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

This exquisite transparent cushion shape bi color parti sapphire, weighing 1.19 carats and measuring 6.01 x 5.85 x 4.00 mm, is an exceptional piece for a high end gemstone collection. The stone has been faceted in a mixed brilliant cut, a style that combines the fire of brilliant facets with the depth control of step facets, producing an engaging balance of scintillation and color saturation. The clarity has been graded as very slightly included when evaluated at eye level, indicating that the stone appears clean to a casual viewer while maintaining natural internal character under close inspection. Color intensity is described as intense, and the polish has been evaluated as excellent, ensuring optimal light return and surface brilliance. The sapphire has been heat treated, a common and widely accepted enhancement in the trade that improves color and stability, and its geographic origin is Ceylon Sri Lanka, a source renowned for producing high quality, character rich sapphires. The Natural Sapphire Company stands behind the provenance and description of this gem, offering detailed documentation and professional guidance to collectors and connoisseurs.

From a gemological standpoint this sapphire offers several attributes that appeal to educated buyers. As corundum it has a hardness of 9 on the Mohs scale, which makes it suitable for most jewelry applications while providing lasting durability. Its refractive properties produce strong luster and lively optical performance, and the mixed brilliant cut has been executed to maximize these qualities within the cushion shape. The reported depth of 4.00 mm relative to the face up measurements contributes to a balanced profile, avoiding the overly shallow or deep proportions that can negatively affect face up spread and brilliance. The clarity grade of very slightly included at eye level conveys that inclusions are minor, and that the stone maintains transparency and light performance without significant occlusion. The excellent polish is an important consideration for discerning buyers, because superior polish enhances brilliance, reduces light leakage, and provides the tactile quality expected of luxury gemstones.

The bi color parti nature of this sapphire is a primary reason it will be prized by collectors and designers. Parti sapphires display two or more distinct colors within a single crystal, often enhanced by pleochroism intrinsic to corundum, and in this example the interplay of vivid blue tones with lighter and possibly greenish or golden areas creates a dynamic appearance that changes with viewing angle and lighting. The intense color intensity classification indicates strong saturation where the dominant hues present boldly yet remain balanced across the stone. Heat treatment, when applied with expertise and disclosed to the buyer, can stabilize and intensify natural color zoning without detracting from the stone s rarity, and heat treated Ceylon sapphires are well regarded for their attractive balance of color and clarity. Sri Lanka has a long history of producing high quality sapphires, and its deposits often yield stones with complex and appealing color characteristics, making this specimen both a beautiful wearable gem and an object of gemological interest.

For the educated buyer considering acquisition and long term value, several practical points support the appeal of this sapphire. Natural, transparent sapphires with intense color, excellent polish, and well controlled cutting command attention in the market even when heat treated, because treatment is stable and accepted by connoisseurs when fully disclosed. The cushion shape and mixed brilliant cut make this gem versatile for bespoke rings, pendants, or bespoke collector mounts, and the face up measurements and depth create a visually pleasing spread for its carat weight. We recommend securing a formal gemological report for this stone to document origin, treatment, and measured properties, and The Natural Sapphire Company can assist with laboratory certification and custom setting options. Our team can also advise on insurance grading and long term care, as corundum s hardness makes it suitable for daily wear with routine precautions. For those assembling a curated collection, this 1.19 carat Ceylon bi color parti sapphire represents a rare combination of aesthetic complexity, technical quality, and documented provenance, and it will provide both immediate visual impact and lasting collector appeal.
