0.71 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This blue sapphire from The Natural Sapphire Company is a meticulously faceted round weighing 0.71 carat, with exact dimensions of 5.25 by 5.22 by 3.23 mm, clarity evaluated as eye clean at normal viewing distance, and an overall appearance of transparent, intense blue. The cutting style is faceted, executed as a mixed brilliant cut to marry scintillation with strong light return, with a crown composed of smaller brilliant facets to enhance surface sparkle, and a pavilion faceting schema designed to channel light back through the table for brightness and depth. The facet junctions are sharp and the polish is rated excellent, which minimizes surface graining and allows the saturated blue hue to read with uniform intensity across the table. Origin Ceylon Sri Lanka is noted for producing sapphires with vivid medium to medium dark tone and lively saturation, and this stone has been heat treated to optimize color and clarity, a standard, stable enhancement that is fully disclosed and compatible with traditional jewelry settings.

As a candidate for a generational heirloom, this sapphire combines material resilience, considered proportions, and classical optical performance to ensure longevity and enduring visual appeal. Sapphire ranks nine on the Mohs hardness scale, which gives it exceptional resistance to scratches for daily wear when set in thoughtful mountings such as a low bezel for added protection, a well engineered four or six prong head with secure girdle protection, or a custom setting in platinum or 18 karat gold to balance strength and long term maintenance. The mixed brilliant cut and excellent polish mean the stone will continue to display lively brilliance after decades, and the heat treatment applied is stable under normal use and professional cleaning. With routine inspection for prong security, occasional professional cleaning, and the documentation provided by The Natural Sapphire Company to record origin, treatment and precise measurements, this sapphire becomes an heirloom that can be reset or resized for future generations, retaining both provenance and performance, and serving as a durable, technically refined focal point in family jewelry.
