4.91 Ct. Bi Color Sapphire Crystal from Ceylon (Sri Lanka)

This semi transparent, various shape bi color sapphire begins its story deep within the gem bearing gravels of Ceylon, Sri Lanka, where centuries of monsoon and mountain uplift coaxed corundum into crystalline life. Over millennia this 4.91 carat stone grew in layers, capturing subtle shifts in titanium and iron that created its delicate bi color expression, and the result is a gem with medium light color intensity that seems to change mood as it turns in the light. Mined by skilled hands and sorted by experienced eyes, this sapphire measures 17.90 by 7.00 by 5.60 millimeters, and its clarity is graded included when viewed at eye level, a testament to its natural history and the tiny mineral companions that tell the story of its formation. There has been no enhancement, so what you see is the gem as the earth made it, a rare combination of semi transparency, natural zoning, and authentic Ceylon origin that collectors and connoisseurs prize.

At The Natural Sapphire Company we honored the stone by choosing a rough crystal cut that preserves its original geometry, while applying an excellent polish to reveal inner glow and surface brilliance without erasing the character that makes it singular. Our lapidaries left subtle faces and terminations intact where they enhance the bi color play, turning an unheated crystal into a wearable piece of geological narrative. The included clarity invites a closer, more intimate relationship with the gem, and the medium light intensity offers versatility, lending itself to a sculptural ring or a pendant that showcases length and form. This sapphire is a conversation between earth and artisan, an ethical find from Ceylon that arrives unaltered, ready to be set by you or by our master jewelers into a design that respects its origin and accentuates its natural beauty. If you seek a stone with provenance, personality, and a story to carry forward, this 4.91 carat bi color sapphire from The Natural Sapphire Company is a rare fragment of Sri Lankan geology, polished to shine, and preserved to speak of place and time.
