0.78 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional blue sapphire from The Natural Sapphire Company is a remarkably transparent and finely finished gemstone, weighing 0.78 carats, with precise dimensions of 5.67 by 5.67 by 3.38 millimeters. The gem is fashioned in a round shape with a mixed brilliant cut, a design that is engineered to present a dynamic interplay of color and light. At face up inspection the clarity is graded as very very slightly included, evaluated at eye level, which indicates that inclusions are minimal and do not interrupt the visual field to an unaided observer, preserving a clean and highly desirable appearance. The color intensity is vivid, a deep saturated blue that remains lively across different lighting conditions, and the polish is excellent, with sharp facet junctions and a smooth, reflective surface that enhances the stone presence. This sapphire has undergone controlled heat treatment, the industry standard enhancement for improving tone and clarity while remaining stable and permanent, and the material is traced to Ceylon Sri Lanka, an origin renowned for producing sapphires with pure, velvety blue hues.

From a gemological perspective the mixed brilliant cut on this sapphire is an advantageous choice because it balances maximum light return with concentrated color saturation, a quality that educated buyers will recognize as important for blue corundum. The cut combines the scintillation and fire characteristics of a brilliant facet arrangement on the crown with pavilion proportions that allow color to face up strongly, resulting in an appealing combination of sparkle and depth. The proportions of this stone yield an overall depth that is efficient at presenting the vivid blue without appearing overly dark, and the symmetry and polish enhance the optical performance by allowing crisp facet reflections and consistent light distribution. The clarity description of very very slightly included, evaluated at eye level, is significant because it communicates that while microscopic inclusions may be present, the gem appears clean to the eye, a factor that supports both aesthetic desirability and resale confidence. For collectors and connoisseurs who value accurate grading language, this specification reports what a practical, unaided viewing experience will be like, rather than relying solely on magnified assessments.

The Sri Lankan provenance of this sapphire contributes materially to its value profile and appeal, as sapphires from Ceylon Sri Lanka are historically associated with lively, vivid blues that often have a slightly lighter, more velvety character compared with examples from other localities. The trace elements responsible for blue color in corundum, principally iron and titanium, interact in Sri Lankan deposits in ways that frequently yield pleasing, evenly distributed color at relatively modest sizes, making a 0.78 carat vivid blue stone especially noteworthy. Heat treatment in sapphires from this region is a well understood and broadly accepted enhancement, typically applied to stabilize and enhance color and clarity, and when disclosed it is compatible with long term ownership and normal wear. For the informed buyer, the combination of natural origin, transparent body, vivid color, and disclosed heat treatment represents a transparent and ethical offering. The Natural Sapphire Company provides clear disclosure of all treatments and origin information, which is important for provenance documentation and for maintaining market trust.

This sapphire is versatile in practical use and style application, adapting seamlessly to both casual and formal settings without losing its presence. In a delicate everyday ring or stud earring design the 5.67 millimeter diameter is comfortable and elegant, offering a refined pop of color that complements daily attire while remaining substantial enough to be noticed. In a formal context the vivid blue will contrast beautifully against white diamonds or a halo setting, creating a classic statement piece suitable for evening wear or ceremonial occasions. The mixed brilliant cut and excellent polish mean the gem will animate well under both ambient daylight and artificial lighting, making it a dependable choice for mixed wardrobe use. For durability the stone should be set with conventional secure settings and checked periodically, and care is straightforward using warm water, a mild detergent, and a soft brush for cleaning, avoiding harsh chemicals or prolonged exposure to extreme heat. Whether purchased for an engagement, a bespoke jewelry commission, or as a collector specimen, this 0.78 carat Ceylon sapphire from The Natural Sapphire Company combines documented origin, professional finishing, and a vivid, clean appearance, offering both immediate aesthetic enjoyment and long term value for an educated buyer.
