4.51 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This gemstone is a GIA certified, transparent blue sapphire weighing 4.51 carats, presented in an elegant oval shape with exact dimensions of 11.71 x 9.42 x 5.39 mm. Originating from Ceylon, Sri Lanka, the stone exhibits a vivid color intensity that is evenly distributed across the table and crown. The sapphire has undergone heat treatment, a common and stable enhancement, and it is accompanied by a GIA report that verifies its identity, weight, dimensions, and treatment disclosure. The mixed brilliant cut, combined with an excellent polish, produces a clean, lively face up appearance, and the overall finish demonstrates precise facet junctions and consistent symmetry that support optimal light performance.

The size and clarity of this sapphire make it particularly well suited for a statement piece, whether set as a solitaire, a halo centerpiece, or a bold pendant. At 11.71 mm by 9.42 mm the face up dimensions create significant presence on the finger or neck, and the depth of 5.39 mm results in approximately 51 percent depth relative to the average diameter, a proportion that balances brightness with depth of color. The clarity grade is recorded as very slightly included, evaluated at eye level, which yields a visually clean appearance to the unaided eye while retaining natural formation features when examined under magnification. In practical terms, the combination of substantial carat weight, a broad, deep oval table, and the mixed brilliant facet arrangement ensures strong scintillation and color saturation that read as decisive and refined from a distance, qualities central to a true statement gem.

From a design perspective, this sapphire lends itself to settings that emphasize its scale and tonal intensity. A simple bezel or four prong solitaire will showcase the gem as a singular focal point, while a well-proportioned halo of diamonds will increase perceived size and accentuate the vivid blue without overpowering the stone. The excellent polish enhances facet crispness, making contrast and flash more apparent as the piece moves, and the mixed brilliant cut maximizes return of light through the crown for an appealing balance between fire and depth. The Natural Sapphire Company can provide the GIA documentation and detailed imaging to assist jewelers and clients in setting decisions, and guidance on metal choice, proportioning, and practical considerations for everyday wear, recognizing that heat treated sapphires of this quality are robust for normal use when set and cared for appropriately.
