0.44 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This beautifully transparent blue sapphire weighs 0.44 carat and presents in a classic round shape, with precise dimensions of 4.74 by 4.75 by 2.58 millimeters. Cut as a mixed brilliant, this gem benefits from a combination of facets designed to maximize both scintillation and color saturation. Its clarity is graded as very slightly included, evaluated at eye level, which means inclusions are minimal and rarely perceptible to the unaided eye. The color intensity is described as intense, and the polish is excellent, producing a lively, glassy face up that interacts attractively with ambient light. Importantly for discerning buyers, this sapphire has no enhancement, and its origin is Ceylon, Sri Lanka, a source long prized for producing some of the world s most desirable blue corundum. The Natural Sapphire Company is pleased to offer this untreated Ceylon sapphire to customers looking for a natural, high quality specimen.

The Ceylon origin contributes materially to the gem s appeal, since Sri Lanka is renowned for sapphires that combine clarity with a lively, vibrant blue that can show slight violet undertones under certain light. Intense color intensity in a Ceylon sapphire often translates to a vivid, lively face up that reads as bright and saturated without appearing overly dark, which is particularly attractive for wearable jewelry. The mixed brilliant cut enhances these properties by directing light into the crown for scintillation, while preserving the depth necessary to display saturated color. The stone s proportions yield a depth of approximately fifty four percent, a proportion that balances weight retention with optimal light return, producing an attractive visual diameter for its carat weight. Excellent polish ensures that the facets meet crisply, providing clean reflections and maximizing the gem s overall brilliance and fire.

Clarity and treatment status are central considerations for educated buyers, and in this example the very slightly included grade at eye level signals a stone that is effectively eye clean for most viewers, yet still natural in its formation. Such inclusions do not materially impair transparency or brilliance, and they confirm the natural character of the gem. The absence of enhancement, especially heat treatment or diffusion, substantially increases this sapphire s rarity and market desirability, because most commercial sapphires are heat treated to improve color and clarity. An untreated Ceylon sapphire with intense color, excellent polish, and minimal eye level inclusions represents a convergence of attributes collectors and connoisseurs prize, since it offers both aesthetic excellence and geological authenticity. The mixed brilliant design also helps to mask small inclusions while amplifying sparkle, making the stone attractive in a variety of settings.

Durability is another critical factor for practical ownership, and corundum, the mineral family that includes sapphires and rubies, ranks nine on the Mohs scale of hardness, second only to diamond at ten. This means a sapphire is significantly more resistant to scratching than common jewelry materials such as quartz, topaz, and many forms of glass, and it is well suited to everyday wear, including rings and bracelets, when set and treated with reasonable care. Corundum lacks the perfect cleavage seen in some other gemstones, which enhances toughness, but like all gemstones it can chip or fracture if subjected to a sharp blow, especially at facet junctions or along thin edges. For longevity, protective settings such as secure prongs or a bezel are advisable for active wearers, and cleaning with warm soapy water and a soft brush will maintain brilliance without risk.
