0.43 Ct. Blue Sapphire from Ceylon (Sri Lanka)

If you are searching for a refined, authentic Sri Lankan sapphire that brings quiet elegance to an engagement ring or a bespoke collector piece, this transparent 0.43 carat emerald cut blue sapphire from Ceylon is a perfect solution. At 5.91 by 3.12 by 1.94 millimeters it is a beautifully proportioned stone that suits delicate, modern settings as well as vintage inspired designs. The stone shows a medium light cornflower blue that reads soft and luminous on the finger, its step cut facets producing a serene hall of mirrors effect. Clarity is very very slightly included when evaluated at eye level, the polish is excellent, and importantly this sapphire is unenhanced, confirming the natural beauty and stability of its color and character. At The Natural Sapphire Company we source such unheated Ceylon stones because clients seeking a truthful, enduring gemstone often tell us they want the confidence of natural origin and minimal intervention.

For customers imagining this sapphire in a custom piece, the emerald cut shape opens many design possibilities that highlight its clean geometry and distinctive blue tone. For a timeless engagement ring, set it east west in a slim platinum band with two tapered baguette diamonds flanking each end, the step cuts mirroring one another for a sleek, architectural profile. If you prefer a more radiant contrast, a halo of small round brilliant white diamonds will add sparkle without overpowering the stone, or a pair of delicate pink sapphires on the shoulders will create a romantic, modern palette that brings out the sapphire’s subtle warmth. For a vintage look, a milgrain bezel in 18 karat yellow gold will warm the blue and emphasize the stone’s rectangular silhouette, while a bezel in rose gold paired with small rose cut diamonds gives a softer, antique inspired glow.

Beyond rings, this sapphire adapts beautifully to pendants and three stone bracelets, where its elongated shape can be echoed by baguette or bar set accents to create a refined line of color. Collectors will appreciate the unheated Ceylon origin and the excellent polish, attributes that make it a rare and wearable treasure.
