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

There is a long and noble story behind every Ceylon sapphire, a story that carries centuries of trade and admiration from royal courts to modern collectors, and this oval bicolor or parti sapphire is a living fragment of that tradition. Weighing 1.00 carat and presented in a classic oval silhouette, this gem measures 6.96 x 4.83 x 3.32 mm, dimensions that speak of balanced proportions and an enduring sense of refinement. Mined in Sri Lanka, historically known as Ceylon, this sapphire arrives completely natural, with no enhancement, a fact that elevates its rarity and its appeal to those who prize authenticity and provenance. The intense color intensity of the stone is a testament to the rich soils and geological history of its homeland, and the transparent nature of the crystal allows light to travel through and animate the dual tones within, creating a jewel that feels both ancient and vividly alive. When you choose a gem such as this, you are selecting more than a piece of jewelry, you are embracing a legacy that has been shaped by time and cultural reverence, and you are setting the stage for a treasure that can be passed from one generation to the next.

The cutting of this sapphire is a careful conversation between tradition and modern gem cutting mastery, expressed through a faceted mixed brilliant cut that maximizes both depth and surface flash. The mixed brilliant approach places a brilliant style on the crown to capture scintillation and lively white light return, while offering proportional pavilion facets that contribute to internal life and color saturation. The clarity is described as very slightly included when evaluated at eye level, a grade that offers a jewel with near eye clean appearance that still bears the tiny signatures of its natural formation, inclusions that tell the story of the stone without diminishing its beauty. The excellent polish enhances every facet junction, producing crisp facet lines and mirrorlike surfaces that cooperate with the mixed brilliant scheme to deliver controlled brilliance and sparkling flashes as the gem moves. In an oval shape with these exact measurements, the sapphire will present an elegant elongation on the finger, a graceful footprint in a pendant, and a versatile presence in a pair of earrings, each application carrying the hallmark of classic design.

How a sapphire reveals itself depends as much on light as on cut, and this unheated bicolor sapphire is especially poetic in its transformations. In bright daylight, particularly when the sun is high and the light is broad, the intense colors become emphatic, the dual hues standing distinct yet harmonizing, one tone warming as the other cools, with broad flashes of brilliance across the crown facets. Morning light, which often carries a soft, cool quality, tends to accentuate the crisper, cooler component of the stone, lending it an almost crystalline clarity and a lively, energetic scintillation from the mixed brilliant facets. Under afternoon or golden hour light, the warmer side of the parti coloration deepens, and the gem seems to glow from within, the transparent body allowing subsurface reflections to mingle with surface sparkle, producing a depth that is both antique and immediate. Artificial lighting offers further variety, with incandescent light softening contrasts and emphasizing the warmer shades and candlelight creating a romantic, enveloping glow that highlights the stone as an intimate emissary of color. Cooler LED or fluorescent lighting enhances brilliancy and can make the cooler color component sing, causing vivid flashes and an almost electric contrast between the two tones. Across these settings, the excellent polish and mixed brilliant facets ensure that light is always managed with intention, delivering both lively surface scintillation and moments of internal fire.

This sapphire is an ideal candidate for a classic setting that honors its heritage and its inherent beauty, a setting that will allow the bicolor nature to be admired from multiple angles and that will become part of a family narrative. A simple solitaire in a timeless mounting allows the stone to command attention, while a halo of fine white stones will elevate the central color and add a period feel evocative of vintage heirlooms. For those who favor tradition, a low profile bezel or a four prong oval setting in platinum or warm gold will complement the gem and ensure it endures as an object of reverence. At The Natural Sapphire Company we place great emphasis on provenance and natural state, and this gem comes with the assurance of unenhanced origin, truthful description, and the expertise to recommend settings that preserve and showcase its natural character.
