2.59 Ct. Blue Sapphire from Thailand

This transparent blue sapphire weighs 2.59 carats, and is presented in an elegant pear shape with precise dimensions of 7.67 x 10.55 x 4.00 mm, offering a proportion that balances presence and practicality for a variety of fine jewelry designs. The gem originates from Thailand, a region known for producing sapphires with deep, saturated tones, and it displays a vivid color intensity that is consistent across the table and crown. Transparency is notable throughout the stone, allowing light to penetrate and interact with the internal facets, and the overall appearance is one of focused, saturated blue that reads richly in both daylight and evening illumination. The stated enhancement is heat treated, a standard and stable practice in the trade that refines tone and clarity while maintaining the natural origin and structural integrity of the corundum. The combination of carat weight, dimensions, and vivid color intensity results in a sapphire that is substantial enough to command attention, while remaining versatile for use as a centerpiece in rings, pendants, or bespoke settings.

Cut and facet architecture are defining attributes of this sapphire, as it is fashioned with a mixed brilliant cut that optimizes both scintillation and color delivery. The mixed brilliant style combines a brilliant faceted crown with a more step influenced pavilion, creating an interaction between lively flash and deep color saturation that enhances perceived depth without sacrificing sparkle. The pear outline has been executed with careful symmetry, producing a balanced silhouette with a smoothly tapering point and a broad rounded shoulder that provides visual stability when set. Excellent polish has been applied to all facets, minimizing surface diffusion and allowing light to reflect with crispness and contrast, which is particularly important for gemstones with saturated colors. The facet junctions are clean and sharp, contributing to well defined facet reflections, and the result is a sapphire that reads as both precise and luminous, capable of serving as a true focal point in a refined jewelry composition.

Clarity is graded as very very slightly included, evaluated at eye level, which indicates that the stone is exceptionally clean to the unaided eye with only minor internal features visible under careful inspection. These minute inclusions do not materially affect transparency, nor do they detract from the stone's ability to transmit light and exhibit scintillation. In fact, the minimal internal features can contribute to natural character without compromising brilliance or structural integrity. The vivid color intensity is a critical attribute, producing a strong, saturated blue that maintains attractiveness across viewing conditions. Given the heat treated enhancement, color stability under normal wear and environmental conditions is reliable, and the treatment is an established, accepted practice that enhances color without introducing instability. Origin from Thailand adds context to the gemology, as Thai sapphires are often prized for their deep, velvety blues and consistent material quality. Hardness and durability inherent to corundum make this sapphire suitable for everyday wear when properly set, and the gem tolerates routine jewelry cleaning methods compatible with heat treated natural stones.

For practical use and design integration, this sapphire is well suited to become a centerpiece in a variety of settings that emphasize its pear outline and mixed brilliant faceting. Classic prong settings allow maximum light entry to the pavilion and will showcase the stone's brilliance and color, while bezel or halo configurations can emphasize the silhouette and provide additional protection to the pointed end. Custom designers may choose tapered shoulder profiles or asymmetric mounting details to complement the pear shape, and the measured depth of 4.00 mm supports secure bezel engagement or shadowed pavillion access for expert setting. Documentation of origin and treatment is available, and careful provenance records are maintained by The Natural Sapphire Company, ensuring clarity on the gemological attributes and history of this individual stone. Routine care recommendations include periodic professional inspections of the setting, gentle cleaning with warm soapy water and a soft brush, and avoidance of prolonged exposure to harsh chemicals or intense thermal shock. Presented as a focused specimen with exemplary cut, excellent polish, very very slightly included clarity at eye level, and vivid color, this 2.59 carat pear shape blue sapphire embodies the qualities expected of a centerpiece gem, and it is presented with the pedigree and documentation that support confident selection for refined jewelry projects.
