1.87 Ct. Blue Sapphire from Thailand

This 1.87 carat oval sapphire is a rare offering from The Natural Sapphire Company, presented in a tone of quiet luxury that will appeal to collectors who understand the power of provenance and exceptional craftsmanship. Faceted into an elegant oval measuring 7.86 x 6.07 x 4.09 mm, this gem has been classified Other certified Blue Royal Blue, and it carries the deep, resolute presence of a genuinely dark blue stone. Its heat treated enhancement reflects a long established method used to refine and stabilize color, and its origin in Thailand speaks to a storied tradition of fine sapphire cutting and careful selection. The combination of a meaningful weight just under two carats, a refined oval silhouette, and an eminently wearable size makes this sapphire an ideal centerpiece for a personal heirloom or a bespoke commission, reserved for those who prefer rarity over ubiquity.

The mixed brilliant cut of this sapphire is the defining element of how it speaks with light, and the cutter has balanced a series of well considered facet planes to bring forward the gem’s natural luminosity. The crown facets have been arranged to gather and disperse light into intense flashes, while the pavilion facets act as a precise mirror, returning light through the table in a controlled way that enhances perceived depth. This cut style merges the scintillation of a brilliant pattern with the elegant face up color retention that an oval silhouette provides, resulting in lively, crisp reflections that animate the gem with movement. Because the stone carries dark color intensity, the mixed brilliant cut mitigates the risk of a murky appearance by creating areas of bright, concentrated reflection against velvety blue planes, giving the eye points of brilliance that contrast beautifully with the richer body color. Excellent polish across every facet plane ensures minimal light leakage at the surface, so that each tilt produces a fresh ballet of highlights, a captivating interplay that rewards both close inspection and the casual glance.

Clarity has been graded as slightly included when observed at eye level, and the thoughtful cutting strategy here uses facet arrangement, depth control, and polish to integrate those natural characteristics into the stone’s overall beauty. Rather than attempting to hide inclusions, the cutter has accentuated the sapphire’s best optical qualities so that any internal features sit discreetly, often masked by the stone’s structured play of light. The 4.09 mm depth is calibrated to preserve weight while maintaining optimal light return, and within this proportion the mixed brilliant design maximizes brilliance without sacrificing the saturated Royal Blue tone that defines this piece. In practical terms this means a gem that reads rich and substantial when worn on the finger or at the throat, yet displays flashes of life that prevent the color from appearing flat. Such harmony between cut and material is the hallmark of stones chosen for discerning collectors, and it is precisely the kind of considered gem that The Natural Sapphire Company curates for clients seeking something both distinctive and wearable.

This sapphire is offered as a single, limited opportunity to own a stone that combines provenance, skilled cutting, and a depth of color not commonly available at this size. We present it as ready to be set in a bespoke design, where a custom mounting can further enhance how light meets metal and returns through the table to maximize contrast and brilliance. Owning this sapphire means belonging to a select group who appreciate the quiet confidence of a Royal Blue gem, carefully finished with excellent polish and professionally heat treated in a tradition rooted in Thailand. If you wish to explore mounting options, request detailed light performance images, or secure this stone for a private commission, The Natural Sapphire Company will guide you through every step with the personal attention and expertise this gemstone deserves, assuring discretion, certification, and an experience that honors the rarity of the piece.
