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

This 1.06 carat emerald cut bi color parti sapphire presents a study in precise cutting and natural color zoning, attributes that make it an exceptional engagement gemstone for discerning buyers. The stone measures 6.83 by 4.25 by 3.23 millimeters, yielding proportions that result in an approximate depth of 58 percent relative to the average girdle diameter, a proportion that balances pavilion depth and crown height to maximize light return while preserving the stone s natural color distribution. The faceted emerald cut employs broad step facets on the crown and pavilion, creating a hall of mirrors effect that emphasizes clean color planes rather than scintillation, a characteristic that suits a refined, architectural ring design. The cutting style is faceted with meticulous facet junctions and symmetry, and the polish is graded excellent, ensuring crisp facet edges and optimal windowing control, so the parti coloration reads clearly through the table without unwanted haziness.

From a gemological perspective this sapphire offers technical advantages that are ideal for an engagement setting. The clarity grade is very slightly included evaluated at eye level, indicating only minor internal features that do not compromise transparency or durability, and that in many orientations actually enhance the stone s character by contributing to its depth of field. The color intensity is light, with attractive bi color partitioning that displays subtle blue tones alongside near colorless to pale golden zones, a combination that provides versatility in metal choice and mounting orientation. The sapphire is untreated, enhancement free, and originates from Ceylon Sri Lanka, an origin noted for producing clean material with refined hue. For setting considerations the emerald cut s long axis and carefully controlled table invite east west or north south mounting, and the stone s proportions are well suited to a low profile bezel or a four prong basket that preserves the step facets and protects corners. At The Natural Sapphire Company we recommend pairing this stone with settings that respect the step cut geometry, and that allow the parti coloration to be oriented as a design element, creating a modern and technically informed engagement ring that rewards close inspection and daily wear.
