1.78 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.78 carat oval blue sapphire from Ceylon Sri Lanka is a fine example of classic, wearable rarity, measuring 6.99 by 5.91 by 4.58 mm, with a mixed brilliant cut that balances scintillation and depth. The stone is transparent, displaying vivid color intensity and an excellent polish that maximizes face up brilliance. Clarity has been evaluated as very slightly included at eye level, which means the small natural inclusions do not detract from its visual impact when set, but do serve as a fingerprint of natural origin. The sapphire has been heat treated, a stable and widely accepted enhancement that improves color and clarity while remaining permanent when cared for properly. The combined attributes of a lively Ceylon blue, a precise mixed brilliant facet arrangement, and a clean face up appearance make this gem both immediately appealing and technically robust in quality.

For an educated buyer seeking a generational heirloom, this sapphire offers the key qualities that sustain value across decades. Sapphire rates a nine on the Mohs scale, ensuring excellent resistance to everyday wear, and the excellent polish and enduring color stability from standard heat treatment mean the gem will retain its presence through repeated use and periodic servicing. Its 1.78 carat weight sits in a size range that reads as significant on the finger while remaining versatile for many designs, demonstrated by scale images that show elegant proportionality when worn. Provenance from Ceylon adds desirability, as Sri Lankan sapphires are historically prized for their bright, lively blues, and the documented clarity assessment and treatment disclosure support transparency and future resale. At The Natural Sapphire Company we carefully select and document stones with these enduring qualities, and we recommend settings that protect the pavilion and girdle, routine inspections, and professional cleaning to ensure this sapphire can be reset and enjoyed by future generations, becoming a true family heirloom.
