3.75 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are looking for a sapphire that stops the search, that balances presence on the hand with an unmistakable natural beauty, this 3.75 carat pear shape Ceylon blue sapphire answers that need directly. Many clients come to us seeking an engagement centre stone that feels both substantial and effortlessly elegant, or a collector who values provenance and unimproved gem quality. This sapphire fulfills those desires. It is transparent and unheated, with an intense color that reads as a bright, living blue in daylight and as a deep velvety blue in indoor lighting. For someone who wants the certainty of a gem that will attract attention without needing treatment to achieve it, this stone is the ideal solution. At The Natural Sapphire Company we specialize in sourcing sapphires with clear origins and clear stories, and this example from Ceylon combines that heritage with a size and shape that is both modern and timeless.

Technically this sapphire measures 12.65 by 7.03 by 5.37 millimeters, and its pear outline makes it exceptionally flattering set as a ring or pendant. The mixed brilliant cut brings a purposeful balance between table and crown facets to maximize scintillation and color return, and the excellent polish means every facet edge is crisp and lively. Clarity is described as very very slightly included when evaluated at eye level, which translates to an eye clean appearance for most viewers and exceptional transparency that allows light to pass and reflect with minimal obstruction. This clarity, combined with the stone being entirely without enhancement, means you are looking at natural material that displays its color and light behavior exactly as it formed. The intense color intensity is one that appeals to buyers who want a sapphire that reads as richly blue from any angle, without veering towards a gray or washed out tone. The pear shape also offers versatility, pairing beautifully with both classic and contemporary settings, and the overall weight of 3.75 carats ensures the piece will feel significant when worn.

When comparing brilliance to more common gemstones, this sapphire stands apart in ways that matter to both the heart and the eye. Diamonds, with their higher refractive index around 2.42, and moissanite, with an even higher refractive index near 2.65, are renowned for their white light fire and dramatic sparkle. Sapphires register a lower refractive index around 1.76 to 1.77, and their dispersion or spectral fire is naturally less than that of diamond or moissanite. However, what sapphire brings to the table is a concentrated color brilliance and depth, especially when the hue is intense and the stone is eye clean. Where diamonds scatter white light into flashes, a fine blue sapphire like this one channels light into saturated blue flashes and blue violet flashes because of the gem’s inherent color chemistry and subtle pleochroism. Compared to white sapphire or topaz, which can lack depth of color and may appear more glassy, this Ceylon stone has dimensional color, so light seems to come from within the gem rather than just bouncing off the surface. The mixed brilliant cut enhances this internal glow by creating a lively pattern of bright and dark areas that accentuate the blue saturation and create a sense of motion as the gem moves. For a client who treasures living color and a natural, luxurious look, rather than prioritizing white light fire alone, this sapphire will usually outperform more common colorless gems in terms of character and presence.

If your need is an engagement ring that will be admired every day, or a rare piece to add to a collection, this sapphire answers both objectives with poise and authenticity. Being from Ceylon, it carries the lineage that many connoisseurs seek, known for producing lively, medium to intense blues that balance saturation with brilliance. The fact that this stone is unenhanced increases its rarity and long term collectibility, and The Natural Sapphire Company stands behind its provenance and quality. We can assist in choosing settings that amplify the pear shape and the mixed brilliant cut, for instance a minimal bezel to show off the outline while protecting the point, or a simple claw setting to maximize light exposure to the pavilion. Our goal is to match the gem to your personal priorities, whether you want maximum face up size, deepest color, or the most scintillation. Reach out and we will provide detailed images, viewing options, and design consultations, so that the search that brought you here truly does end with this exceptional Ceylon sapphire.
