1.00 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This pear shaped bicolor parti sapphire is a meticulously cut, transparent 1.00 carat gem, measuring 6.82 by 5.10 by 4.07 mm, presented by The Natural Sapphire Company. The mixed brilliant faceting strategy used here combines a brilliant style crown with a more geometric pavilion, creating controlled light return and lively scintillation that accentuates the stone inherent pleochroism. In practical terms, the mixed brilliant cut enhances contrast and sparkle in the lighter zones while preserving depth and saturation in the blue areas, so as the stone is tilted it displays dynamic shifts between blue and yellow green, a characteristic highly sought by connoisseurs of parti sapphires. The gem has medium color intensity, an excellent polish, and a clarity graded as very very slightly included at eye level, details that point to strong transparency and minimal internal disruption to the path of light, increasing both brilliance and perceived size.

From a grading and value perspective this sapphire stands out for several reasons. It is natural and untreated, no enhancement, which is increasingly important to educated buyers who prize rarity and stable color. Origin is Ceylon Sri Lanka, a classic source known for producing well crystallized sapphire rough with appealing tone and saturation, adding provenance value for collectors. The 1.00 carat weight in a well proportioned pear shape yields versatile use in bespoke jewelry, while the mixed brilliant faceting preserves the parti coloration as distinct zones instead of muddling the hues, making it ideal for settings that showcase directional color like solitaire pendants or custom rings. The very very slightly included clarity, evaluated at eye level, means inclusions are minimal and do not interfere with the stone light performance, and the excellent polish ensures crisp facet junctions and strong mirror like reflections. For buyers seeking a scientifically informed, visually compelling sapphire, this gem combines superior cutting technique, natural Ceylon origin, and untreated condition, attributes that together justify its appeal and value.
