1.81 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the heart of Ceylon to your jewelry box, this 1.81 carat oval blue sapphire carries the story of ancient geology and careful human hands, The Natural Sapphire Company sourced this gem from Sri Lanka where corundum crystals form under high heat and pressure deep within the earth, over millions of years these crystals grew in a trigonal lattice that gives sapphire its inherent toughness and play with light, the rough stone was handled by experienced local miners and then entrusted to master cutters who revealed its potential, the result is a transparent oval weighing 1.81 carat, measuring 8.72 by 6.17 by 4.06 mm, faceted with a mixed brilliant cut that balances a faceted crown and pavilion for optimum brilliance, the gem presents vivid color intensity, an eye clean clarity at standard viewing distance, and an excellent polish that finishes each facet with mirror like precision, a gentle heat treatment was applied to stabilize and intensify the blue, a common and accepted enhancement which enhances the sapphire s natural beauty without compromising its integrity.

What makes this sapphire sparkle in a way few stones can match is a combination of its internal structure and the skillful cutting it received, corundum s refractive index, which lies around 1.76 to 1.77, bends and traps light within the crystal so that every facet becomes a pathway for reflected rays, the mixed brilliant cut multiplies those pathways, small triangular and kite shaped crown facets catch light and scatter it as scintillation, while the pavilion s carefully angled facets return light to the viewer s eye, this interaction produces strong flashes of brilliance and a lively play of light across the surface, the sapphire s vivid blue benefits from subtle pleochroism, a property that shows slightly different tones when the stone is tilted, the cutter used that quality to orient the table and depth so that the most saturated blue faces the viewer, with eye clean clarity there are no visible inclusions to interrupt the light s travel, the result is a gem that glows from within, a classic Ceylon blue brought to life, The Natural Sapphire Company invites you to feel that journey, to own a stone whose origin, structure, and craftsmanship come together as a single expression of timeless beauty.
