2.86 Ct. Green Tourmaline from Africa

This specimen from The Natural Gemstone Company is a beautiful transparent green tourmaline weighing 2.86 carats, presented in a cushion shape with precise dimensions of 8.54 by 7.87 by 5.31 millimeters. The cutting style is faceted with a mixed brilliant cut that combines a faceted crown with a pavilion designed to maximize both brilliance and color depth. The gem displays an intense green color intensity that reads vividly in both daylight and artificial lighting, and the polish has been graded as excellent, producing crisp facet junctions and lively surface reflections. The clarity grade is very slightly included evaluated at eye level, which means the stone is clean to the unaided eye with only minor internal features that do not detract from its transparency or visual appeal. Origin is Africa and the stone has been heat treated, a standard and stable enhancement used to optimize hue and remove unwanted brownish undertones while fully disclosed by The Natural Gemstone Company.

For the educated buyer this tourmaline offers a compelling combination of weight, color, and cutting finesse that explains its market appeal. At 2.86 carats and with the given proportions, the stone sits in a size category that is rare enough to be collectible, yet practical for everyday wear in rings, pendants, and larger earring designs. The mixed brilliant cut is particularly effective for tourmaline because it balances scintillation with strong color saturation, allowing the pavilion facets to return deep green while the crown facets produce lively flashes. The very slightly included clarity grade evaluated at eye level confirms that the inclusions are minimal and do not impede light return, which preserves both brilliance and perceived value. Heat treatment is disclosed and understood in the trade to be a commonly accepted method of enhancing tourmaline color, and when performed correctly it is permanent and stable under normal wear conditions. Tourmaline sits at approximately seven to seven and a half on the Mohs scale, making it durable enough for most jewelry applications with reasonable care, though settings that protect the girdle and corners are advisable for long term wear.

In custom jewelry the visual possibilities for pairing this rich green cushion tourmaline are varied and rewarding. For a classic and highly luminous presentation consider a halo of near colorless round brilliant diamonds to amplify sparkle and provide a neutral contrast that makes the green read more saturated. For a more fashion forward and chromatic approach select warm pink or red accents such as rubellite tourmalines or pink sapphires flanking the center stone, this creates a lively complementary contrast and elevates the green to an almost gemological duet. For a cooler palette choose small blue sapphires or aquamarines to create a refined triad, or introduce yellow sapphires or champagne diamonds to add warmth and a vintage feeling when paired with 18 karat yellow gold or rose gold settings. The cushion outline suits both prong and bezel settings, and the 5.31 millimeter depth offers a comfortable pavilion for secure four to six prong mounting or a subtle bezel with a faceted profile to showcase the mixed brilliant cut. Whether set as a solitaire ring with tapered baguette diamond shoulders, a three stone ring with pink sapphire accents, a pendant surrounded by a diamond halo, or a pair of custom drop earrings matched with complementary colored stones, this green tourmaline will read as a thoughtfully considered centerpiece. The Natural Gemstone Company stands behind the provenance and treatment disclosure for this stone, and we offer bespoke design consultation to help integrate this tourmaline into a custom piece that highlights its intense green color, excellent polish, and eye clean clarity.
