4.07 Ct. Blue Sapphire from West Africa

This 4.07 carat pear shape blue sapphire from The Natural Sapphire Company is a study in proportion and optical engineering, with dimensions of 11.72 x 8.53 x 5.88 mm, a mixed brilliant cut, and an excellent polish. The mixed brilliant design combines a brilliant facet pattern on the crown with a modified pavilion faceting scheme, producing both strong scintillation and controlled light return. The crown’s kite and star facets are calibrated to disperse incoming light into vivid flashes, while the pavilion’s faceted planes are angled to capture and redirect that light back through the table, intensifying the sapphire’s vivid blue hue. The result is a gem that displays saturated color without appearing dead, because the cut preserves internal light dynamics and prevents over-darkening at the center while maintaining lively edge-to-edge brilliance.

Craftsmanship details further enhance the stone’s visual performance, the proportional depth of 5.88 mm harmonizes with the length and width to achieve an optimal depth percentage for a pear silhouette, allowing maximum internal reflection without sacrificing face-up size. The pointed tip of the pear is faceted with controlled pavilion facets to concentrate light towards the tip, producing a balanced flash pattern from tip to shoulder, while the rounded base supports a wide, reflective table that anchors color saturation. Clarity is graded as very slightly included when evaluated at eye level, which means minimal inclusions that do not interrupt light paths or detract from overall transparency. The sapphire has been heat treated to enhance color uniformity, a standard enhancement that deepens the vivid blue tone while retaining natural crystal structure, and the excellent polish ensures crisp facet junctions and smooth planes for clean, uninterrupted reflection. Origin is West Africa, and the combination of origin, vivid color intensity, precise mixed brilliant faceting, and expert finishing makes this pear sapphire a technically refined choice for collectors and connoisseurs seeking a gem that maximizes light performance and color saturation.
