2.06 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 2.06 carats and presents an oval outline with dimensions of 8.53 by 7.02 by 3.99 millimeters, yielding a length to width ratio of approximately 1.22. The cutter employed a mixed brilliant faceting scheme, which combines a brilliant facet arrangement on the crown with a modified pavilion design to balance strong light return and optimal color saturation. The measured pavilion depth of 3.99 millimeters against the average diameter produces a depth of roughly 51.4 percent, a proportion that sits within the preferred range for oval sapphires to maximize face up presence without excessive windowing. Facet junctions and symmetry are executed to a high standard, and the polish has been graded excellent, indicating meticulous lapidary finishing that produces crisp facet edges and minimal surface abrasion. Clarity is described as very slightly included when evaluated at eye level, meaning that inclusions are minor, do not interrupt the primary light path, and will not readily impact setting or daily wear. These combined proportions and finish characteristics make this stone particularly predictable to set and calibrate for precise custom fabrication.

Color in this sapphire is described as dark intensity, a saturation level that yields a deep, velvety blue when viewed face up under typical lighting. The stone’s origin of Ceylon Sri Lanka contributes to its tonal quality, as Ceylon material is noted for a spectrum that can range from vivid medium blue to richer deep blue. Because the cutter preserved substantial weight and depth, the mixed brilliant cut moderates face up darkness while maintaining strong internal reflection, providing scintillation across the table and crown facets. Heat treatment is reported as the enhancement, a stable and accepted process in the trade that improves color homogeneity and reduces the visibility of certain silk like inclusions. Optical behavior includes subtle pleochroism, observable as slight shifts in blue intensity when the stone is rotated, which is typical and can be used to advantage in orientation during setting so that the most desirable hue is presented to the viewer. The combination of dark color intensity and excellent polish reduces the risk of windowing under natural light, ensuring a visually rich center stone for most mounting styles.

From the perspective of custom jewelry design this oval sapphire is exceptionally well suited to serve as a primary center gem. Its 2.06 carat weight and 8.53 by 7.02 millimeter face up dimensions provide a comfortable visual scale for single stone rings, pendants, and solitaire earrings, while the slightly elongated proportion lends a classic elegant silhouette that flatters the finger or neckline. The pavilion depth near 51 percent permits secure bezel or prong settings without excessive lifting of the stone above the mounting plane, and it allows gold or platinum cups to be engineered with standard seat depths so that the girdle sits close to the intended profile. For designers seeking contrast, pairing this dark blue sapphire with a warm yellow gold bezel will enhance the richness of tone, while white metals emphasize brilliance and deliver a cooler aesthetic. The very slightly included clarity grade supports close setting work including halo arrangements and pave shoulders because inclusions are not prominent at face up view, and the excellent polish supports precision mountings where facet intersections meet bezels or claws cleanly. For bespoke projects where light performance is a priority, orient the stone so that the pavilion facets align with the primary light source and consider an open gallery or low profile prong system to permit maximum light access into the pavilion.

At The Natural Sapphire Company we recommend considering this stone for designs where color depth and classic oval form are desired, including three stone rings where side stones can be calibrated to complement the saturation, and pendant settings that capitalize on the oval silhouette for vertical emphasis. Technical guidance for the bench includes accounting for the pavilion length when cutting the seat, confirming that the setting clearance accommodates the 3.99 millimeter depth, and using a subtle tilt in the seat axis if the cutter or setter wishes to favor one pleochroic orientation. Heat treatment is stable, however standard precautions for daily wear such as avoiding harsh thermal shock and mechanical impacts are advisable.
