0.90 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Beneath the green canopy of Sri Lankan hills, where rivers cut through ancient rock, this sapphire began a patient journey that spans geological time and human care. Born in the storied gem fields of Ceylon, this transparent blue sapphire carries the quiet authority of its island origin, an intense color that reads as deep ocean at midday. We at The Natural Sapphire Company imagine the stone when it was first unearthed, still rough, its potential hidden in a matte crust of host rock, waiting for hands that could translate that promise into a jewel. We present one beautiful 0.90 carat oval sapphire, its dimensions measured precisely at 6.23 x 5.03 x 3.54 mm, a shape that honors the natural outline of the crystal while inviting the eye with classic, wearable proportions. The mixed brilliant cut gives the gem a modern geometry in the crown, paired with carefully faceted pavilion planes, a combination that deepens the hue and lends a lively internal fire. The polish is excellent, a mirror like finish that allows light to glide across each facet, and the overall presence of the gem is both elegant and commanding.

When describing a gemstone to someone who will carry it through many moments, inclusions are not imperfections to hide, they are unique identifiers that make the stone a singular companion. Evaluated at eye level this sapphire is eye clean, meaning the loupe free profile is clear and open, yet under magnification a gemologist will note tiny traces that tell stories. Slender silk like needles, gentle color zoning from the crystal growth, and occasional minute mineral crystals sit like bookmarks inside the stone, evidence of the conditions that conspired to create this blue. These internal features act as a fingerprint, they confirm the natural formation in a specific geological environment, they speak to the path from molten or metamorphosed material to a gem quality crystal. Rather than detract, these inclusions endow the sapphire with texture and authenticity, they give it a living depth that no synthetic or perfectly dead copy can replicate. To the trained eye and to the attentive wearer, such inclusions are cherished notes in a composed score, each telling when the crystal paused and when it accelerated in growth, each indicating the unique moments buried within.

The transformation from rough to this polished gem is both science and craft, a process guided by the lapidary to preserve color and weight while unlocking brilliance. Heat treatment has been applied, a widely accepted and stable enhancement that intensifies the blue and harmonizes tone, revealing the vivid personality that so many collectors and brides seek. This enhancement is disclosed, and the heat treatment was executed in controlled conditions to enhance the natural color without masking the stone origin. The choice of a mixed brilliant cut was deliberate, it maximizes face up color while allowing for flashes of white light from the crown facets, a balance that makes the gem sing on the finger. The dimensions 6.23 x 5.03 x 3.54 mm give the stone a well proportioned depth to carry its 0.90 carat weight, and the excellent polish ensures smooth facets and crisp reflections. Consider how this oval sits in a setting that either embraces its classic silhouette in a simple solitaire, or lifts its color with a delicate halo, perhaps in warm metal to add contrast, perhaps in platinum to keep the blue pure and cool. We share images of the sapphire on a hand so you can imagine scale, and we encourage clients to picture the gem catching light from day to evening.

At The Natural Sapphire Company we believe provenance, transparency, and craft matter as much as beauty, and this Ceylon sapphire brings all three.
