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

This sapphire presents as a transparent, emerald cut, bi color parti gem weighing 1.06 carats, a weight that immediately communicates premium quality to a discerning buyer. At just over one carat this stone offers an ideal balance between presence and practicality, providing a substantial face up area while remaining elegantly wearable. The measured dimensions of 5.88 x 4.69 x 3.36 mm yield proportions that are well suited to the emerald cut, with a depth profile that preserves both brilliance and a crisp geometric outline. An educated purchaser will appreciate that carat weight is only one facet of value, yet in this instance the 1.06 carat weight combined with an expertly executed emerald cut produces a visually appealing stone that reads larger than its weight alone might suggest. The Natural Sapphire Company presents this gem as an example of how precise weight, exact dimensions, and refined cutting work together to deliver a premium offering that stands apart from mass market alternatives.

From a grading perspective this sapphire exhibits a clarity grade of slightly included, evaluated at eye level, which conveys meaningful information without overstating its impact on beauty. Slightly included material in sapphire typically indicates small natural inclusions that are often visible only under magnification or when the stone is examined in certain lighting angles, and in this example they do not detract from the stone s overall transparency or its ability to transmit light. The color description as bi color parti with medium color intensity is particularly important to understand, because parti sapphires display two or more distinct body colors within a single crystal, a phenomenon that arises from localized variations in trace element concentrations during crystal growth. Medium intensity is widely preferred by connoisseurs for parti stones, since it preserves the legibility of separate colors while maintaining sufficient saturation to convey depth and richness. Origin is a critical component of valuation for colored gemstones, and this sapphire s Ceylon provenance speaks to a long history of producing gems with lively, transparent tones, and a characteristic clarity that complements the parti color effect.

Heat treatment is disclosed for this sapphire, and it is valuable to clarify what that enhancement means in practical and investment terms. Heat treatment is an accepted and stable enhancement for sapphire, commonly used to improve color uniformity and clarity without introducing foreign substances. When properly disclosed by a reputable supplier such as The Natural Sapphire Company, heat treated sapphires retain long term color stability and predictable behavior, which is essential for both jewelry designers and collectors. The cutting style is faceted in the classic emerald cut, and the combination of excellent polish and precise facet alignment enhances light return and the clean step reflections that define this shape. Excellent polish reduces light leakage at facet junctions, increases surface luster, and contributes to resistance against minor surface wear, all attributes that influence both immediate visual appeal and long term durability.

For an educated buyer considering provenance, trade practices, and resale potential, this sapphire represents a well balanced opportunity. The combination of an authentic Ceylon origin, the attractive 1.06 carat weight, the distinctive bi color parti character, and a clarity grade that confirms natural origin without compromising beauty, together create a stone that is both collectible and eminently wearable. Its dimensions and emerald cut make it versatile for a variety of settings, from classic solitaire rings that emphasize architectural elegance, to bespoke pieces that play on color contrast. The Natural Sapphire Company stands behind full disclosure and can provide detailed measurements, treatment history, and independent gemological documentation upon request, allowing buyers to verify attributes and provenance. For those who value geological rarity, classical cutting, and transparent grading, this sapphire is a compelling example of premium quality, offered with the clarity of information that serious buyers require.
