Sourced from the historic gem fields of Sri Lanka (Ceylon), this 1.65 Carat Natural Loose Blue Sapphire showcases a vibrant, classic cornflower-to-royal blue hue prized for its lively light return. Precision-fashioned into an elegant oval cut, its symmetrical faceting scatters light evenly across the crown, enhancing both its optical depth and brilliance. The stone features high eye-clean clarity and outstanding transparency, allowing light to travel freely through the crystal without visible internal inclusions or dark extinction areas dulling its tone. Naturally untreated, this 1.65-carat Ceylon gemstone offers balanced dimensions and rich color saturation, making it a sophisticated center stone for a custom engagement ring, a halo pendant, or a fine sapphire collection.
