19.03 Ct. Tourmaline from Africa

This specimen is a transparent bluish green tourmaline weighing 19.03 carat, presented in a cushion shape with dimensions 18.70 by 12.20 by 10.50 mm. The gem has been fashioned with a fancy cut designed to maximize scintillation and internal light movement, and it exhibits a medium intense color intensity consistent across the pavilion and crown. Clarity has been evaluated at eye level as eye clean, providing an unobstructed visual field for the play of color and internal reflections. The polish on all facets is excellent, creating crisp facet junctions and a refined surface finish. The material is heat treated, a disclosed enhancement commonly used to optimize color uniformity, and the piece is sourced from Africa, providing a clear provenance that is documented by The Natural Gemstone Company.

Optical performance is a defining attribute of this tourmaline, the fancy cut delivering a starburst of light that radiates from the center and accentuates the bluish green hue. The gem is transparent, allowing light to traverse the stone and engage the internal facet architecture, which in turn emphasizes brilliance and saturation. Tourmaline is durable enough for fine jewelry applications with a Mohs hardness in the range of 7 to 7.5, and the combination of excellent polish and eye clean clarity makes this piece particularly well suited for rings, pendants, and bespoke designs where the stone is intended to be a primary focal point. Because the stone has undergone heat treatment, standard gem care practices are recommended, including avoiding abrupt temperature changes, exposure to harsh chemicals, and prolonged high heat during setting. For secure mounting and long term wear, settings that protect the girdle while allowing light to enter the pavilion are advised.

The color and clarity of this tourmaline lend themselves to a quiet, romantic narrative, the bluish green hue evoking the calm depth of a coastal lagoon where two people first recognized a rare kinship. The transparency, evaluated as eye clean, suggests a relationship built on clarity and mutual trust, each facet of the cut reflecting shared moments and private understandings. In this narrative the heat treatment is analogous to a quiet refinement, a moment of intentional care that reveals the truest color beneath, and the African origin speaks to a distant landscape that becomes part of the stone bearer’s personal geography. At The Natural Gemstone Company we document each step of the gem journey, offering provenance and treatment disclosure to inform thoughtful design decisions. This tourmaline is presented as a considered choice for a client seeking a distinctive center stone with measured brilliance, reliable durability, and a poetic color story that can be translated into a lasting piece of jewelry.
