0.73 Ct. Blue Sapphire from Ceylon (Sri Lanka)

A rare opportunity awaits the discerning collector and bespoke jeweller, a single, beautiful transparent blue sapphire that embodies the quiet confidence of exclusive luxury. Offered by The Natural Sapphire Company, this gemstone is a 0.73 carat emerald cut shape sapphire, with precise dimensions of 6.08 x 4.06 x 2.86 mm, each measurement confirming its ideal proportion for refined custom jewellery. The emerald cut imparts a lengthened silhouette and architectural grace that is unusually elegant in a stone of this weight, creating the impression of a larger table and a stronger presence on the hand or at the throat. With its dark color intensity and excellent polish, this Ceylon sapphire reads as both classic and modern, a piece that belongs in an atelier and in the private collection of someone who understands rarity and refined taste. Availability is limited, and because The Natural Sapphire Company selects only the most distinctive stones for bespoke commissions, this example will appeal to an elite few who prize provenance, character, and enduring beauty.

Examined by experienced gemologists, this sapphire carries a clarity grade described as very slightly included, evaluated at eye level, which ensures that the gem remains visually clean and luminous while retaining individuality and natural origin. The emerald cut, with its large flat table and stepped facets, highlights this clarity and allows the eye to travel through the stone, appreciating internal structure and depth of color. The dark color intensity anchors the sapphire in a deep, velvety blue that reads as sophisticated and dramatic, ideal for settings that aim for presence rather than subtlety. Heat treatment, a stable and widely accepted enhancement, has been applied to bring out the most desirable hue while preserving the inherent natural qualities of the Ceylon origin. The excellent polish enhances facet definition and surface brilliance, giving the stone crisp reflections and a refined finish that will translate beautifully once set. These gemological attributes make this sapphire a superb candidate for a bespoke piece where the setting is designed to amplify every performing quality of the stone.

For custom design work, the dimensions and emerald cut shape of this 0.73 carat sapphire are particularly advantageous, because they lend themselves to a variety of design languages while maintaining graceful scale. In a single stone engagement ring the elongated profile will flatter the finger and can be oriented either lengthwise for a slimming effect or horizontally for a modern aesthetic. As the center of a three stone design, the emerald cut presents balanced symmetry with side stones such as tapered baguettes or shield cut diamonds, producing an architectural composition of light and form. For a pendant, the stone will hang with sartorial dignity, catching light across its table with a polished, elegant flash. The measured depth of 2.86 mm and the 6.08 by 4.06 mm face mean that metal choices matter, and a jeweller can sculpt a custom basket or bezel to showcase the gem without overwhelming it, while prong settings may maximize brilliance. Because this sapphire is both transparent and very slightly included at eye level, skilled setting can position inclusions away from dominant sightlines, ensuring a clean face up presentation and a finished piece that appears both seamless and singular.

Acquiring this Ceylon sapphire through The Natural Sapphire Company is more than a purchase, it is an invitation to join an exclusive circle that commissions and treasures exceptional gems. Our bespoke service is designed to collaborate with your vision, whether you desire an understated heirloom, a contemporary statement, or a one of a kind engagement creation. We will advise on the perfect metal, proportion, and complementary stones to elevate the emerald cut geometry, suggesting white, yellow, or rose gold, or platinum, depending on whether the aim is contrast, warmth, or the purest cool presentation of blue. Care recommendations are straightforward and conservative, avoid harsh chemicals and ultrasonic cleaners unless advised after inspection, store the piece separately to prevent abrasion, and have prongs and settings checked periodically to ensure security. Because this sapphire is heat treated, it will remain stable under normal wear conditions, and its Ceylon origin confers a desirable pedigree appreciated by collectors and connoisseurs.
