3.59 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This C.Dunaigre certified blue sapphire offered by The Natural Sapphire Company is a striking example of classic Ceylon color, weighing 3.59 carats, with measurements of 10.55 by 7.84 by 5.13 millimeters, presented in an elegant oval shape. The gem has been fashioned with a mixed brilliant cut that combines the scintillation of brilliant facets with the depth control of step cutting, producing lively sparkle without sacrificing the saturated color that collectors seek. The color intensity is described as vivid, delivering a pure, medium to deep cornflower to royal blue that is typically associated with fine Sri Lankan sapphires. An excellent polish enhances surface reflection and visual clarity, allowing light to enter and return from the pavilion with minimal obstruction, creating the kind of brilliance that reads well in photographs and in hand.

From a gemological standpoint this sapphire is noteworthy for its clarity grade of very very slightly included when evaluated at eye level, a level of clarity that is uncommon in stones of this size and color. Eye level evaluation means the gem was examined without magnification, and the very very slight inclusions present do not interfere with transparency or color saturation, they function as natural identifiers rather than detractors. The stone has undergone heat treatment, a standard and stable enhancement in the sapphire trade, applied to improve tone and to dissolve minor inclusions without compromising structural integrity. The origin is Ceylon Sri Lanka, a source with a centuries long reputation for producing sapphires with lively cornflower hues and a slightly lighter, more velvety blue than some other localities, a characteristic that appeals to buyers who value both history and aesthetic nuance. The accompanying C.Dunaigre report provides independent verification of these attributes, supporting provenance and treatment disclosure.

For an educated buyer this sapphire represents both technical quality and practical versatility, qualities that make it an excellent choice for either daily wear or formal occasions. The corundum hardness of 9 on the Mohs scale offers exceptional durability for a center stone in a ring, while the 10.55 by 7.84 millimeter oval sits comfortably on most fingers, translating into a presence that is both impressive and wearable. The mixed brilliant cut is particularly forgiving in settings where maximum fire and brilliance are desired, allowing the stone to perform beautifully under various lighting conditions from office fluorescents to evening lamps. In terms of style the vivid blue reads equally well in a clean modern solitaire, a classic halo for added brilliance, or a more intricate vintage inspired setting, and it complements both white and yellow metals, making it adaptable to casual jeans and a blouse, or to a formal evening gown. At The Natural Sapphire Company we emphasize transparent certification, responsible sourcing, and expert cutting, and this sapphire embodies those priorities, making it a confident purchase for collectors and clients who seek a well documented, visually compelling, and enduring gemstone.
