0.63 Ct. Blue Sapphire from Ceylon (Sri Lanka)

There is a long and storied human relationship with the blue sapphire, and this 0.63 carat round gem is a small but luminous chapter in that continuing history. From the ancient courts of Asia to the coronets of European royalty, sapphires have been prized for their depth of color and their ability to convey constancy and reverence through generations. This particular stone comes from Ceylon, Sri Lanka, a place whose name has been synonymous with exceptional blue sapphires for centuries, and it carries with it that legacy of maritime trade routes, skilled lapidaries, and reverence for natural beauty. The Natural Sapphire Company presents this transparent round sapphire with full respect for that lineage, offering a gem that is at once historical in spirit and perfectly suited to modern jewellery. At 0.63 carats with exact dimensions of 5.06 x 4.97 x 3.18 mm, it sits in a size that is versatile and elegant, large enough to command attention while maintaining the intimate scale that appeals to traditional tastes.

What defines this sapphire beyond its origin and weight is the artistry of its mixed brilliant cut and the precise geometric faceting that allows maximum light play. The mixed brilliant design blends the classical round silhouette with an arrangement of crown and pavilion facets engineered to reflect and refract light in dynamic ways, creating a dance of bright flashes and deep velvety blue windowing. The crown facets draw light into the stone and the pavilion facets return it with intensity, producing scintillation that is especially lively when the gem is set into a ring and encounters the subtle movements of the hand. Because the stone is transparent and carries a vivid color intensity, each facet becomes a stage for color and light to interact, showing a range of blues from vivid cornflower tones to deeper royal hues as viewing angles and lighting change. The polish on this stone is excellent, which means facet junctions are crisp and mirror like, further improving the stone's ability to return light to the eye with uncompromised brightness. The clarity grade is described as very very slightly included as evaluated at eye level, a mark of exceptional clarity that allows the color and faceting geometry to remain the primary focus, without distraction from visible inclusions.

Beyond the technical virtues of cut, clarity, and polish, there is a quiet timelessness in how this sapphire will wear and age in an heirloom setting, a quality that will appeal to anyone who honors tradition and seeks to create a legacy piece. Heat treatment has been applied to this stone, a widely accepted and stable enhancement that brings forward the vivid color for which Ceylon sapphires are celebrated, while preserving natural character and durability. The mixed brilliant faceting is ideal for classical settings, including solitaire designs that emphasize the round form, three stone compositions that celebrate continuity, and vintage inspired settings where symmetry and geometry complement ornate metalwork. On the finger this stone reads as poised and dignified, its near perfect round proportions and balanced depth creating a focal point that is both noble and approachable. The geometry of the faceting means that the gem performs across a variety of light conditions, from the soft, diffuse illumination of an overcast day to the crisp highlights of evening LED, always returning color and life with a measured, assured brilliance.

At The Natural Sapphire Company we understand that selecting a gem is as much about personal narrative as it is about quality metrics, and this Ceylon round sapphire speaks to those who value continuity, refined taste, and the reassuring presence of a stone that will endure. Its vivid blue tone, its mixed brilliant geometry, its excellent polish, and its very very slightly included clarity as evaluated at eye level all combine to offer a jewel that is immediately beautiful and destined to become more meaningful with years of wear. Whether you are seeking an engagement center that references classical ideals, a gift to honor a milestone, or the beginning of a family heirloom, this sapphire offers a connection to the past while performing with precise optical modernity. We welcome you to discuss settings, mounting options, and bespoke designs with our team, and to consider how this gem might be set to carry forward the traditions and stories that matter most to you.
