13.51 Ct. Green Tourmaline from Mozambique

This exquisite green tourmaline is a remarkable example of natural beauty and lapidary skill, weighing 13.51 carats, and shaped into a classic pear shape with precise dimensions of 19.90 x 11.60 x 9.40 mm, faceted and finished in a mixed brilliant cut. The combination of size and cut produces an impressive presence, offering both length and breadth that make it suitable for a bold solitaire ring, a statement pendant, or a centerpiece in a bespoke high end necklace. The gem displays intense color intensity, with saturated green tones that remain vivid across the table and down the pavilion, and an excellent polish that translates into lively brilliance and scintillation. Clarity is graded as very very slightly included evaluated at eye level, meaning the stone reads eye clean to most observers while retaining internal characteristics that are natural and consistent with untreated rough. The stone has undergone a standard and stable enhancement, heat treated, which is fully disclosed, and the material originates from Mozambique, a region known for producing richly colored tourmalines that combine excellent color with desirable clarity.

From a technical grading perspective the elements that determine the attractiveness and value of this specimen are its color, clarity, cut, carat weight, and origin. Color is the single most important parameter for green tourmaline, and this gem exhibits intense saturation that appeals to connoisseurs who prioritize depth and evenness of hue. The clarity grade of very very slightly included evaluated at eye level indicates that inclusions are minimal and do not detract from face up beauty, which is especially notable in a stone of this scale. The mixed brilliant cut is a deliberate lapidary choice to maximize light return while maintaining a pleasing outline and weight retention. A mixed brilliant combines crown facets that promote scintillation with pavilion facet geometry that enhances depth and fire, creating a dynamic visual performance under a variety of lighting conditions. The excellent polish further supports crisp facet junctions and smooth surfaces, ensuring optimal luster. Heat treatment is a well established and widely accepted enhancement for tourmaline, employed to refine color while maintaining stability and durability. Full disclosure of this treatment is provided, and educated buyers understand that heat treated gemstones trade transparently in the market as long as the treatment is stable and permanent.

For the educated buyer this 13.51 carat pear shape green tourmaline represents both an aesthetic acquisition and a considered investment in craftsmanship. Large, eye clean, and intensely colored tourmalines of this quality are less common than smaller or heavily included examples, which confers rarity value to stones with these combined attributes. The Mozambique origin adds provenance value, as the region produces tourmalines with rich, saturated hues that command attention from collectors and designers alike. When set by a skilled jeweler, the mixed brilliant cut responds beautifully to precision settings that showcase the stone without obscuring its profile. The pear shape offers versatility in design, allowing creative placement to elongate the finger in a ring or to create movement in a pendant. From a practical standpoint tourmaline has a Mohs hardness seven to seven and a half, which means it is robust enough for everyday wear when set with appropriate protective measures, yet it benefits from careful handling and periodic professional cleaning to preserve its finish. An educated buyer will appreciate that acquiring a gemstone of this caliber is an investment in a tangible, enduring asset that combines natural rarity with expert cutting and finishing.
