2.98 Ct. Tourmaline from Madagascar

This exceptional bluish green tourmaline, offered by The Natural Gemstone Company, is a transparent 2.98 carat asscher-octagon, measuring 8.76 by 8.44 by 5.66 millimeters, with an asscher cut that emphasizes symmetry and depth. The gem shows medium color intensity, a lively bluish green hue that plays beautifully across the step facets, and an excellent polish that provides crisp facet junctions and bright reflection. Clarity is graded as very very slightly included when evaluated at eye level, indicating only minor internal characteristics that do not disrupt transparency or brilliance to the naked eye. This stone has been heat treated, a stable and commonly accepted enhancement for tourmaline that improves color uniformity without affecting structural integrity, and its origin is Madagascar, a source known for producing well-colored tourmalines. The asscher cut, with its cropped corners and concentric step facets, concentrates light in broad flashes rather than scintillation, making it an ideal choice for collectors who value color saturation and a refined, architectural aesthetic.

For the educated buyer and conscious consumer, this tourmaline represents a blend of aesthetic quality, gemological transparency, and responsible sourcing. Tourmaline rates approximately 7 to 7.5 on the Mohs scale, offering good durability for most fine jewelry uses when set with appropriate protection, and the near-eye-clean clarity and excellent polish maximize its wearable appeal. We are transparent about the heat treatment and provide full disclosure because informed decisions build long-term trust and value. Sourced from Madagascar through our vetted supply chain, this gem is offered with an emphasis on ethical sourcing practices, including traceability to origin and collaboration with suppliers who follow responsible mining and fair labor standards. Such provenance supports a conscious collection, where the buyer can appreciate both the natural beauty and the positive social and environmental considerations behind the stone.

This tourmaline is particularly well suited to a solitaire or halo setting that highlights its asscher geometry and color depth, or to bespoke designs where the gem becomes a central, wearable piece of a curated collection. Care recommendations include avoiding harsh chemicals, sudden temperature shocks, and abrasive impacts, and using warm soapy water and a soft brush for routine cleaning. If you seek a gem that combines precise cutting, eye-appealing clarity, pleasing medium color intensity, and ethical provenance, this Madagascar tourmaline is an excellent choice for the thoughtful collector.
