0.73 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite natural blue sapphire from The Natural Sapphire Company is a 0.73 carat, transparent emerald cut, with precise dimensions of 6.74 x 3.75 x 2.98 mm, a clarity grade of very very slightly included, evaluated at eye level, and a vivid color intensity with an excellent polish. The emerald cut presents a series of parallel step facets that emphasize the stone’s internal clarity and deliver a clean, architectural elegance that many collectors and connoisseurs prefer for colored stones. Originating in Ceylon Sri Lanka, this sapphire carries the hallmark character of Sri Lankan material, a lively, saturated blue with a subtly velvety overtone that reads as vivid and deeply appealing in daylight and artificial light alike. The stone has been heat treated, a stable and widely accepted enhancement in the trade, disclosed and performed to enhance color saturation and clarity without compromising long term stability.

From a gemological perspective this sapphire offers a compelling combination of attributes that an educated buyer will recognize as rare and desirable. The emerald cut’s elongated profile with a length to width ratio near 1.8 creates a poised face up size that maximizes visible color while maintaining crisp step facets that direct light in broad flashes, accentuating the vivid blue rather than creating a scatter of white brilliance. The clarity grade of very very slightly included, observed at eye level, indicates that inclusions are minimal and do not detract from the stone’s visual purity, allowing the intense Ceylon blue to remain uninterrupted across the table. The excellent polish reflects expert lapidary work, yielding clean facet junctions and smooth planes that enhance light return and the apparent depth of color. Heat treatment is the most common and stable enhancement for sapphire, undertaken to refine color and reduce the appearance of minor clouds, and it is fully disclosed here to maintain transparency and trade standard provenance.

This sapphire is a durable, long term choice for an heirloom quality jewel, suited to both classic and contemporary settings, and its natural beauty will continue to captivate over the years. Corundum is one of the hardest gem materials, offering significant resistance to everyday wear, and the emerald cut offers a low profile that sits securely in a bezel or in well engineered prong work, preserving facet edges and polish. With routine care consisting of warm water, mild soap and a soft brush, and professional inspection after mounting, the stone’s vivid tone and polished surfaces will remain remarkably stable, and the disclosed heat treatment will not alter with normal use. From a collector and investor standpoint, sapphires of Ceylon origin with vivid saturation, transparent material and minimal eye level inclusions are consistently sought after, and this 0.73 carat emerald cut example represents a balanced, market aware choice that blends aesthetic refinement with sound gemological credentials.
