3.81 Ct. Green Tourmaline from Brazil

This transparent 3.81 carat oval green tourmaline measures 11.91 x 8.78 x 5.67 mm, yielding a depth percentage of approximately 47.6 percent, a proportion that supports even light return and stable color saturation in an oval outline. The stone is faceted to a mixed brilliant scheme, combining a brilliant-cut crown with a carefully faceted pavilion to optimize scintillation while preserving the gem’s rich body color, and the excellent polish produces crisp facet junctions and minimal surface departure for maximum luster. Clarity is graded eye clean at typical viewing distance, indicating the absence of inclusions that would interfere with visual performance, and the vivid color intensity is a true, saturated green with strong tone uniformity across the crown, suggesting careful orientation of the host crystal during cutting to manage pleochroic behavior. This specimen is natural and untreated, no enhancement, originating from Brazil, and presents a true representation of tourmaline character, including stable refractive response and a substantive, pleasing heft consistent with tourmaline specific gravity in the low threes.

As a generational heirloom this green tourmaline is well suited to long term ownership, due to its combination of substantial size, classic oval geometry, and unenhanced origin, three factors that preserve both intrinsic and market value over time. Tourmaline’s Mohs hardness of approximately 7 to 7.5 affords daily wearability when set with protective design choices, such as a well-engineered bezel or a low-profile four-prong cathedral, metals like 18k gold or platinum that resist deformation, and rub-over settings that protect the girdle. Because the cutting proportions balance depth and table area, the gem can be reset or remounted without need for re-cutting, preserving weight for descendants, and the eye-clean clarity ensures future polishing will not compromise appearance. The Natural Gemstone Company provides provenance and handling documentation which should be retained with the piece, and I recommend baseline photographic records, a professional appraisal, and periodic setting inspections to maintain structural security. With these practices, this Brazilian, mixed-brilliant, vivid green tourmaline becomes an enduring, wearable legacy that can be adapted by future generations while retaining its optical character and value.
