2.70 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shaped blue sapphire presents as a transparent, well proportioned gemstone weighing 2.70 carats, with precise dimensions of 10.30 by 7.19 by 4.98 millimeters. The cutting style is faceted, employing a mixed brilliant cut that balances a faceted crown with pavilion facets optimized for light return. The stone displays a medium color intensity, offering a clear and lively blue tone that is neither muted nor overly saturated. Clarity is graded as slightly included when evaluated at eye level, indicating the presence of minor internal characteristics that do not detract from the overall transparency or sparkle when set. The surface finish is an excellent polish, and the stone has undergone a standard enhancement of heat treatment to enhance color and clarity. This sapphire originates from Ceylon Sri Lanka, a region historically associated with fine blue sapphires, and the specimen reflects the expected combination of color clarity and craft of that origin.

Visually the mixed brilliant cut produces dynamic internal reflections that enhance perceived brightness, while the pear outline offers classic symmetry and versatility for multiple settings. From the table the cut allows a pleasing balance between depth and spread, contributing to an elegant face up size relative to its carat weight. The slight inclusions are natural features that contribute to the gemological authenticity of the stone, and they are positioned and sized so as not to interrupt the flow of light significantly. The excellent polish allows facets to interact cleanly with light, producing crisp facet junctions and lively scintillation under directional illumination. The measurements are particularly useful when considering mounting options, with the 10.30 millimeter length and 7.19 millimeter width lending themselves to a refined solitaire, a tapered halo, or a drop style pendant.

Durability is a key consideration for any gemstone intended for frequent wear, and on the Mohs hardness scale this sapphire rates at nine, placing it among the hardest natural gemstones commonly used in jewelry. For comparison, diamond is rated ten on the same scale, topaz is eight, and quartz is seven, which illustrates why sapphire is appropriate for everyday jewelry. The high hardness means the stone is highly resistant to scratching from common materials and household items, and it is well suited to rings and other frequently worn pieces. That said, toughness and resistance to impact are distinct from hardness, and sapphires can still cleave or chip if struck sharply on an edge or point, particularly along facet junctions. For optimal protection in daily use, consider settings that shield the girdle and point, such as a bezel or a well designed prong arrangement that supports the pavilion and tip.

The provenance from Ceylon Sri Lanka and the documented attributes provide clear information for appraisal and design. The Natural Sapphire Company stands behind the described characteristics, including the 2.70 carat weight, pear shape, mixed brilliant faceting, dimensions of 10.30 by 7.19 by 4.98 millimeters, transparency, medium color intensity, slightly included clarity at eye level, excellent polish, and heat treatment. Routine care recommendations include gentle cleaning with warm soapy water and a soft brush, rinsing and drying thoroughly before re mounting, and periodic inspection by a qualified jeweler to ensure the setting remains secure. Ultrasonic cleaning is generally acceptable for heat treated natural sapphires, however any stone exhibiting significant surface reaching inclusions or structural stress should be assessed before exposure to ultrasonic or steam cleaning. This sapphire combines durable physical properties with an attractive size and refined cutting, making it a suitable choice for custom design work where a balance of color, brilliance, and everyday wearability is required.
