1.66 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shaped blue sapphire began its journey deep within the ancient rocks of Ceylon Sri Lanka, where heat and pressure over millions of years coaxed trace elements into corundum and painted the crystal with a vivid, resonant blue. Our gemologists at The Natural Sapphire Company discovered this 1.66 carat treasure while inspecting rough material from trusted Sri Lankan sources, drawn to a stone whose transparency and tone promised a special life in a fine jewelry setting. Measuring 10.87 x 5.42 x 3.89 mm, this sapphire was carefully evaluated and graded as very very slightly included at eye level, a clarity that preserves the gem’s natural character without distracting from its brilliant presence. The cutter respected that natural personality, choosing a mixed brilliant cut to marry scintillation with depth, and shaping the stone into an elegant pear that feels both classical and modern. The gem was heat treated, a widely accepted enhancement for sapphires that gently refines tone and clarity while remaining fully natural in origin, and the final polish is excellent, creating a surface that mirrors light and reveals the sapphire’s lively internal glow.

From the mine to the workbench, this stone’s transformation is a tale of both geology and human skill. After careful selection we studied the rough to determine the ideal orientation that would maximize color distribution and weight retention, aiming to create a pear that would sit gracefully in a ring or pendant while showcasing the vivid color intensity that is so characteristic of fine Ceylon sapphires. The mixed brilliant cut was chosen for its ability to return light in a dynamic fashion, combining the fire of a brilliant style with the elongated silhouette of a pear to create flashes of blue and electric sparkle as the wearer moves. At 3.89 mm depth the gem retains beautiful face up presence and sits comfortably in bezel or prong settings, while the measurements ensure a balanced profile for custom designs. The very very slightly included grade gives this stone authenticity, allowing small natural fingerprint like inclusions to testify to its origin, while the excellent polish guarantees a smooth, reflective finish that enhances visual impact and everyday resilience.

When comparing this natural Ceylon sapphire to lab grown alternatives it helps to think about story and scarcity as much as about optical properties. Lab grown sapphires have the advantage of predictable color, consistent clarity, and often a lower price, and they have an important place in the market for certain budgets and design needs. Natural sapphires like this one from Sri Lanka, however, carry a provenance that cannot be reproduced in a laboratory, an origin story that connects the wearer to a particular place on the globe and to the hands of miners and cutters who shepherded the gem into being. Natural inclusions are not flaws to be erased but signatures of formation, tiny maps of geological history that many collectors and connoisseurs prize for the authenticity they confer. Because each natural stone is unique collectors and buyers often find that natural sapphires maintain desirability over time, and heat treatment performed under controlled conditions is widely accepted by gemological labs and the trade as a means to reveal the gem’s best color without altering its natural identity. At The Natural Sapphire Company we document origin and treatment where possible, and we stand behind each stone with transparency about enhancements and sourcing, so that your choice is informed and your connection to the gem is real. If you seek a gem that combines a story beginning in ancient earth, the refined hand of a skilled cutter, and the enduring appeal of a vivid Ceylon blue, this 1.66 carat pear shaped sapphire offers a rare convergence of nature and craft that lab grown alternatives cannot replicate, and we invite you to experience its color and character in person or through a detailed consultation.
