1.38 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing presents one transparent round blue sapphire, weighing 1.38 carats, with precise dimensions of 6.41 by 6.41 by 4.38 millimeters, cut in a faceted mixed brilliant style, and finished with an excellent polish. The clarity has been evaluated at eye level as very very slightly included, indicating that inclusions are minor and do not detract from the gem's visual performance under normal viewing. The stone has undergone heat treatment, a common and stable enhancement applied to improve color and clarity, and its origin is Ceylon, Sri Lanka. At The Natural Sapphire Company we document these technical attributes to provide an accurate basis for assessment, and the combination of weight, dimensions, and cutting style gives a balanced face up presence suitable for a variety of mounting options.

The color of this sapphire is notable for its rich, bold character, a deep blue with intense saturation that reads clearly and confidently in hand. This depth of color functions visually as a symbol of personal power and distinction, offering a presence that is both refined and assertive without the need for embellishment. The intense color intensity reported for this stone manifests as strong saturation and consistent tone across the table, which allows the gem to maintain vividness even when viewed in different lighting conditions. For collectors and connoisseurs who associate color with expressive value, this sapphire conveys a considered statement, one that communicates authority through quality rather than volume.

The mixed brilliant cut employed here is designed to optimise both scintillation and color delivery, combining angled pavilion facets that deepen hue with a faceted crown that returns light to the viewer. The measured depth of 4.38 millimeters relative to a 6.41 millimeter diameter yields an overall depth proportion of approximately 68.3 percent, a geometry that contributes to the stone's saturated appearance while still permitting lively internal reflections. The excellent polish enhances facet definition and surface brightness, ensuring that the stone exhibits crisp facet junctions and clean light return. With a clarity grade of very very slightly included at eye level, the internal features are minimal and typically inconspicuous in mounted settings, allowing the gem to present a clean, uninterrupted color face up.

From a practical perspective, this Ceylon sapphire is durable and suitable for everyday wear when set appropriately, reflecting the inherent toughness of corundum. Heat treatment applied to the stone is considered stable and permanent under normal wearing conditions, and routine care consists of gentle cleaning with warm water, mild detergent, and a soft brush, avoiding harsh chemicals and extreme thermal shock. For mounting, settings that protect the girdle and pavilion while allowing sufficient light through the crown will best showcase the intense blue and the mixed brilliant faceting. At The Natural Sapphire Company we recommend that buyers seek accompanying documentation and consider professional setting services to maximise both protection and visual impact. This sapphire offers a precise combination of color, cut, and clarity that aligns with discerning standards for a gemstone intended to symbolize personal authority and refined distinction.
