3.55 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 3.55 carat blue sapphire from Ceylon, Sri Lanka, presents as an elegantly proportioned emerald cut measuring 9.18 by 7.93 by 4.81 mm, a profile that immediately signals refined craftsmanship and gemological quality. The stone displays vivid color intensity, a saturated yet pure blue that is characteristic of fine Ceylon material. Clarity is described as very very slightly included when evaluated at eye level, which means the sapphire reads as clean to the naked eye while retaining a natural internal character under magnification. The gem has an excellent polish, and it has been gently heat treated to enhance color uniformity and stability, an accepted and disclosed enhancement that improves overall aesthetic without compromising integrity. At 3.55 carats the sapphire is substantial enough to be the centerpiece of a sophisticated ring or pendant, while its measured proportions maintain an elegant table and pavilion depth that support both durability and presence.

The emerald cut was selected to maximize this sapphire’s innate optical strengths, rather than to mimic the scintillation of a brilliant cut. Its broad, parallel step facets and large open table create a hall of mirrors effect, producing broad flashes of color and a luminous depth that emphasizes the stone’s vivid blue rather than breaking it into small, scattered sparkles. This facet arrangement allows light to travel through the sapphire in clean planes, so color saturation and clarity are experienced directly and immediately, giving the gem a sense of depth and richness. The excellent polish ensures that facet junctions are crisp and reflective, optimizing light return and allowing the step facets to produce strong, even flashes of blue across the table and facets, while the pavilion angles preserve internal reflection to enhance perceived size and color intensity.

For the educated buyer, provenance, treatment disclosure, and cut geometry together determine lasting value. Ceylon origin is prized for its clarity and velvety blue tones, and the combination of very very slightly included clarity and excellent polish in this well cut emerald shape yields a stone that balances visual purity with natural origin. The heat treatment is disclosed and minor, consistent with trade standards to stabilize and enhance color. This sapphire from The Natural Sapphire Company offers a compelling, well documented example of classic Ceylon blue, ideal for collectors and connoisseurs seeking a substantial, transparent gem whose cut elevates its color and clarity in a timeless, wearable form.
