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

This gemstone is one beautiful transparent 1.02 carat round shape bicolor parti sapphire, with precise dimensions of 5.68 x 5.69 x 4.13 mm, faceted in a mixed brilliant cut and finished to an excellent polish. The stone displays medium color intensity, with a captivating interplay of blue and green tones that is characteristic of parti sapphires from Ceylon, Sri Lanka. The surface and pavilion facets have been cut to balance brilliance and color, enhancing the stone core while allowing the parti color zones to show dynamic shifting as the viewing angle or light source changes. Clarity has been evaluated as very very slightly included at eye level, meaning the stone presents to the unaided eye as essentially clean, with only minute inclusions visible under magnification, which supports both aesthetic appeal and long term structural stability. Importantly, this sapphire is natural and without enhancement, an attribute that significantly increases its desirability and rarity among discerning collectors.

From a gemological grading perspective, several technical details set this sapphire apart for educated buyers. The rounded outline and mixed brilliant cut combine a brilliant crown with a faceted pavilion, a design decision intended to optimize face up brightness while preserving the parti color distribution inherited from the rough. The dimensions produce a depth of approximately 72.6 percent, a proportion that favors deep, saturated color in a relatively small diameter, while still maintaining strong light return thanks to precise facet alignment. The clarity grade of very very slightly included indicates minimal internal features, evaluated at eye level, which means the stone will perform strongly in jewelry settings without visible distractions. Medium color intensity provides an elegant balance, avoiding the overly dark appearance that can diminish sparkle, and avoiding the overly light appearance that can undermine color presence. The excellent polish ensures that facet junctions remain sharp and that light transmission is maximized, factors that directly influence the stone sparkle and perceived value.

Beyond the immediate aesthetic and technical attributes, provenance and treatment status are central considerations for the well informed buyer. This sapphire originates from Ceylon, Sri Lanka, a historic and highly regarded source known for producing sapphires with vibrant, complex hues and strong transparency. Ceylon sapphires commonly exhibit appealing parti coloration and a clarity profile that supports faceted cutting for jewelry. The fact that this stone has undergone no enhancement distinguishes it from the majority of commercial sapphires, which are frequently heat treated to improve color and clarity. Unenhanced sapphires command premium prices because they represent natural color and structure as formed in the earth, a quality that appeals to collectors seeking authenticity and long term value retention. Additionally, the sapphire ranks nine on the Mohs hardness scale, making it one of the hardest and most durable gemstones suitable for everyday wear, a practical quality that complements its collectible value.

When considering an heirloom quality investment, this sapphire meets both emotional and technical criteria needed to endure across generations. The combination of natural, unenhanced color, eye clean clarity, excellent polish, and a classic round mixed brilliant cut yields a gem that will remain stylish and wearable for decades. For setting recommendations that protect and showcase the stone, consider secure four or six prong settings in platinum or high karat gold, or a bezel that provides added protection for the girdle and edges while still allowing light to enter the crown facets. The Natural Sapphire Company can provide provenance documentation, detailed gem reports, and professional appraisals, which are essential for insurance and for preserving the story of the gem as it is passed down. Routine care is straightforward, gentle cleaning with warm soapy water and a soft brush, periodic professional inspections for setting security, and avoidance of harsh chemicals will maintain the stone condition. Over time, the unaltered nature of the sapphire, along with its Ceylon origin and documented history from The Natural Sapphire Company, will strengthen both its sentimental and monetary value, making it a fitting candidate for a generational heirloom piece.
