1.51 Ct. Green Sapphire from Ceylon (Sri Lanka)

In the rarefied world of collectors and connoisseurs a single stone can transform a collection into a legacy. This is one such stone from The Natural Sapphire Company, a 1.51 carat green sapphire of transparent clarity that reads like a private discovery. Sourced from the storied mines of Ceylon Sri Lanka, this gem measures 7.19 by 5.33 by 3.58 millimeters, and arrives to you in an emerald cut shape with an intense green saturation and an excellent polish. Its clarity grade is very very slightly included evaluated at eye level, a degree of purity that allows the color to breathe and the facets to speak with certainty. The stone has been heat treated to bring forward the depth and warmth of its hue in a stable and predictable manner, a judicious enhancement that respects the integrity of the material while elevating its visual presence. When you consider that each gem of this caliber and provenance is unearthed in very limited quantities you begin to understand how ownership of this sapphire confers immediate access to a select circle of collectors who appreciate true rarity.

The geometry of this emerald cut is where restraint becomes drama. The stone has been cut with a disciplined series of step facets across the crown and pavilion that create wide luminous planes and a hall of mirrors effect, producing broad flashes of color rather than the scattered scintillation of a brilliant cut. The proportions of 7.19 by 5.33 millimeters yield a pleasing elongation that flatters ring settings and bespoke designs alike, while the 3.58 millimeter depth has been calibrated to maximize internal reflection without sacrificing the open window of color that collectors prize in step cuts. Every facet junction is crisp thanks to an excellent polish, so light enters the crown travels through the heart of the stone and returns as deep green flashes and subtle sheens, depending on the angle of the eye and the quality of light. What the emerald cut does so beautifully for this green sapphire is to control light in a way that highlights both tone and transparency, creating moments where the gem appears to glow from within and other moments where its geometric planes announce themselves with architectural clarity.

Color and clarity exist here in a harmonious balance, making the stone feel both intimate and monumental. The intense color intensity of this Ceylon green sapphire reads as an elegant green that shifts slightly across different lighting conditions, revealing cooler forest notes in shaded environments and a richer bottle green in warmer light. The very very slightly included clarity evaluated at eye level means that to the unaided eye the gem reads as clean and pristine, allowing uninterrupted appreciation of its hue and the purposeful interplay of its step facets. Heat treatment has been applied to stabilize and enhance the color, a common and accepted practice that ensures your investment will maintain its visual strength through wear. Because the cut emphasizes color over sparkle the gem rewards close inspection and considered mounting, it invites a setting that lets the geometry breathe and the light perform, whether that setting is a discreet bezel that honors the stone s lines or a bespoke open prong that lets the crown converse directly with daylight.

Owning this sapphire is an invitation to join a small group of collectors who prefer the silent authority of form and depth to loud display. At The Natural Sapphire Company we curate such pieces with an eye toward provenance and individuality, and we offer a bespoke design service to help translate this gem s geometry into an heirloom. Picture this 1.51 carat emerald cut green sapphire set into a refined ring that echoes its rectangular proportions, or let it sit within a minimalist pendant that frames its step facets like a private gallery window. We can provide full documentation about origin treatment and exact measurements and we will consult with our master setters to propose mounting options that protect and showcase the stone while honoring its Ceylon heritage. Because stones of this nature are singular by definition we recommend prompt consultation for those who feel the quiet pull of ownership, and we are pleased to offer private viewing appointments and secure delivery for collectors who require discretion. To own this gem is to hold a restrained but unmistakable statement of good taste, a rare geometry of light and color that will not simply be worn but quietly celebrated for generations.
