4.55 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

This remarkable blue sapphire from The Natural Sapphire Company weighs 4.55 carats, and is fashioned into a graceful cushion shape with dimensions of 9.77 x 8.14 x 6.27 mm, and it immediately commands attention with its sugar loaf cut and translucent body. The sugar loaf cut gives the gem a generous domed profile that reads as both classic and contemporary, allowing the vivid color intensity to play across the surface with a deep, even saturation. Evaluated at eye level the clarity grade is very slightly included, which means the stone presents as clean to the naked eye while retaining natural character when viewed by a trained eye. The excellent polish enhances the sapphire surface, producing a lively, glassy finish that draws the eye, and the heat treated enhancement is a stable, standard practice that has optimized the stone color while retaining full integrity in the crystal structure.

Origin adds personality to any sapphire, and this stone hails from Ceylon Sri Lanka, a region celebrated for producing sapphires with lively, velvety blue hues and exceptional depth. Ceylon sapphires are known for their bright and vivid tones, and this example displays that signature intensity, a vivid blue that is deep yet not overly dark, offering remarkable presence in lighter settings and strong presence in more dramatic designs. The sugar loaf cushion shape measures generously for its weight, and the domed table plays up the saturation, creating flashes of electric blue at different angles. The natural inclusions contribute to the gem story, confirming its natural origin while not distracting from its beauty, and the overall translucency provides a luminous internal glow that complements both antique inspired and modern settings.

In practical terms this sapphire is versatile and durable for fine jewelry, suitable for a statement ring, a pendant, or a bespoke bracelet center, and its 4.55 carat size offers genuine presence without overwhelming delicate designs. The vivid blue will pair beautifully with platinum for a cool modern look, with white gold to keep the palette classic and refined, and with yellow gold for a high contrast vintage inspired style that underscores warmth and richness. For a halo design, modest diamonds will accentuate the vivid blue without competing, while baguette accents will provide an elegant architectural frame. Because the gem is heat treated, the enhancement is considered permanent and stable under normal wear, and standard precautions such as avoiding harsh chemicals and extreme heat are recommended to preserve the polish and mounting integrity.
