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

If you are searching for a statement gem that resolves the search for the perfect engagement stone or a rare centerpiece for a serious collection, this 1.71 carat round bi color parti sapphire answers that call beautifully, and at The Natural Sapphire Company we are proud to present it to you. This transparent sapphire measures 7.51 by 7.50 by 4.19 millimeters, a lovely near perfect round, and carries the vivid story of its Ceylon origin. Bi color and parti sapphires are prized for their natural color variations, and this example offers intense color intensity that shifts and interacts with light in a way that feels alive, making it a uniquely personal focal point for a ring, pendant, or a curated collector display. For a buyer who seeks more than conventional color and size, this gem blends rarity, wearability, and visual drama into one stone, delivering the emotional impact expected of an heirloom quality gem.

What truly elevates this sapphire into the category of must-have showpieces is the skilled faceting and the mixed brilliant cutting style. The mixed brilliant cut is designed to combine the scintillation and return of a brilliant crown with pavilion faceting that deepens color and creates alluring flashes, and in this stone those facets have been balanced to maximize both brilliance and color play. The excellent polish ensures that each facet edge is clean and reflective, so when you turn the stone it responds with lively scintillation and strong light return. The clarity has been assessed as slightly included at eye level, which means the gem remains visually engaging and largely eye-clean in everyday wear, while retaining the natural inclusions that authenticate its origin and individuality. The result is a gem that reads as intense and lively to the eye, the kind of stone that captures attention in a room and photographs with depth and character.

This sapphire has undergone heat treatment, a widely accepted and stable enhancement that intensifies color and refines tone while respecting the gem’s natural character. Heat treatment is standard practice for Ceylon sapphires and when disclosed, as we always do at The Natural Sapphire Company, it provides confidence in the stone’s enduring beauty and stability. The combination of Ceylon provenance, the parti color phenomenon, and the mixed brilliant faceting creates an irresistible balance for customers who want both rarity and reliability. At approximately 7.5 millimeters across, this sapphire is highly versatile, well suited as a striking solitaire, a centerpiece for a halo or three-stone engagement ring, or set into a bespoke pendant where the bi color nature can be showcased. Collectors will appreciate the stone’s distinctive personality and the way its inclusions and color zoning tell the story of its geological journey.

When your priority is finding a gem that closes the search and becomes the new standard in your collection or the defining element of a bespoke piece, this 1.71 carat Ceylon bi color parti sapphire presents the complete solution. We at The Natural Sapphire Company are here to guide you through setting options that best show off the mixed brilliant cut and the parti color range, from open prong solitaires that let light flood the pavilion, to detailed halo designs that amplify perceived size and brilliance.
