1.28 Ct. Paraiba Tourmaline from Nigeria

This 1.28 carat oval green paraiba tourmaline is a finely proportioned gem, with dimensions of 7.93 x 5.92 x 3.93 mm, cut in a mixed brilliant style to balance scintillation and color saturation. The mixed brilliant cut combines a faceting scheme that emphasizes table and crown brilliance with pavilion facets that return light efficiently, producing lively fire while deepening the perceived color. The stone is transparent and eye clean when evaluated at eye level, a clarity characteristic that allows the intense green hue to read without visual distractions. The polish is excellent, yielding a smooth reflective surface that enhances both brilliance and face up color. Enhancement is disclosed as heat treated, a widely accepted and stable process used to optimize color, and the gem originates from Nigeria, a source increasingly recognized for producing paraiba tourmalines with vivid green and bluish green tones.

From a gemological perspective, this paraiba tourmaline is notable for several reasons that matter to an educated buyer. Paraiba tourmalines are defined by their copper and sometimes manganese trace elements, which produce the neon like, highly saturated blues and greens that are rare among gemstones, and Nigerian material often displays a distinctive intense green with strong saturation. The combination of 1.28 carat weight and eye clean clarity is especially desirable because it preserves both presence and visual purity without requiring magnification to appreciate the stone. The mixed brilliant cut has been executed to maintain depth and table size that enhance the color while still producing attractive brilliance, and the excellent polish maximizes light return and perceived value. Heat treatment here is fully disclosed, transparent, and consistent with industry norms, designed to improve color homogeneity while remaining stable under normal wear. For collectors and connoisseurs, a paraiba tourmaline of this size, cut, clarity, and color intensity represents a rare convergence of market desirable attributes, making it suitable as a focal stone for a fine jewelry commission or as a collectible investment piece.
