1.68 Ct. Tourmaline from Mozambique

This transparent green tourmaline is presented with exacting technical detail to satisfy the discerning collector, it is a pear shaped elbaite weighing 1.68 carat, with dimensions 10.22 x 5.94 x 4.38 mm, cut in a mixed brilliant style to balance weight retention and optical performance, the faceting plan combines a brilliant cut crown with a step influenced pavilion geometry to maximize scintillation while preserving a clean window free of windowing, clarity is evaluated as very slightly included at eye level, color intensity is intense, polish quality is excellent, enhancement status is none, origin is Mozambique, and provenance and release are documented by The Natural Gemstone Company. The combination of weight, dimensions and pear outline produces a precise visual balance, the elongated silhouette optimizes face up color, and the mixed brilliant faceting allows the cutter to manipulate return of light in a gem material with a refractive index in the range typical for tourmaline. This description emphasizes measurable attributes, so the buyer receives an accurate expectation of performance in finished jewelry and design applications.

The narrative of formation stretches back millions of years, into the late stages of granitic fractionation where boron enriched hydrothermal fluids migrated along fractures and formed zoned pegmatitic bodies in the crust, in these high temperature, slow cooling environments elbaite nucleated within cavities and fractures, growth proceeded by rhythmic layering and sector zoning, trace elements such as iron and possibly chromium substituted into the crystal lattice to produce the green hue, the chemistry of the local host rock, including availability of alkalis, boron and volatile components, controlled the saturation path and the eventual crystallization of sizable prismatic crystals, fluid inclusions, healed fissures and growth tubes became trapped during growth providing a record of the physicochemical conditions, over geological time uplift and erosion exposed pegmatites in the Mozambique district where miners selectively recovered gem quality prismatic crystals, this specimen therefore encapsulates a geologic history of fluid evolution, crystal chemistry and structural control that is evident to the trained eye in its zoning, inclusion textures and inherent pleochroism.

On a technical level of cutting and finish, the mixed brilliant cut on this pear shape was executed to reconcile the inherent anisotropy and birefringence of tourmaline with the goal of presenting a saturated face up color and lively facet contrast, the crown facets are arranged to produce tight scintillation and to refract light into the pavilion where a controlled set of facets redirects light back through the table for maximum color saturation, facet junctions demonstrate high precision, facet symmetry is maintained along the long axis to preserve a stable optical pattern, girdle thickness was controlled to allow secure setting without excess removal of weight from the pavilion, pavilion angles were selected with the refractive index and dispersion of tourmaline in mind to avoid light leakage and to enhance return when viewed in typical lighting conditions, polish on each facet shows a mirror finish and is consistent with excellent polish grading, the clarity grade of very slightly included at eye level indicates inclusions are present but do not materially disrupt the optical performance, such inclusions are typical internal growth features and do not indicate fracture related instability, because no treatments were applied the cutter preserved natural zoning and clarity characteristics, the result is a gem that balances optical performance with structural integrity and natural character.

For the jeweler and end user who values technical provenance and cutting philosophy, this green pear tourmaline presents predictable behavior in a variety of mounting options, the elongated pear silhouette benefits from a pointed bail or a secure prong configuration that supports the tip and distributes stress away from the girdle, orienting the gem to showcase the primary pleochroic axis will reveal the most desirable green saturation under mixed light, the intense color intensity allows designers to use the stone as a primary focal point, while the very slightly included clarity grade and excellent polish ensure surface reflections remain clean and uninterrupted, The Natural Gemstone Company stands behind the natural origin and the no enhancement declaration, documentation of origin from Mozambique accompanies this gem, and our cutters and gemologists are available to provide objective commentary on setting recommendations and light orientation to optimize face up performance, for the technical buyer who seeks a balance of deliberate cutting choices, natural formation history and measurable gemological attributes, this pear green tourmaline offers a rare combination of geological story, refined faceting, and practical durability for fine jewelry applications.
