1.34 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.34 carat oval blue sapphire is a finely executed example of classical gem cutting, presented by The Natural Sapphire Company. The stone measures 7.31 x 5.48 x 3.72 mm, and has been faceted in a mixed brilliant cut that pairs a brilliant style crown with a step influenced pavilion architecture, optimizing both volume and light return. The oval outline is proportioned to maximize face up color while preserving weight, and the combination of crown angle geometry and pavilion facet arrangement yields balanced contrast and scintillation. The girdle has been faceted to a practical thickness to preserve durability during setting while minimizing excess weight, and the overall dimensions produce a pleasing table to depth ratio that supports consistent light performance across the face of the gem.

Color is the primary character of this sapphire, evaluated as intense in saturation, and displaying that classic Ceylon blue that collectors and connoisseurs seek. The hue is a pure blue leaning slightly toward a cool zone that is typical of material from Ceylon Sri Lanka, with strong saturation that reads as deep without appearing overly dark. Color distribution is uniform to the eye, with only minor natural variation when the stone is examined at oblique angles, and the gem shows the expected pleochroic behavior of corundum with subtle shifts between stronger and softer blue directions when rotated. The clarity has been graded as slightly included when evaluated at eye level, and these natural internal characteristics are consistent with an unfractured crystal origin, they sit beneath the surface so they do not dominate the face up appearance, and they contribute to the stone character without compromising brilliance or structural integrity.

The cutting style and excellent polish produce predictable and desirable light behavior under diverse lighting environments. Under strong daylight or full spectrum illumination the mixed brilliant design returns clean white light flashes from the crown facets, while deep blue color contrasts are accentuated by the pavillion architecture producing a lively depth of tone. Under warm incandescent illumination the sapphire tends to register a slightly warmer blue, the intense saturation reads as velvety and plush, and small scintillation facets offer rounded, softer sparkle. Under cool LED sources the stone shows higher contrast with crisp white flashes and an electric blue presence, the facet junctions throw compact scintillation which emphasizes the mixed brilliant design, and pleochroic shifts become more apparent as you tip the gem. In dim or indirect lighting the internal depth and velvety body color remain noticeable, giving the stone a presence that reads as both refined and substantial, and the excellent polish ensures that light crossing the crown face is not scattered by surface irregularities.

From a practical and setting perspective this sapphire benefits from both its cut profile and the stability of standard heat treatment, which is a durable enhancement that improves color homogenization without altering the fundamental crystal structure. The stone is corundum, hardness nine on the Mohs scale, which makes it appropriate for daily wear in rings, pendants, or more secure bezel set styles, while prong settings that allow crown exposure will maximize face up brilliance and color. For mounting advice, orienting the long axis of the oval to follow the finger or neckline will enhance perceived size and create an elegant visual flow, and leaving a modest table ratio will preserve light return while protecting pavilion integrity. At The Natural Sapphire Company we document origin, treatment, and exact dimensions, and we welcome requests for additional lighting images and setting simulations so that you may evaluate how this gem will perform in your intended design.
