67.93 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

From the riverbeds of Ceylon, where monsoon rains carve ancient channels through gem country, this blue star sapphire began its journey as a rough crystal buried beneath layers of alluvial soil. Artisanal miners in Sri Lanka, guided by generations of local knowledge, discovered the stone and recognized its potential. Handled with care, the rough was sent to master cutters in Ratnapura, where the cabochon was shaped to a refined oval measuring 21.95 by 16.16 by 16.04 millimeters, and brought to a remarkable weight of 67.93 carats. At The Natural Sapphire Company we honor that lineage of craft, selecting only pieces that reveal their story through form and light. This gem is completely natural, with no enhancement, and its medium blue tone carries the cool depth that Ceylon sapphires are celebrated for. Slight inclusions, visible at eye level, trace the silk of rutile that creates the six ray star, a feature cherished through centuries in Asian and Western cultures alike, a stone that once graced sovereigns and was long held as a talisman for protection and insight.

Under the loupe and in natural light, the excellent polish and translucency of this cabochon present a luminous surface that allows the star to glide across the dome with graceful uniformity. From every angle the asterism reads as an emblem of precision, the intersecting rays crisp and centered when the stone is oriented to light, giving an impression of flawless radiance even as the internal silk that produces the star remains a testament to natures complexity. The slightly included clarity actually enhances the gems character, scattering light in soft bands and deepening the blue, while the superb polish creates a mirror smooth finish that amplifies reflections and visual depth. Wearers will feel the history under their fingertips, a storied gem that combines geological time, human skill, and cultural resonance into a single, luminous object. At The Natural Sapphire Company we present this Ceylon star sapphire as both a collector piece and a wearable artifact, a rare example of natural asterism, honest origin, and masterful cutting, ready to be set and to continue its journey with you.
