4.06 Ct. Paraiba Tourmaline from Mozambique

This 4.06 carat cushion shaped paraiba tourmaline from Mozambique exhibits a transparent, neon green hue with medium color intensity, certified for its natural origin and treatment status. The dimensions are 12.62 by 8.90 by 5.67 millimeters, yielding a calculated depth of approximately 52.7 percent, a proportion that indicates a balanced pavilion and crown relationship conducive to strong light return and even face up appearance. The gem is cut in a mixed brilliant style, with a brilliant facet pattern on the crown paired with a modified pavilion that blends step and demi brilliant facets. This combination preserves vivid internal fire while maintaining broad flashes of neon green, the result of copper bearing chemistry that produces the hallmark electric tone of fine paraiba material. Clarity is slightly included at eye level, with small internal features typical for natural Mozambique stones, positioned and oriented so they do not materially interrupt transparency or scintillation. The polish is excellent, with crisp facet junctions and a well centered table that maximizes the stone serviceability and optical performance, and there is no enhancement reported, which preserves its natural appearance and value profile.

For a custom piece, consider designs that exploit the stone geometry and mixed brilliant faceting to maximize scintillation and color saturation. A low profile, open pavilion bezel or four prong setting will permit light to enter the pavilion and enhance the neon glow, while a thin halo of near colorless melee diamonds in F to G color and VS clarity will provide a cool, high contrast field that amplifies perceived intensity without overpowering the green. For a tonal palette, pair the paraiba with medium to dark green tsavorite garnets or demantoid garnets in smaller rounds or trillion side stones to create a layered green composition that reads as sophisticated and cohesive. For contrast, consider soft pink spinels or rhodolite garnets in baguette or oval cuts flanking the center to accentuate the electric neon through warm contrast. Metal choices influence perception, choose 18k rose gold to warm and saturate the green, or 18k white gold or platinum to create a crisp, contemporary contrast. At The Natural Gemstone Company we can provide matching side stone proposals and CAD visualizations to optimize facet alignment and setting geometry, ensuring the paraiba maintains its technical integrity and visual impact in the final bespoke design.
