6.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This C.Dunaigre certified blue sapphire is a technical example of precision cutting and natural material quality, weighing 6.03 carat and measuring 11.04 x 8.41 x 6.65 mm, presented in a classic emerald cut. The emerald cut geometry here employs broad step facets on the crown and pavilion, a large table plane, and clipped corners to control light leakage and emphasize even color distribution across the stone. Facet junctions and symmetry have been executed to yield crisp step lines, producing parallel flash and controlled windowing that preserve the stone s vivid color intensity. Clarity is graded very slightly included at eye level, confirming that inclusions are minimal and do not interrupt the visual field, while excellent polish enhances surface luster and ensures optimal light return. The sapphire exhibits the strong, vivid blue saturation characteristic of Ceylon material, with transparent body color and high transparency that allow for deep, consistent tone without appearing murky. The stone has been heat treated, a stable and industry recognized enhancement that improves color saturation and clarity without compromising structural integrity, and the origin is Ceylon Sri Lanka, a provenance associated with fine blue sapphires and distinguished trace element chemistry.

As a designed heirloom piece, this sapphire combines the durability of corundum with timeless cutting and documentation, making it suitable for multi generational wear and inheritance. The emerald cut is inherently conservative in maintenance, presenting large facets that resist chipping in the crown area and facilitate re polishing or re cutting if future conservation is required. Its 6.03 carat weight and balanced proportions allow for a variety of settings from bezel to low profile prong mountings, options that can protect girdle integrity while showcasing the vivid blue. The C.Dunaigre certificate accompanying the gem documents its origin, treatment, and clarity, forming part of a transferable technical dossier that preserves provenance for descendants. At The Natural Sapphire Company we recommend settings and metal choices that minimize abrasive contact and provide secure mechanical protection, ensuring the stone retains its excellent polish and facet definition through repeated use. This sapphire s combination of precise faceting, verified Ceylon origin, and enduring material properties make it an ideal candidate for a generational heirloom, a piece engineered to communicate technical excellence and aesthetic continuity across generations.
