1.79 Ct. Green Tourmaline from Brazil

This beautiful transparent 1.79 carat pear shape green tourmaline from Brazil presents a compelling combination of gemological quality and visual appeal, qualities that The Natural Gemstone Company is proud to offer. The stone measures 9.05 x 7.01 x 4.60 mm and is faceted in a mixed brilliant cut, a cutting style that blends a brilliant facet arrangement in the crown with step or pavilion elements to maximize both sparkle and color saturation. The clarity is graded as slightly included when evaluated at eye level, meaning minor natural inclusions are present but do not distract from the gem's overall appearance or brilliance. The color intensity is described as intense, which in green tourmalines translates to a rich, vivid green that reads strongly face up and benefits from the pear silhouette for an elegant, elongated presentation. The polish has been evaluated as excellent, indicating precise facet finishing and surface smoothness that enhance light performance and tactile quality. The stone has been heat treated, a standard and stable enhancement in tourmalines that improves color uniformity, and the origin is Brazil, a historically important and respected source for fine green tourmalines.

From a technical grading perspective this tourmaline checks many boxes that educated buyers consider when assessing value. The 1.79 carat weight places the stone well above common commercial sizes, and combined with its intense color and excellent polish it achieves a premium position on the price curve for green tourmaline. The mixed brilliant cut is advantageous for a pear shape, because it balances scintillation with color depth. The dimensions of 9.05 x 7.01 x 4.60 mm give the gem a pleasing face up size and a depth that supports strong light return and vivid color presentation without appearing too deep or shallow in a standard setting. Slightly included clarity at eye level means the stone is not eye clean under close inspection, however the inclusions are minor and natural, they confirm the gem is natural and not synthetic, and in many cases they are positioned so as to not interfere with the visual impression. Heat treatment in tourmaline is widely accepted within the trade when fully disclosed, because it is stable and does not diminish the structural integrity of the material. Transparent disclosure of origin and treatment, as provided by The Natural Gemstone Company, is essential for trust and accurate valuation.

As an investment proposition this green tourmaline offers attributes that can support future appreciation. Demand for colored gemstones has been growing among collectors and investors who seek portfolio diversification beyond traditional assets, and green tourmaline benefits from a steady collector interest due to its range of desirable greens, relative rarity in top saturations compared with more common tones, and the historical significance of Brazilian sources. Fine examples with intense color, good size, and attractive cuts tend to outperform lower quality material over time, especially when accompanied by reliable provenance and treatment disclosure. Market dynamics that favor appreciation include constrained supply from primary sources, periodic mine closures or reduced output, and rising interest among jewelry designers and private collectors in unique colored gemstones. The presence of slight inclusions reduces the absolute top market tier, yet the balance of weight, intense color, excellent polish, and classic pear shape positions this stone to capture both collector and jewelry markets. For investors who prioritize liquidity and resale value, securing a professional laboratory report, maintaining documentation of origin and treatment, and buying from reputable houses such as The Natural Gemstone Company enhance marketability and preserve value over time.

Beyond investment considerations this tourmaline is also an excellent candidate for a signature jewelry piece, combining wearability with lasting beauty. Tourmaline has a Mohs hardness around 7 to 7.5, which makes it suitable for rings and pendants when set with reasonable care, and the pear shape offers elegant design possibilities that accentuate the gem's color and sparkle. The mixed brilliant cut and excellent polish will deliver lively scintillation in a halo or solitaire mounting, and the dimensions make the gem a comfortable size for daily wear or occasional showcase pieces. Care recommendations include avoiding harsh knocks, storing separately to prevent abrasion, and cleaning with warm soapy water or a gentle ultrasonic if no surface-reaching fractures are present. The Natural Gemstone Company stands behind this gem with full disclosure of its characteristics, and we recommend that discerning buyers request a certificate from a recognized gemological laboratory if they intend to treat the purchase as an investment. With documented provenance, transparent treatment disclosure, and the intrinsic qualities of weight, color, and cut, this 1.79 carat pear shape green tourmaline represents a thoughtful acquisition for both connoisseurs seeking aesthetic satisfaction and investors seeking potential appreciation.
