4.27 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shaped, mixed brilliant cut sapphire from Ceylon, weighing 4.27 carats, measures 11.60 by 7.25 by 5.59 mm, and presents as a beautifully transparent, Other certified Blue gem, with a clarity grade described as very very slightly included at eye level, and a medium color intensity, no enhancement and an excellent polish. At first glance it offers a lively, clean blue that balances saturation and lightness in a way that is distinctively Sri Lankan. The mixed brilliant faceting in the pear shape creates a pleasing interplay of flashes and windowing that enhances the gem s natural transparency, which is particularly valuable for collectors and designers who seek a stone that reads both vivid and wearable. Because it is unheated and retains its natural color, this sapphire carries a rarity premium when compared to many commercial stones that have been heat treated to intensify hue, and it showcases the kind of natural, authentic sapphire character that discerning buyers look for at The Natural Sapphire Company.

When comparing hue and tone to famous Kashmir sapphires, the differences become clear and instructive. Classic Kashmir stones are celebrated for a deep, velvety cornflower blue, often with a slightly softer, more diffuse glow and a rich, saturated tone that can appear almost regal in dimmer light. By contrast this Ceylon sapphire sits at a medium tone with a bright, clear blue that reads cooler and more open, offering superior brilliance and a more luminous face up appearance under varied lighting. Where Kashmir can feel plush and intense, the Ceylon example reads fresher and more lively, making it ideal for those who prefer sparkle and clarity over the deep, mysterious depth associated with Kashmir material. The medium intensity here allows the stone to remain versatile, translating well into multiple jewelry settings and pairing beautifully with both white and warm metals.

Comparing this Ceylon sapphire to classic Burmese and Madagascan examples highlights further distinctions in hue and tone. Burmese sapphires can carry a strong, royal blue with slight velvety depth and sometimes a hint of violet, producing a bold, saturated look that commands attention. Madagascan sapphires vary widely, some presenting vivid, high saturation blues similar to heated gem material, while others show lighter, daylight friendly hues. This Sri Lankan stone positions itself in the middle of that spectrum, avoiding the heaviness of inky Burmese blue while being more vibrant than many pale or watery stones from other locales. Compared with Thai and Australian sapphires, which are often darker, more inky, or leaning toward greenish blue tones, this Ceylon gem preserves a purer blue with a clearer, more crystalline tone. The result is a sapphire that offers both the classic blue identity buyers expect and the approachable brightness that makes it comfortable for daily wear.

Beyond provenance and color, the pear shape and mixed brilliant cut deserve specific attention, because they directly influence how hue and tone are perceived once the gem is set. The elongated pear silhouette concentrates color toward the tip while allowing a wide, faceted pavilion to return light for scintillation and fire. This particular cut was executed with an excellent polish, so the surface reflections and facet junctions are crisp, maximizing the transparent character of the stone. The clarity grade, noted as very very slightly included at eye level, means the gem reads clean to the eye in typical viewing conditions, which enhances perceived color purity and brightness. In practical terms, that clarity combined with the natural, untreated color gives this sapphire an honest presence that does not rely on enhancement to appeal. For customers comparing similar carat weights from other origins, that untreated status, together with the precision of the cut, often delivers superior face up charm and stronger resale desirability, traits we emphasize at The Natural Sapphire Company.

For anyone deciding between sapphires from different regions, this 4.27 carat Ceylon pear shaped stone makes a persuasive case for balanced beauty and lasting value. It is more luminous and wearable than many darker, more heavily saturated stones, and it retains a purity and transparency that can be difficult to find in untreated material from any origin. Its medium color intensity and very very slightly included clarity offer a compelling mix of sparkle and genuine gem character, ideal for a centerpiece engagement ring or a gallery style pendant that benefits from both size and light performance. Because it is unenhanced, certified, and finished with an excellent polish, this sapphire presents a clear proposition to buyers who want authenticity and elegance without compromise. If you are considering a sapphire that sits between the deep, velvety allure of Kashmir and the bold saturation of some Burmese and Madagascan stones, this Ceylon gem from The Natural Sapphire Company offers a uniquely bright, versatile blue that photographs beautifully, wears comfortably, and holds its appeal across changing fashions.
