28.64 Ct. Green Star Tourmaline from Mozambique

At The Natural Gemstone Company we are pleased to present a truly singular treasure, a one of a kind green star tourmaline that speaks to collectors and connoisseurs who seek rarity and refinement. This translucent oval cabochon weighs 28.64 carat, and measures 19.50 by 16.80 by 10.70 mm, proportions that are rare for a gem of this nature and size. Originating from Mozambique, this piece is untouched by enhancement, offering a pure, natural statement of color and optical wonder. Owning this tourmaline is an invitation to join an exclusive circle of patrons who understand that the finest gems are not merely worn, they are stewarded and admired across generations.

Visually, this green star tourmaline commands attention with its intense color intensity and a finely centered asterism that comes to life under a direct light source. The cabochon cut has been expertly executed to showcase the star, and the excellent polish delivers a deep, satiny surface that enhances the gem’s depth and liveliness. At eye level the clarity is graded as very slightly included, a testament to the stone’s natural origin and to the expert cutting that minimizes distraction while preserving character. The translucence allows the star to hover within the gem, a luminous thread of light that moves gently as the stone is rotated, offering a private performance that only the owner can fully appreciate.

Beyond its immediate beauty, this Mozambique star tourmaline carries the rarity inherent to larger, well formed star tourmalines, especially in a green hue with such saturation. Tourmaline mines in Mozambique are known for producing exceptional material, yet specimens of this scale, with undisturbed asterism and without enhancement, are found only intermittently. For the collector who values provenance and natural integrity, this gem represents a scarce opportunity. It is ideal for museum quality mounts, bespoke jewelry commissions, or as a centerpiece in a collection that speaks of discerning taste and a commitment to owning gems that are as honest and unaltered as possible.

As stewards of rare natural gemstones, The Natural Gemstone Company offers this green star tourmaline with full support for certification and bespoke setting services. We recommend a design that embraces the cabochon shape and allows light to interact with the stone, such as a halo or bezel that frames the oval without obscuring the star, or a custom pendant that offers movement to reveal the asterism. Each inquiry will be handled privately, and we are pleased to arrange viewing, detailed imagery, and independent gemological reports upon request. For collectors who seek exclusivity, this single piece is available now, and we invite serious inquiries to speak directly with our gem specialists to ensure this unique gem finds its rightful place in a collection where it will be treasured for generations.
