16.10 Ct. Green Tourmaline from Madagascar

This green tourmaline began its story deep beneath the soils of Madagascar, where ancient geological forces concentrated rare elements into crystalline form over millions of years. Miners working small pits and alluvial deposits gently recover tourmaline crystals, each one carrying a fragment of the island's mineral history. This particular crystal stood out for its vivid, intense green, a hue that spoke of chromium and iron in just the right balance. From the moment it was unearthed the gem hinted at something exceptional, a combination of size, color, and natural clarity that rarely survives the journey from rough stone to finished jewel. At The Natural Gemstone Company we value that first connection to the earth, and this tourmaline retains the story of Madagascar in every facet and reflection.

The transformation from rough to a polished gemstone required the hand of a skilled cutter, who chose a cushion shape with a mixed brilliant faceting style to honor the rough stone's natural form while coaxing out maximum brilliance. The faceted cutting style, executed with precision, created a dialogue between deep pavilion facets and a radiant crown, allowing light to travel and return as lively flash and rich green depth. The cutter preserved as much weight as possible without sacrificing symmetry, yielding a finished gem that measures 16.03 x 15.27 x 9.12 mm. The excellent polish gives each facet a mirror finish, enhancing the gem's intense color intensity and allowing the inclusive characteristics to glow rather than obscure. Evaluated at eye level the clarity grade is included, a truthful and honest assessment that reflects natural internal features, which in this stone become part of its character and provenance.

Weight shapes rarity, and the most compelling part of this tourmaline is its impressive 16.10 carat weight. Large, transparent tourmaline specimens of this quality and size are uncommon, and as carat weight increases the per carat value typically rises disproportionately, because collectors and designers prize stones that make a bold visual statement. At 16.10 carats this cushion shaped green tourmaline offers proportions that allow jewelers to craft striking centerpieces, whether set in a statement ring, an elaborate pendant, or a bespoke creation that showcases the stone as the star. The dimensions of 16.03 x 15.27 x 9.12 mm translate to a presence on the hand or at the neckline that is both elegant and unmistakable, a scale that balances wearable comfort with gallery worthy impact. The mixed brilliant cut amplifies the stone's intense color intensity, concentrating green saturation into scintillating facets that change as light and perspective shift, rewarding both the casual admirer and the connoisseur who studies the gem closely.

The story we offer at The Natural Gemstone Company is one of authenticity, and this tourmaline is offered with complete transparency. There is no enhancement, the gem is untreated, and its natural beauty is intact. Its included clarity evaluated at eye level is part of what confirms its natural origin, and the excellent polish ensures that inclusions become part of the gem's inner landscape rather than flaws to hide. For collectors who value provenance, the Madagascar origin ties the gem to a region known for producing some of the world’s most vibrant tourmalines, and for designers seeking a commanding, natural center stone the 16.10 carat weight elevates rarity into desirability. Owning this gem means carrying a piece of geological time, a hand worked treasure from rough crystal to a faceted marvel, and a responsibly presented symbol of the enduring beauty that The Natural Gemstone Company brings to every client.
