5.26 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This is a superb, transparent blue sapphire that stands apart from many of the stones commonly offered on the market, and it arrives with GIA certification to verify every important detail. The gem is a 5.26 carat cushion shape sapphire, with precise dimensions of 10.13 by 8.66 by 6.55 millimeters, a mixed brilliant cut, a clarity grade described as very very slightly included at the eye level, intense color intensity, and an excellent polish. Importantly, the stone is unheated and originates from Ceylon in Sri Lanka, a designation that carries a particular cachet among collectors and connoisseurs because natural, untreated sapphires from this source are far less common than heat treated material. When compared to the many heated or lab created alternatives in the marketplace, this sapphire offers proven natural origin and confirmed absence of enhancement, attributes that preserve rarity and long term value, while delivering an immediate visual impact through its vivid blue tone and transparent clarity.

From a design and setting perspective this cushion shape mixed brilliant cut is exceptionally versatile, and it outperforms many other forms when the goal is both brilliance and depth of color. The mixed brilliant approach gives the pavilion faceting dynamic light return and scintillation, producing flashes that are more lively than those seen in step cut or strictly vintage cushion stones. The generous table and deep pavilion proportions in this particular example balance color and sparkle in a way that reduces the washed out look some oversized tables can produce, and that also maintains face up color saturation without sacrificing brilliance. Compared to sapphires from different origins, this Ceylon gem displays a lively, electric blue that is brighter than many heated stones from other locations, and cleaner at face up viewing than typical material at similar carat weights. Because the clarity reads very very slightly included at the eye level, the stone offers the clean, luxurious presentation buyers expect in high end jewelry, while retaining the natural inclusions that confirm authenticity to a trained eye.

The customization potential for this sapphire is wide ranging, and it adapts beautifully to multiple jewelry styles, which makes it ideal for buyers who want a single center stone that can be reimagined in many ways. For a classic engagement ring, a four or six prong solitaire in platinum or 18 karat white gold will showcase the cushion outline and let the mixed brilliant cut sparkle, while a delicate diamond halo will enhance perceived size and intensify the perceived blue through contrast. For a vintage inspired look, a bezel with a milgrain edge will protect the cushion corners and give the piece a timeless character. For everyday wear, a low profile bezel or a secure cathedral setting will reduce snagging while preserving light return through a raised gallery. For modern statements, an east west orientation, a tension style mount, or an open half bezel with visible prongs can create contemporary lines that emphasize the stone geometry. This sapphire is also an excellent choice for a pendant because the depth will give it presence and the high polish will provide remarkable face up brilliance. For men seeking a distinctive signet or a bold cocktail ring, the cushion shape reads elegant and masculine without appearing oversized, and the 5.26 carat weight provides a strong presence on the hand without becoming cumbersome.

Beyond single piece considerations, this sapphire performs well as the focal point in multi stone compositions, and it offers superior value relative to similar sized stones that have been treated or synthesized. A three stone ring with tapered baguette diamonds will create a clean, architectural profile, while paired side sapphires in complementary tones will produce color narratives that are rare in mass market pieces. Combining this Ceylon blue sapphire with green tsavorites or warm yellow diamonds will produce striking color contrasts that are difficult to replicate with treated material, because the unheated stone maintains color behavior under varied lighting that collectors prize. From a technical point of view, the sapphire is durable for regular wear due to its inherent hardness, and the excellent polish ensures that every millimeter of metalwork will interact attractively with the gem surface. When customers compare this offering from The Natural Sapphire Company to similar items elsewhere, they should consider the premium that labs like GIA place on verified origin and no enhancement, and how that premium is reflected in secondary market liquidity and long term appreciation.

At The Natural Sapphire Company we assist clients through every stage of customization, from initial consultation and design proposals, to CAD renderings and wax proofs, and finally to careful hand setting and finishing. We recommend conservative approaches to any recutting since preserving carat weight while optimizing table proportions and pavilion angles often yields greater final value than aggressive trimming. For setting recommendations we suggest protective prongs or bezels for active lifestyles, and raised galleries or open head settings for designs that emphasize light entry. Our workshop can coordinate diamond accents that are proportioned to the 10.13 by 8.66 millimeter top view, and we can propose metal choices that will either cool the blue with white metals or warm it with yellow or rose gold for a vintage appearance. Every bespoke project with this sapphire includes a review of the GIA report so that clients can make informed decisions about facet orientation and stone alignment relative to finger anatomy or necklace bail position. If you are looking for a natural, visually striking, and ethically sourced center stone that outshines standard market alternatives in natural authenticity and flexibility of design, this unheated 5.26 carat Ceylon cushion sapphire from The Natural Sapphire Company is a rare opportunity, and we welcome inquiries to explore how it can be turned into a custom piece that will be treasured for generations.
