3.39 Ct. Bluish Green Paraiba Tourmaline from Africa

This 3.39 carat oval bluish green paraiba tourmaline represents a technically refined specimen, well suited for a high end gemstone collection. The stone measures 12.40 x 7.73 x 4.95 mm, yielding a length to width ratio of approximately 1.60, which produces a visually elegant elongation without sacrificing face up balance. The cutting style is faceted with a mixed brilliant design, and the proportions give a measured depth to average diameter ratio of approximately 49.2 percent, a deliberate choice by the cutter to optimize face up spread and apparent size. Clarity is graded Included at eye level, light color intensity is present, and the surface finish is an excellent polish. The piece is entirely natural with no enhancement, and its origin is Africa, attributes that enhance its desirability among connoisseurs who prioritize provenance and untreated material. The Natural Gemstone Company offers this stone as a ready to integrate centerpiece for a curated collection or as the foundation for a bespoke high end setting.

From a lapidary perspective the mixed brilliant faceting is executed to harmonize scintillation and color transmission. The crown employs brilliant style facets to create lively facet to facet contrast and dynamic white light return, while the pavilion integrates step influenced planes with brilliant pavilion facets to guide colored light back through the table. This hybrid approach increases apparent brightness, and in a copper bearing tourmaline it also influences the distribution of the bluish green hue across the table and shoulders. The cutter prioritized precise facet junctions and planar integrity to achieve an excellent polish, which minimizes light leakage and permits the copper induced hue to remain vivid even at a light intensity grade. The oval outline and the chosen length to width ratio emphasize dispersion along the table, providing a pleasing play between broad flash and pinpoint scintillation, characteristics that appeal to technically minded collectors evaluating optical performance as well as color.

The included clarity grade reflects internal features visible at typical viewing distance, consistent with natural tourmaline crystallography, and these features do not significantly compromise light performance due to the optimized facet architecture. Typical internal characteristics in African paraiba tourmaline, such as fine growth features or minute needle like inclusions, can be present, and in this piece they contribute to the gemological fingerprint without detracting from overall beauty. The light color intensity places this specimen in a category where copper induced bluish green tones are present and perceptible, yet the hue reads differently under varied lighting, offering collectors a nuanced color experience rather than a single static appearance. As an untreated African paraiba of 3.39 carats, this tourmaline occupies a rare quadrant in the market where size, natural color, and lapidary quality intersect, making it an excellent acquisition for investment grade cabinets or museum level display. For bespoke jewelry settings the gem will benefit from open prong mounting or a low bezel that maximizes light access and face up color, and care recommendations include avoiding prolonged exposure to strong heat or harsh chemicals to preserve the untreated color. This paraiba tourmaline is presented by The Natural Gemstone Company as a technically accomplished, collectible specimen, ideal for a discerning buyer seeking a high end addition that combines measured proportions, refined faceting, natural copper influenced color, and meticulous polish.
