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

This 1.44 carat transparent oval sapphire is an exceptional example of a bi color parti sapphire, measuring 8.12 by 5.96 by 3.87 millimeters, faceted with a mixed brilliant cut, and originating from Ceylon Sri Lanka. The mixed brilliant cut merges a finely faceted crown with a pavilion that balances brilliance and depth, producing scintillation and a pleasing spread of light across the table. The cutting proportions preserve weight while optimizing face up size, which is particularly important in an oval shape where length to width balance enhances wearability in rings and pendants. The clarity is graded as very very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not interfere with the gem's transparency or light performance, and the polish is excellent, permitting clean light return and crisp facet junctions. The stone has been heat treated, a standard and stable enhancement for sapphires that improves color uniformity and removes certain silk inclusions, and this treatment is fully disclosed, which reflects The Natural Sapphire Company commitment to transparent and ethical gemstone practices.

The most striking attribute of this sapphire is its intense bi color display, with pronounced yellow gold and velvety cornflower to violet blue zones that coexist within a single crystal. Parti sapphires like this one are prized for their dual hues and the visual complexity that arises from pleochroism and color zoning, which means the apparent color can shift with viewing angle and lighting, giving the gem a dynamic character. For the educated buyer, the value drivers are clear, color and saturation being primary, followed by clarity, cut quality, origin, and treatment. The intense color intensity places this stone well above washed or pale examples, and the vivid contrast between warm golden tones and saturated blue amplifies rarity, especially for Ceylon origin sapphires where such parti manifestations are esteemed by collectors. The very very slightly included clarity grade supports strong transparency and face up brilliance, while the excellent polish and precise mixed brilliant cutting maximize both sparkle and visual depth. Taken together these attributes yield a gem that is equally attractive to connoisseurs seeking collector appeal and to buyers looking for a showpiece center stone.

Durability is a key consideration for any gemstone investment, and sapphires offer excellent performance for daily wear. On the Mohs hardness scale sapphires rate a 9, which places them immediately below diamond at 10 and on par with other corundum species such as rubies, and above common jewelry materials such as topaz which is around 8, quartz at 7, and various garnets that range lower. This high hardness makes sapphires highly resistant to scratching and wear, suitable for engagement rings and frequently worn jewelry, while still benefiting from sensible care to avoid hard impacts on facet junctions. The heat treatment applied to this stone is stable and does not adversely affect its hardness, but as with all gems, cleaning with warm soapy water and a soft brush is recommended, avoid harsh chemicals and ultrasonic cleaners if you are concerned about historical surface reaching treatments, and professional inspection and cleaning will preserve the stone over decades. At The Natural Sapphire Company we ensure full disclosure of treatments and origin, and we can provide guidance on mounting choices and setting styles that protect the pavilion and girdle while showcasing the exceptional parti coloration, making this 1.44 carat Ceylon bi color sapphire an informed buyer choice that combines rarity, technical quality, and practical durability.
