3.10 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This exceptional transparent 3.10 carat oval shape bi color sapphire is a refined and rare addition for a high end gemstone collection. The gem measures 9.45 x 7.25 x 5.74 mm, and the oval silhouette is an elegant classic that lends itself to both contemporary and traditional settings, offering a versatile focal point for a bespoke piece. The stone displays an enchanting bi color range with violet and pinkish lavender tones that shift subtly as the viewing angle changes, a visual character that is highly prized by connoisseurs. With medium color intensity, this sapphire maintains a lively and wearable saturation that reads beautifully in natural daylight and in evening light alike, making it an ideal choice for a collector who values both aesthetic appeal and practical wearability. As offered by The Natural Sapphire Company, this gem carries the provenance and presentation standards that discerning buyers expect, and its transparent clarity and polished finish make it an immediate candidate for a showpiece setting.

From a technical perspective the mixed brilliant cut is engineered to balance maximum sparkle with optimized color return, and in this particular oval the cutter has achieved an excellent polish that enhances scintillation without sacrificing the stone’s color integrity. The mixed brilliant pavilion provides depth and internal reflection, while the faceted crown works to disperse light for lively brilliance and pleasing fire. The clarity grade is very very slightly included, evaluated at eye level, which for practical purposes means the stone reads as eye clean and the inclusions are minute and difficult to detect without magnification. For educated buyers this is an important distinction, because such clarity allows the stone to display its natural color and light performance unimpeded, while retaining the natural character that collectors often prefer in untreated or minimally treated stones. The dimensions and weight are notable for an oval in this color range, giving enough presence to be the central gem in a ring, pendant, or bespoke study piece, while remaining comfortable for everyday elegance.

The origin of this sapphire is Ceylon Sri Lanka, a source with a long and respected history for producing sapphires with bright and lively hues and for yielding stones with subtle and attractive secondary colors. Ceylon sapphires are often characterized by their clear tone and lively saturation, and this bi color example exhibits the geological complexity that Sri Lankan deposits are known for. The stone has been heat treated, a widely accepted and stable enhancement used to improve color and clarity, and this treatment is permanent under normal wearing and cleaning conditions. It is important for collectors to understand that heat treatment is standard within the trade, and that the treated status of this gem has been disclosed to maintain transparency and value integrity. For investors and collectors seeking long term desirability, the combination of Ceylon origin, attractive bi color display, and documented treatment provides a clear and credible profile that supports the stone’s appeal in both private collections and curated museum quality assortments.

When considering setting and care, this oval bi color sapphire lends itself to designs that showcase its color shift, for example a low profile four or six prong setting oriented to highlight the dominant color field, or a bezel setting that protects the girdle while framing the oval for a modern look. For a collector intent on display and longevity, a custom platinum or 18 karat gold mount with a minimal bezel can allow light to enter from the pavilion and maximize the mixed brilliant cut’s performance. Cleaning is straightforward and recommended with warm soapy water and a soft brush, rinsing thoroughly and drying with a soft cloth, and while the stone is heat treated it remains stable, however professional ultrasonic or steam cleaning should be used with caution and only after consultation with your jeweler. The Natural Sapphire Company can provide detailed documentation and photographic records to accompany this gemstone, and we offer guidance on independent gemological reporting should you wish to obtain laboratory certification for weight, cut, clarity, treatment, and origin. For the collector who appreciates technical quality, geological story, and enduring beauty, this 3.10 carat Ceylon bi color sapphire represents a compelling acquisition that will enrich a high end collection for years to come.
