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

This is a beautifully transparent 1.16 carat oval shape bi color parti sapphire, measuring 6.20 by 4.86 by 4.64 mm, faceted with a mixed brilliant cut that balances scintillation and table brilliance, and presenting a medium color intensity that reads as a refined marriage of cool blue and soft greenish yellow tones across its surface. The stone is eye catching for its gentle bi color distribution, which is visible as complementary zones rather than abrupt banding, and the excellent polish enhances the clean facet junctions so that light flows smoothly across the crown and pavilion. Cut and proportions are important for a gem of this size, and the mixed brilliant approach here optimizes light return in an oval outline, preserving weight while creating attractive fire and brilliance. As a gemstone from The Natural Sapphire Company, this sapphire offers the combination of transparency, thoughtful cutting, and pleasing proportions that collectors and connoisseurs value in a versatile center stone suitable for many jewelry designs.

From a gemological perspective, this sapphire has been graded as very slightly included when evaluated at eye level, which indicates that any internal features are minor and do not detract from the gem visually to the unaided eye, while still providing the internal character that can be appreciated under magnification. Very slightly included is a clarity tier that signals quality, because it denotes a stone that is largely eye clean, with inclusions that are small, well distributed, and typically only apparent to a trained observer using magnification. The mixed brilliant cut complements the clarity grade by dispersing light through multiple facet planes, producing a lively appearance without emphasizing minor inclusions. The excellent polish further contributes to surface integrity, meaning facet planes are smooth and reflective, which maximizes apparent brightness and helps the medium color intensity read cleanly and evenly. In practical terms for an educated buyer, these combined attributes mean you receive a sapphire with reliable optical performance, an attractive face up appearance, and enduring visual appeal that will wear well in most daily settings.

Regarding treatment and origin, this sapphire has been heat treated, which is a widely accepted and stable enhancement applied to sapphires to improve color and clarity, and to stabilize desirable optical properties. Heat treatment of sapphires from Ceylon is a standard and well documented practice within the trade, and when done correctly it improves the stone without compromising structural integrity, and it is considered a normal part of the market. The origin of this sapphire is Ceylon, Sri Lanka, a region with a long and respected history for producing sapphires with lively tones and attractive transparency, borne of classic metamorphic geological environments that foster well formed corundum crystals. For an informed purchaser, origin matters because it helps contextualize expected color palettes and potential market value, and Ceylon sapphires are particularly prized for their bright, lively hues and refined tonal balance. When combined with the documented clarity grade and the fact that the gem is transparent and well polished, the Ceylon origin supports a narrative of geological quality and market desirability that is meaningful to collectors and designers alike.

Beyond the technical details, there is a romantic story woven into the subtle bi color nature and fine clarity of this sapphire, a narrative that makes the gem emotionally resonant as well as technically sound. Imagine a twilight meeting between sea and sky, where the cool lapis blue of evening blends into the pale green of coastal light, a moment of transition captured and held inside a polished oval. The medium color intensity, paired with the very slightly included clarity, suggests a love that is luminous and clear, yet human and authentic, with small internal marks that tell a history rather than diminish beauty. This sapphire invites designs that celebrate duality, such as an east west oval that showcases the color shift across the finger, or a halo setting that frames the blue green interplay and emphasizes sparkle. As specialists at The Natural Sapphire Company, we recommend settings that allow the stone to rotate slightly in wear so that the wearer experiences the subtle color changes, and we advise routine gentle cleaning with warm soapy water to keep the polish at its best. For collectors, designers, and those seeking a meaningful engagement or anniversary gem, this 1.16 carat Ceylon bi color sapphire offers both a rigorous gemological profile and a poetic backstory, combining reliable value with a visual personality that will reward close inspection and daily wear.
