1.17 Ct. Grey Star Sapphire from Ceylon (Sri Lanka)

This exceptional gemstone is a translucent grey star sapphire weighing 1.17 carat, cut into a classic oval form, with dimensions of 6.14 by 5.03 by 3.57 millimeters, and finished as a high dome cabochon to display a clean and focused star phenomenon. Our gemologists at The Natural Sapphire Company evaluated this stone and assigned a clarity grade of very slightly included when examined at eye level, which lends the gem a quietly natural character without distracting from its star, and the medium color intensity gives a sophisticated cool tone that shifts subtly with the light. The surface has been given an excellent polish, enhancing the silky luster that draws the eye to the centered asterism, and importantly this sapphire is natural and untreated, with no enhancement, coming to us from the storied gem fields of Ceylon Sri Lanka. The star is crisp and visibly centered under direct lighting, a hallmark of well formed rutile needle alignment within the corundum, and the overall translucency allows the star to float gently across the dome, creating an effect that is at once serene and magnetic.

Owning this star sapphire places you in a rarefied group of collectors and connoisseurs who prize natural asterism and provenance, because fine untreated star sapphires of this size and clarity are seldom available, especially from a Ceylon origin that is celebrated for both quality and historical significance. The Natural Sapphire Company brings you this single remarkable piece with a view toward exclusivity, each stone we select representing a limited opportunity, not a mass produced offering, and because untreated star sapphires of this nature are formed through unique geological conditions, there will not be another exactly like it. For those who appreciate the quiet authority of muted color combined with the theatricality of asterism, this gem is an objet d art, perfect for the collector who wants a statement that is understated and private, rather than loudly branded. We encourage thoughtful buyers to consider this stone as a bespoke centerpiece for a one of one creation, a jewel that will mark anniversaries, celebrations, and milestones with a singular presence that is both personal and rare.

When conceiving a setting for this grey star sapphire, consider metals and designs that respect the stone s natural dignity, because the medium color intensity sits beautifully against platinum, white gold, and palladium for a modern, cool palette, while a warm contrast in yellow gold can create an antique inspired aesthetic that makes the star read as moonlike and timeless. The cabochon height of 3.57 millimeters gives the star room to develop across the dome, so settings that allow the gem to be viewed from above preserve the visual drama, and a bezel setting with a finely finished edge will protect the rim while maintaining a refined silhouette, whereas subtle prong work can allow more light interaction and give a lighter, more open feel. For pendants consider a low profile mount that rests the dome close to the neckline so the star responds to ambient light, and for rings the balance between crown height and comfort is important, we recommend a thoughtful consultation with our design team to ensure the axis of the star is oriented for optimal display when worn. This stone also lends itself to cufflinks, brooches, and bespoke collar studs for those who seek singular accessories, each piece becoming a private emblem of taste.

We stand ready to assist you with provenance documentation, detailed imaging, and personalized service through The Natural Sapphire Company, our in house gemologists can provide further notes on the internal features and asterism under different lighting, and our design atelier is available to create a custom mounting that honors the gem s natural beauty. Because this sapphire is natural and unenhanced, simple care will preserve its condition, clean gently with warm water, mild soap, and a soft brush, avoid prolonged exposure to harsh chemicals and extreme heat, and store separately from harder or abrasive stones to protect the polished dome. Ownership of this star sapphire is an invitation to possess something seldom offered on the market, a quietly luminous treasure that will seldom be replicated, and for serious collectors and design minded clients alike this is an opportunity to commission a piece that will carry singular provenance. Please contact our sales team to arrange an exclusive viewing, we will tailor the experience to your needs, and guide you through secure purchase, bespoke design, and long term care, making certain that this rare Ceylon star sapphire finds its place in a collection that values rarity, authenticity, and timeless elegance.
