1.58 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This stunning transparent blue sapphire, offered by The Natural Sapphire Company, weighs 1.58 carats and is presented in an elegant cushion shape with precise dimensions of 6.92 by 6.86 by 3.77 millimeters. The cutting style is faceted with a mixed brilliant cut, combining the depth and color retention of step facets with the sparkle and return of brilliant facets. The gem displays medium color intensity and an excellent polish, and it has been heat treated in a stable and fully disclosed manner to enhance its color and clarity. Originating from Ceylon, Sri Lanka, this sapphire embodies the clarity of a stone that appears essentially flawless to the unaided eye, making it a compelling choice for the buyer who values both visual purity and technical quality.

The mixed brilliant facet arrangement is a deliberate choice to maximize the stone's optical performance. The cushion outline provides a generous table and broad crown facets that allow the blue to present uniformly in face up view, while the pavilion facets are tuned to return light with lively scintillation. With a depth that works harmoniously with the given diameters, the proportions produce a balanced light path that avoids the trapped light that can dull color or reduce apparent size. Excellent polish on every facet ensures that light enters and exits with minimal disruption, creating an even, glasslike surface that enhances both brilliance and brilliance related phenomena such as flash and scintillation. From every viewing angle the precision cutting and superior finish create an effect of seamless beauty, allowing the sapphire to glow consistently whether set in jewelry or examined in hand.

Clarity is graded as very slightly included when evaluated at eye level, a grade that should be interpreted in context for an educated buyer. Very slight inclusions indicate the presence of tiny internal features that do not materially affect transparency or visual appeal in normal wear, and in this instance the inclusions are exceptionally well positioned and masked by the facet pattern. Because the mixed brilliant cutting style disperses and redirects light, these inclusions are rendered inconspicuous in the face up presentation, giving the stone an essentially eye clean appearance. Under magnification trained gemologists may note the inclusions, which is useful information for accurately grading and valuing the gem, but in practical terms the stone reads as flawless to the eye, contributing to a serene, uninterrupted color field that enhances perceived purity and elegance.

The medium blue hue combined with Ceylon origin contributes substantially to the stone's desirability and investment profile. Ceylon sapphires are prized for their lively, medium toned blues that balance saturation and brightness, offering a vivid presence that is not overly dark or inky. The disclosed heat treatment is a widely accepted, stable enhancement that refines color and clarity without compromising structural integrity, and buyers who are familiar with the trade recognize such treatment as standard for many high quality sapphires. Provenance from Sri Lanka adds provenance value, as collectors and connoisseurs often seek the characteristic vibrancy and clarity associated with the island s deposits. For a discerning purchaser the combination of origin, treatment, and natural qualities results in a gem that represents both immediate aesthetic appeal and long term value retention.

Sapphires are exceptionally durable, rating nine on the Mohs hardness scale, which makes this cushion sapphire a superb choice for everyday jewelry such as rings, pendants, or heirloom pieces meant to be worn and enjoyed. The gem s excellent polish and stable treatment ensure that it will maintain its brilliance and color when set and cared for in accordance with standard gem care practices. When mounted by a skilled jeweler the stone will present a face up presence that appears flawless, with even color distribution and lively light return from every angle, qualities that speak to both the technical excellence of the cutting and the intrinsic quality of the rough material. At The Natural Sapphire Company we select stones that meet exacting standards for proportion, finish, and ethical disclosure, and this 1.58 carat Ceylon cushion sapphire exemplifies those standards for buyers seeking a gem that combines educated provenance, practical durability, and an eye clean, flawless appearance in everyday wear.
