0.64 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Allow me to present a jewel of singular refinement, a 0.64 carat round blue sapphire that embodies both classical elegance and contemporary desirability. This gem measures 4.95 x 4.89 x 3.38 mm and carries a mixed brilliant cut that has been executed with precision to maximize both fire and color. The transparency of the stone is immediately striking, with a clarity graded as very slightly included when viewed at eye level, which gives the gem a sense of depth and authenticity without distracting surface imperfections. Its vivid color intensity captures a deep Ceylon blue that glows from within, and with excellent polish every facet reaches out to the light with a mirror like clarity. This sapphire has been gently heat treated, a widely accepted enhancement that refines its tone and stability, and its origin is Ceylon Sri Lanka, a region that has supplied the world with some of the most celebrated sapphires in history.

In tone and presence this stone invites comparison to legendary sapphires that have graced crowns and museum displays, while remaining uniquely wearable and personal. Think of the cornflower depth that made the Logan Sapphire a symbol of refined taste, and the luminous saturation that has defined centuries of Ceylon stones prized by royalty. Though modest in size compared to those famed examples, this 0.64 carat sapphire channels the same regal blue that has been sought by collectors for generations. Its vivid color intensity recalls the rich blues that once rivaled the glamour of Kashmir sapphires in their heyday, while its clarity and polish echo the standards applied to museum quality gems. The comparison is not to suggest parity in scale, but rather to highlight how this gem concentrates historical virtues into a gem that can be carried comfortably, worn daily, and cherished intimately.

From a gemological and design perspective this sapphire offers advantages that are rare at this price point and size. The round shape and mixed brilliant cut create a harmonious balance between scintillation and color saturation, so the stone flashes bright white brilliance across the table and crown facets while retaining a saturated blue body color when seen face up. The proportions, at 4.95 x 4.89 x 3.38 mm, are exceptionally well judged to ensure the stone sits with poise in a fine mounting, whether set as the centerpiece of a delicate solitaire, as the heart of a trilogy ring, or as an element in a bespoke pendant. The very slightly included clarity grade means that the stone reads clean to the eye, preserving the illusion of purity that discerning clients expect, yet it retains natural character under magnification that connoisseurs appreciate. Heat treatment has been applied in the controlled manner recognized by experts to enhance color while maintaining structural integrity, and the excellent polish speaks to the skill of the lapidary who brought this Ceylon crystal to life.

Owning this sapphire from The Natural Sapphire Company is an assertion of cultivated taste, a decision that aligns the wearer with a tradition of elegance that spans continents and centuries.
