5.59 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent blue sapphire weighs 5.59 carats, presented in a classic oval shape with precise dimensions of 12.08 x 9.81 x 5.79 mm, and it is finished with a mixed brilliant cut that maximizes light return and scintillation. The gem displays a medium intense blue color that sits in the highly sought after Ceylon spectrum, offering a clear, vivid presence without veering into overly dark saturation. Clarity is graded as very slightly included when evaluated at eye level, which means the stone appears clean to the naked eye while retaining natural internal characteristics under magnification, a quality that discerning buyers often prefer as a marker of authenticity. The polish is excellent, giving crisp facet junctions and an even surface that enhances brilliance and wearability. This sapphire has been heat treated, a stable and widely accepted enhancement that improves color and clarity while preserving the integrity of the crystal, a factor experienced collectors and gemologists understand and accept when assessing both beauty and value.

Provenance is an important consideration for educated buyers, and this sapphire originates from Ceylon, Sri Lanka, a source with a long and celebrated history for producing blue sapphires that combine lightness with clarity and lively brilliance. Historically, sapphires from Ceylon were prized by royalty and spiritual leaders, used as talismans for protection, wisdom, and good fortune, and set into ceremonial jewelry across trade routes stretching from Asia to Europe. This stone embodies that heritage through its refined hue and classic oval silhouette, making it equally suited for a traditional halo engagement setting or a museum style solitaire that highlights origin and cut. At The Natural Sapphire Company we document origin and treatment clearly, and we present stones like this one with transparent grading details because provenance, cutting, and finish contribute as much to long term value as carat weight alone. For collectors and connoisseurs who prioritize a balance of natural character, measured clarity, and classic Ceylon color, this sapphire represents a rare opportunity to acquire a gem that carries both historical resonance and contemporary desirability.
