1.70 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

There is a long and noble lineage to gemstones that wear both color and clarity like a mantle, and this 1.70 carat transparent emerald cut bi color, parti sapphire carries that lineage with calm authority. Sourced from the storied mines of Ceylon, Sri Lanka, this stone measures 7.10 by 5.75 by 4.27 millimeters, it is faceted in a classic emerald cut that calls to mind the stepped faceting of antique stones and the architectural lines of period jewelry. The gem presents as transparent with medium color intensity, and an eye level clarity that is slightly included, a trait that speaks to natural formation rather than heavy human alteration. The polish is excellent, allowing each step to catch and release light in a measured rhythm, and importantly this sapphire has no enhancement. For those who prize provenance and authenticity, the unheated Ceylon origin of this parti sapphire connects the wearer to centuries of gem trading across the Indian Ocean, to legendary courts and temple offerings, and to the quiet skill of cutters who have long shaped Sri Lankan stones for the world.

The emerald cut is a deliberate choice that heightens the particolored nature of this sapphire, it frames the interplay between a soft, watery cornflower blue at the corners and a near colorless, luminous heart that alternates between cool and warm tones as the stone moves. Where a brilliant cut scatters light into a lively constellation, the step facets of this cut create broad flashes of tone that reveal the parti coloring like bands of ancient silk. Slight inclusions visible at eye level lend character rather than detracting, they declare the gem as a natural product of geological time, while the medium color intensity keeps the palette subtle and refined. The overall effect is of a gem that can read as nearly colorless in one moment and gently blue in the next, a property prized in antique and heirloom pieces for its quiet drama and enduring elegance.

Comparing the hue and tone of this Ceylon parti sapphire to gemstones from other celebrated locales brings its personality into clearer relief. Kashmir sapphires are famous for an almost velvety, saturated cornflower blue with a soft silkiness that is rare and deeply coveted, they tend to be more uniformly saturated than this parti stone. Burmese sapphires often carry a strong, royal blue with intense chroma that reads as bold and resplendent on the finger, they are more consistently rich than the delicate tonal shifts of the Ceylon parti. Madagascar sapphires can show vivid and varied blues close to the Ceylon spectrum, yet they frequently present with more uniform saturation and fewer near colorless zones. Australian sapphires commonly show deeper, inky blue greens that convey earthy strength rather than the airy refinement of this emerald cut parti. Montana sapphires from the United States are known for their softer, pastel teals and cornflower tones, and in that company the Ceylon piece finds a congenial neighbor, sharing a propensity for delicate blue notes, while distinguishing itself through the striking contrast between its clear center and blue extremities. Each region contributes a different voice to the sapphire chorus, and this Sri Lankan stone speaks in a refined, historical register that balances light and color like a practiced orator.

When set, the classic geometry of the emerald cut will pair beautifully with designs that honor tradition, from solitaire rings with simple claws to low bezel settings that echo Victorian restraint, and The Natural Sapphire Company is proud to present this gem for clients who seek a piece that can become an heirloom. The stone wears its history without ostentation, making it ideal for an engagement ring that signals discernment, a pendant anchored in quiet luxury, or a signet style that favors architectural silhouettes. Care is straightforward, gentle cleaning with warm soapy water and a soft brush preserves the excellent polish and the natural luster that defines this sapphire, while routine inspections of the mounting will keep the gem secure for generations. Because it is unenhanced and originates from Ceylon, the gem carries a story that can be retold with each passing hand and each new owner, a story of island mines and skilled cutters, of trade routes and temple offerings, of the enduring human impulse to shape beauty from stone. For those who value legacy, nuance, and natural origin, this 1.70 carat emerald cut bi color, parti sapphire offers a rare combination of classical form and singular color play, a jewel that bridges ancient tradition and contemporary elegance.
