10.01 Ct. Orange Sapphire from Ceylon (Sri Lanka)

This exquisite GIA certified orange sapphire from The Natural Sapphire Company is a rare and eye catching choice for an engagement gemstone, with a precise weight of 10.01 carats, dimensions of 12.52 by 13.57 by 8.01 mm, and a heart shape executed in a mixed brilliant cut to maximize scintillation and face up fire. As a member of the corundum family this sapphire benefits from a Mohs hardness of 9, making it exceptionally well suited to everyday wear, and its vivid color intensity is a defining characteristic that speaks to both its visual impact and market desirability. The stone is transparent and evaluated as eye clean at eye level, a clarity grade that is noteworthy for a gem of this size, and the excellent polish enhances light return and the crisp outline of the heart motif. The GIA certification accompanies the sapphire, providing independent verification of weight, measurements, cut style, clarity assessment, color description, and treatment status, and the documented origin is Ceylon Sri Lanka, a source historically prized for bright, saturated sapphires with fine clarity profiles.

For an educated buyer seeking an engagement gem that combines symbolism, rarity, and durability, this heart shaped orange sapphire represents an outstanding option. The vivid orange hue, produced by a combination of trace elements that commonly include chromium and iron, delivers a warm, modern alternative to traditional colorless diamonds, while remaining a hard wearing choice for a lifetime of daily wear. The 10.01 carat size ensures a commanding presence on the hand, and the mixed brilliant cut has been chosen to balance table brightness with internal fire, which is especially flattering in a heart shape where symmetry and facet alignment are critical. The enhancement is heat treatment, an industry standard process that stabilizes and enhances color and clarity, and when disclosed and certified by GIA it is an accepted and permanent treatment. At The Natural Sapphire Company we can provide the full GIA report, recommend secure yet elegant settings that protect the heart points, such as tapered prongs or a partial bezel, and work with you on custom mounting options that showcase the stone while prioritizing wearability. This sapphire is ideal for someone who values gemological authenticity, documented provenance, and a distinctive, meaningful center stone for an engagement ring.
