0.57 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This offering is one transparent 0.57 carat round blue sapphire, measuring 5.47 x 5.46 x 2.77 mm. The stone is faceted in a mixed brilliant cut that combines a brilliant crown with a precision pavilion to maximize light return and scintillation. The sapphire displays an intense color intensity with a clear, vivid blue hue typical of fine Ceylon, Sri Lanka material, and it is graded eye clean when evaluated at eye level. The polish is excellent, providing crisp facet junctions and strong mirror like reflections across the table and crown facets. Enhancement by heat treatment has been applied to optimize tone and saturation, a stable and widely accepted practice in the trade that improves color without compromising structural integrity. The proportions and symmetry of this round gem ensure balanced light performance, contributing to its lively brilliance and attractive face up presence.

Because sapphire is a variety of corundum with a Mohs hardness of 9, this gem offers exceptional durability and long term resistance to scratches and everyday wear, making it well suited for rings, pendants, and other frequently worn jewellery. The stability of heat treatment means the enhanced color will remain consistent under normal wearing and care conditions, and the excellent polish and precise cutting preserve the stone's ability to return light and maintain visual appeal over time. With routine care such as gentle cleaning in warm soapy water and a soft brush, and with secure setting practices that protect the girdle and pavilion, the sapphire will continue to captivate through changing fashions and years of use. The Natural Sapphire Company provides provenance information and guidance on care and setting to ensure the gem is mounted and maintained in a manner that protects its beauty and value. This sapphire combines technical quality, enduring physical resilience, and a color and brilliance profile that will remain engaging for many years.
