1.73 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This gemstone began its life beneath the ancient soils of Ceylon, where the monsoon softened the earth and allowed pockets of sapphire to reveal themselves to patient miners. From the moment this crystal was unearthed its clarity and vibrancy suggested a singular destiny, a jewel meant to be admired. At The Natural Sapphire Company we trace each stone back to its origin, and this transparent GIA certified sapphire carries the story of Sri Lanka with every facet. Untreated and completely natural, with no enhancement, it shows the kind of integrity that connoisseurs seek, and its provenance from Ceylon brings a sense of history and mystique. The gem entered the care of master cutters who respected its natural inclinations, allowing the material to dictate the final shape and cut, rather than forcing a preconceived design. The result is a heart shaped gem that still whispers of riverbeds, of sunrise in a tropical isle, and of the old world routes that once carried Ceylon sapphires to emperors and temples.

As a piece that changes color depending on the light, this sapphire reveals a violetish blue that transitions to purple, a living palette that shifts as day moves to evening and as candlelight gives way to electric light. The effect is not a gimmick, but a geological gift, and it is captured in a mixed brilliant cut that balances scintillation with depth. Weighing 1.73 carat and measuring 6.84 x 7.20 x 4.67 mm, the heart silhouette has been cut to maximize both its visual presence and its optical performance. The clarity has been graded as very very slightly included when evaluated at eye level, a testament to the stone being largely free of visible interruption and therefore able to project color and light with boldness. Vivid color intensity and an excellent polish bring every facet to life, so that the surface appears to glow as light plays across it. The GIA certification that accompanies this sapphire gives you documented assurance of its changing hue, weight, dimensions, and the fact that it is uncompromised by treatment, a rarity in the market and an important point for anyone who values authenticity.

When set in jewelry this violetish blue to purple heart will command attention, whether it is placed at the center of a delicate pendant, cradled in a refined ring setting, or balanced within a dramatic halo of diamonds. The mixed brilliant cut throws flashes of brilliance that contrast beautifully with the depth of the color change, so that from one angle the stone will read as a lively slate violetish blue and from another it will read as a sumptuous purple. In a traditional solitaire ring the heart shape speaks directly to sentiment, making this sapphire an ideal token of devotion. In a modern three stone design it will become the luminous focal point flanked by white diamonds that act as a frame and amplifier of its tone. The dimensions allow it to sit comfortably on a finger without seeming oversized, and the 1.73 carat weight gives it presence enough to be noticed across a room without overwhelming an understated design. Set in platinum the cooler metal will intensify the violetish blue aspect, while warm yellow gold can coax out the richer purple notes, so the gem adapts to the personality of the metal and of the wearer.

Choosing a gem is choosing a story, and this heart shaped sapphire carries several threads that make it exceptional. Its journey from Sri Lankan soils to the hands of skilled artisans, its GIA certification, its untouched natural state, its very very slightly included clarity at eye level, its vivid color intensity, and its excellent polish all speak to a gem that is truthful to nature and refined by human craft. At The Natural Sapphire Company we are pleased to offer stones that connect people to place, to tradition, and to timeless beauty, and this color changing heart is a perfect example. Whether you imagine it as an engagement centerpiece, a cherished anniversary gift, or the finishing touch on an heirloom redesign, it will stand out in any jewelry setting because it is alive with color and history, shifting subtly with every movement and light source, inviting admiration and conversation for generations to come.
