2.67 Ct. Green Tourmaline from Brazil

This exceptional green tourmaline from The Natural Gemstone Company is a transparent 2.67 carat gem, precisely fashioned into an Asscher cut, octagon shape, with dimensions of 7.64 by 7.61 by 5.46 millimeters, presenting a compact and elegant profile that wears beautifully in a variety of settings. The gem exhibits a dark color intensity that gives the stone a deep, verdant presence while preserving internal vitality and life across the step facets. Clarity is graded as very slightly included, evaluated at eye level, which means the stone reads clean to the unaided eye in normal lighting, yet retains the character that collectors prize. The polish is excellent, producing crisp facet junctions and reflective planes that enhance the step cut geometry. Importantly, this tourmaline is natural and untreated, enhancement free, and originates from Brazil, a source known for producing fine, richly colored tourmalines. Taken together, these attributes form a gem that is simultaneously market wise and emotionally resonant, an ideal choice for a discerning buyer who values provenance, integrity, and classical cutting precision.

From a gemological perspective, this piece offers several features that will appeal to an educated buyer, including strong color saturation that benefits from the Asscher step cut, and a clarity level that balances rarity with visible purity. The Asscher cut, with its square octagon outline and concentric step facets, tends to deepen perceived color, creating a dramatic central table that concentrates the green hue, while the truncated corners and stepped pavilion add depth and architectural beauty. The clarity description, very slightly included, evaluated at eye level, indicates only minor internal features that do not compromise transparency or light performance, and when combined with excellent polish these inclusions remain unobtrusive. Tourmaline as a species has a Mohs hardness of about 7 to 7.5, offering good durability for daily wear when set thoughtfully, and the refractive properties of tourmaline produce lively sparkle despite the step cut emphasis on color rather than brilliancy. For practical purposes, the measured dimensions and the 2.67 carat weight offer a substantial presence for ring designs while remaining proportionate for pendants and bespoke pieces.

Collectors and jewelers will appreciate the rarity profile and the natural, untreated status of this Brazilian tourmaline, since stones with dark, pure green tones and minimal enhancements are less commonly encountered in the market than heated or irradiated pieces. The green color in tourmaline arises from trace elements and can vary from bluish green to more yellowish green, and this specimen displays a saturated, dark green that reads as sophisticated and classic. Brazil has a long history of producing fine tourmalines, and responsible sourcing from Brazilian deposits offers a provenance story that matters to modern buyers. When considering settings, the Asscher octagon shape pairs exceptionally well with vintage inspired or Art Deco motifs, particularly halo rings with delicate milgrain, bezel settings that emphasize geometric lines, and solitaire designs that allow the step facets to reveal their layered beauty. Care recommendations include avoiding harsh knocks, cleaning with warm soapy water and a soft brush, and periodic inspection of the setting for secure prongs, given tourmaline hardness and the need to protect finely faceted pavements.

As a gift, this green Asscher octagon tourmaline makes a striking and meaningful choice for someone special, offering a combination of aesthetic drama and enduring value that fits occasions ranging from milestone birthdays to engagement celebrations, and from anniversary presents to a carefully chosen heirloom that can be passed down. The deep green tone conveys timeless elegance and can symbolize growth, renewal, and prosperity, while the precision of the Asscher cut communicates thoughtful craftsmanship and refined taste. At 2.67 carats the gem commands attention without overwhelming, and its compact rectangular octagon dimensions sit gracefully on the finger or close to the heart in a pendant. The Natural Gemstone Company stands behind the authenticity and detailed description of this piece, and we welcome inquiries about custom mounting ideas, independent gemological reports, and advice on insurance or appraisal options to ensure the gift is protected and appreciated for generations. Choosing this natural Brazilian tourmaline is a way to present a recipient with a gem that is both visually arresting and responsibly sourced, a meaningful token that will be admired for its color, cut, and the care evident in every facet.
