0.75 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a classically proportioned emerald cut weighing 0.75 carat, with the table and step facets arranged to optimize even color distribution and crisp step reflections. The table measures relative to the length and width to give a broad, lucid face for observing the stone at glance, while the overall dimensions of 5.67 by 4.74 by 3.00 millimeters yield a compact profile that balances surface presence with depth. The emerald cut, with its parallel facet planes and truncated corners, emphasizes clarity and color over scintillation, creating a series of linear flashes along the crown and pavilion. This cut demands exacting symmetry and pavilion depth control to produce efficient light return, and the cutter has calibrated the crown height and pavilion angle to maintain focused, tabular brilliance without leaking light through the pavilion. The material is transparent, allowing internal features to be studied easily under loupe and to present a vivid window of color in mounted settings.

Color evaluation for this specimen is medium intense blue, sourced from Ceylon in Sri Lanka, which is known for producing sapphires with a bright, lively blue that often leans slightly toward a cornflower to violet blue depending on viewing face. In this example the saturation sits squarely in the medium intense range, producing a pleasing balance between vibrancy and wearability. The stone exhibits natural dichroism typical of corundum, with subtle variations between a purer blue and a slightly cooler blue violet when rotated, which enriches the visual experience and can appear as depth in different lighting. Clarity is graded slightly included at eye level, meaning small inclusions are present under normal viewing without magnification altering the gemology of the piece. These internal characteristics are typical of natural material and establish provenance, while also affecting light transmission in minor ways that contribute to the stone character rather than detract from it. The polish on the pavilion and crown is excellent, resulting in crisp facet junctions and well defined facet planes, and importantly the stone has no enhancement, remaining untreated so that the color and clarity reflect its natural state.

From a gemological perspective the stone benefits from corundum properties which include a high refractive index and strong durability, with a typical refractive index range for sapphire in the narrow band around 1.76 to 1.77 and a specific gravity near 4.00, contributing to substantial heft for its size. The combination of excellent polish and precise step cutting produces clean, linear reflections that emphasize the blue tone without excessive dispersion. For setting, this emerald cut sapphire is well suited to secure prong work that protects the truncated corners, or to a custom four step bezel that follows the octagonal outline to highlight the geometric nature of the cut. Metal choices will influence apparent color, with white metals maintaining a cooler aesthetic and yellow gold warming the stone gently. Because the gem is untreated and durable, it is an excellent choice for everyday wear in engagement rings and fine dress jewelry, however attention to corner protection is recommended to guard against accidental knocks given the stepped pavilion geometry. At The Natural Sapphire Company we recommend mounts that allow the table to sit close to the finger plane for visual impact, while providing sufficient gallery clearance to showcase the step reflections when viewed from the side.

Beyond physical and optical properties, this blue sapphire carries traditional metaphysical associations that many clients seek for emotional and ritual purposes. Blue sapphire has a long history as a stone of wisdom, clarity, and calm, and it is commonly associated with enhanced mental focus, disciplined thought, and clearer communication. In energetic practice it is often linked to the throat chakra for improved self expression, as well as to higher mind centers for cultivating insight and spiritual perspective. Wearers report that the steady, cool blue of a Ceylon sapphire can act as a stabilizing influence during periods of decision making, helping to reduce scattered thinking and to promote deliberate action. It is also considered a protective stone, valued historically for its ability to shield the wearer from negative influences while encouraging integrity and faithful relationships. These metaphysical properties are traditional in nature and reflect cultural and personal beliefs rather than measurable medical effects, and they complement the gemological value of this natural, unenhanced sapphire as both an object of beauty and a meaningful personal talisman.
