9.04 x 7.01 x 3.57 mm. The emerald cut configuration employs a series of step facets on the crown and pavilion, producing elongated rectangular facets that run parallel to the girdle, and a broad open table that emphasizes both color and clarity. The length to width ratio is 1.29 to 1, an elegant proportion that preserves the classic rectangular silhouette while maximizing face up surface area. The clarity has been evaluated at eye level as very very slightly included, a grade that allows the stone to present a clean visual field in typical jewelry settings. The polish is excellent, indicating a high degree of lapidary finish where facet junctions are crisp and facet planes are free from visible abrasion or polish haze. The piece is heat treated to develop and stabilize the intense blue hue, an industry standard enhancement, and the origin is Tanzania, a provenance that is synonymous with tanzanite of the highest saturation and character. The Natural Gemstone Company presents this gem as a ready to mount center stone for clients who require technical excellence and aesthetic presence.

The intense color intensity of this tanzanite is its most striking attribute, and the emerald cut magnifies that attribute by presenting a large table facet that delivers uniform color across the face of the stone. Tanzanite is strongly pleochroic, exhibiting different color directions when viewed along different crystallographic axes, and high quality material will show dominant strong blue tones with secondary violet or blue violet flashes depending on orientation and lighting. In this specimen the predominant face up color is an intense saturated blue, with subtle violet undertones when tilted, a behavior that is fully compatible with expert expectations for heated tanzanite from Tanzanian deposits. The step cut faceting scheme reduces the scintillation typical of brilliant cuts, trading that effect for broad flashes of color and polished planes that draw the eye to chromatic depth. For connoisseurs who prioritize color purity and saturation, this approach reveals the gem in a way that is often more compelling than complex brilliant facet arrangements, because the treatment of light emphasizes hue and saturation rather than fire and sparkle.

From a clarity and durability perspective this 2.06 carat emerald cut tanzanite performs excellently, the very very slightly included grade at eye level indicating that inclusions are minimal and generally not disruptive under normal wear. Emerald cut geometries tend to act as a magnifier for internal features due to the large table, yet this stone maintains a clean presentation, suggesting precise orientation and selective removal of inclusions during preform and final cutting. The excellent polish contributes to strong surface luster and optimal light transmission, and facet symmetry has been executed to tight tolerances, ensuring consistent facet alignment and even reflections across the crown. Tanzanite has a Mohs hardness that is moderate, which recommends protective mounting strategies for everyday wear, particularly for ring designs. We advise settings that secure the corners and girdle, such as four prong or bezel environments with minimal exposure of the girdle, while maintaining the open table required to show the stone s color. Because the material is pleochroic, final orientation in the mounting will influence the dominant face up color, and our cutters at The Natural Gemstone Company can advise on orientation to achieve the desired appearance in a chosen setting.

The craftsmanship behind this stone reflects deliberate choices by experienced lapidaries, starting with heat treatment to remove brown and earthy tones and to enhance the strong blue saturation that is prized in the market, continuing through precise cutting that preserves weight while optimizing color presentation. Heat treatment in tanzanite is a stable enhancement when properly applied, and it is disclosed here in keeping with full transparency. The step cut execution shows careful facet planning, with crown and pavilion steps balanced to avoid dark corners and to create a uniform color field, while the table size and depth relationship have been tuned to the material to produce an attractive face up presence. Sourcing from Tanzania provides a geological context that aligns with the gem s character, and at The Natural Gemstone Company we pair provenance disclosure with technical documentation and high resolution imagery so that buyers can assess cut, color, and clarity with confidence. For settings, white metals such as platinum or white gold tend to emphasize the cool intense blue, whereas warmer metals will shift perception toward violet, a characteristic that can be used as a design tool. For care, we recommend gentle cleaning with lukewarm soapy water and a soft brush, avoiding sudden thermal shock and aggressive ultrasonic treatment without prior assessment, to preserve the stone s integrity and polish. This emerald cut blue tanzanite is a technical specimen that will stand out in any jewelry setting, offering compelling color saturation, precise faceting, and provenance backed by The Natural Gemstone Company.
