6.83 Ct. Cabochon Tourmaline from Madagascar

This is a beautiful translucent 6.83 carat oval bluish green tourmaline, measuring 14.19 x 10.09 x 5.89 mm, presented in a classic cabochon cut that emphasizes color saturation and internal luster. The piece displays an intense color intensity that ranges from deep teal to bluish green as light moves across the dome, and the cabochon shape has been executed with exceptional symmetry, proportion, and an excellent polish that results in striking surface brilliance. Clarity is graded as very slightly included at eye level, indicating minor natural inclusions that do not detract from the gem's visual appeal, and these inclusions can add character while preserving strong translucency. This tourmaline is heat treated to enhance its tone and hue, a common and stable enhancement in tourmalines that is fully disclosed, and it comes from Madagascar, a source known for producing richly colored and collectible tourmaline specimens. The combination of weight, size, intense color, and the skilled cabochon cut makes this stone an immediate centerpiece for a ring, pendant, or cabinet collection, and the smooth dome optimizes light play and apparent depth, creating a sense of internal glow that rivals many faceted stones.

For the educated buyer, key factors that establish value are transparent grading, documented origin, and honest disclosure of enhancements, all provided with this gem by The Natural Gemstone Company. The stone’s 6.83 carat weight at the given dimensions is significant for a cabochon tourmaline, offering versatility for bespoke jewelry or as a museum quality inclusion in a curated collection. The very slightly included clarity grade affirms eye clean appearance in many viewing conditions while confirming natural origin, and Madagascar provenance adds geographic desirability due to the localitys well recorded tourmaline production. Heat treatment is stable and widely accepted within the trade, and the excellent polish and precise cabochon proportions enhance perceived brilliance and wearability. For care, avoid harsh chemicals and hard impacts, clean with warm soapy water and a soft brush, and consider secure bezel or claw settings that protect the dome while showcasing its color.
