1.28 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This heart shape blue sapphire, weighing 1.28 carats, presents an exceptional balance of size and brilliance that will be appreciated by an educated buyer. Measuring 5.97 by 6.50 by 4.04 millimeters, the gem has a depth proportion of approximately 65 percent, a profile that supports strong light return while preserving a pleasing face up spread. The mixed brilliant cut has been executed to maximize scintillation and color dispersion, and the excellent polish enhances the gem's mirror like facets. Clarity is graded as very slightly included when evaluated at eye level, meaning that the minor inclusions do not detract from the stone's transparency or visual appeal but instead serve as natural fingerprints that confirm its natural origin. The intense color intensity, typical of fine Ceylon sapphires, offers a vivid blue that sits between classic cornflower and deep royal tones, and the stone has been disclosed as heat treated, a stable and widely accepted enhancement that enhances color and clarity while being standard practice in the trade.

From a value perspective the 1.28 carat weight is a key factor that elevates this sapphire above smaller counterparts, because sapphire pricing increases on a non linear scale as carat weight grows. Heart shapes require skilled cutting and reduce rough yield, so a heart shape over one carat from Ceylon is relatively rare and commands a premium for both rarity and craftsmanship. For an investor or connoisseur, the combination of significant carat weight, intense Ceylon blue, very slightly included clarity at eye level, and excellent polish creates a gem that will perform well as a center stone in a fine ring, pendant, or heirloom piece, while retaining collectible appeal. At The Natural Sapphire Company we emphasize full disclosure and transparent grading information, and this sapphire is offered with all relevant details so you can assess its provenance, enhancements, and market position with confidence. If you are seeking a heart shape sapphire that balances presence, beauty, and rarity, this 1.28 carat Ceylon gem is a compelling choice.
