0.81 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for the perfect stone to complete an engagement ring, or when your collection is missing a sapphire with true personality, this 0.81 carat pear shaped blue sapphire from The Natural Sapphire Company answers that search with quiet confidence. Its pear silhouette measures 7.28 by 5.11 by 2.96 millimeters, a versatile size that sits elegantly on the hand while offering enough presence to be the focal point of a ring. The intense blue color is clear and compelling, the clarity grade is very very slightly included evaluated at eye level, and the gem benefits from an excellent polish and a skilled mixed brilliant cut. Originating from Ceylon Sri Lanka, a source renowned for its velvety cornflower to violet blue sapphires, this gem has been heat treated, a standard enhancement that stabilizes and deepens the tone while preserving the natural character that collectors and lovers of fine jewelry prize.

The sapphire’s internal structure, its corundum crystal lattice, is the secret behind the deep, lively sparkle that sets it apart. Corundum is a trigonal crystal, composed of tightly bound aluminum and oxygen ions, and this ordered structure produces a relatively high refractive index that invites light to enter the stone and dance across its interior. Unlike diamonds, which owe much of their fire to dispersion, sapphires rely on a combination of refractive power and pleochroism, the property that allows them to show slightly different hues when viewed from different angles. The mixed brilliant cut on this pear shaped sapphire has been designed to exploit those characteristics, balancing a faceted crown that scatters light with a pavilion cut to return that light toward the viewer. The result is a mix of lively scintillation and a rich, saturated body color, a sparkle that feels both energetic and refined, especially when the excellent polish allows every facet to mirror light crisply.

Clarity and treatment are often decisive when choosing a gemstone for daily wear or for an heirloom piece, and this gem performs beautifully on both counts. Being very very slightly included evaluated at eye level means that under normal viewing its interior reads as clean, and the tiny inclusions that do exist serve to identify the natural origin rather than distract from the gem’s brilliance. The heat treatment has been applied thoughtfully, enhancing the blue tone and reducing silk or rutile that would otherwise veil the stone. Because the polish is excellent, facet junctions are sharp and smooth, maximizing light return and creating the kind of lively face up appearance that looks exceptional in any setting. The sapphire’s natural toughness, second only to diamond on the Mohs scale, makes it an ideal candidate for an engagement ring that will be worn every day, and a thoughtful setting that gives the point of the pear a protective shoulder will preserve its integrity while letting the top facets do the work of dazzling.

If your aim is to stop searching and to invest in a sapphire that fulfills both aesthetic and practical needs, this Ceylon pear from The Natural Sapphire Company is a complete solution. Its size and proportions make it equally suitable for a solitaire engagement ring, a halo composition that amplifies sparkle, or a bespoke collector piece that emphasizes color and cut. We stand behind the provenance and the treatment disclosure of every gem we offer, and we are happy to advise on mounting styles that will maximize its light performance while protecting the stone. For someone who wants a sapphire that sparkles with structural depth rather than mere surface flash, this intense blue, mixed brilliant cut pear shape embodies that balance, promising emotional impact, day to day wearability, and the kind of refined, natural beauty that ends a search and begins a lifetime of admiration.
