1.57 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.57 carat round blue sapphire measures 7.11 x 7.05 x 3.94 mm, and is expertly faceted in a mixed brilliant cut to balance fire and depth. The gem is eye clean as judged at normal viewing distances, with no visible inclusions to interrupt its visual impact. Color is described as intense, with deep blue saturation and even tone, characteristics highly prized by connoisseurs and collectors. The polish is excellent, which enhances the crispness of each facet and contributes directly to the overall brightness and appeal. Crucially for discerning buyers, this sapphire has undergone no enhancement, preserving the natural character and rarity of the stone, and it originates from Ceylon, Sri Lanka, a source historically renowned for producing blue sapphires with lively color and attractive clarity.

The mixed brilliant cut on a round outline is a defining feature that makes this sapphire an exceptional centerpiece. This cutting style combines a faceted crown and pavilion arrangement that is optimized to return light to the viewer, creating scintillation and flashes of blue that change with movement. The proportions shown by the measurements yield a pleasing balance between diameter and depth, allowing the gem to present a strong face up size while maintaining internal light performance. An eye clean clarity grade means minimal to no internal distractions, so light travels through the stone with very little scattering, intensifying color and contrast. Excellent polish is important because even small surface abrasions can dull the appearance of a sapphire, and the finish here preserves sharp facet junctions and smooth facet planes, which are essential for maximum brilliance. For an educated buyer, the combination of natural origin, absence of heat or other treatments, eye clean clarity, intense color, and an optimized mixed brilliant cutting style represents an unusually rare and desirable intersection of qualities.

From a practical and aesthetic perspective this sapphire is ideal as a solitaire or halo center in fine jewelry, and it will perform beautifully in rings, pendants, or bespoke pieces where the gem is intended to command attention. The round shape and mixed brilliant faceting translate into predictable light behavior, simplifying design decisions for mounting and metal selection. Metals such as platinum or 18 carat gold provide both security and complementary color contrast, with platinum offering a cool and modern backdrop that amplifies blue saturation, and warm yellow gold adding classic contrast that can make the blue appear richer. Durability is excellent because sapphire is corundum with a Mohs hardness of 9, second only to diamond for everyday wear, and routine care consists of warm soapy water and a soft brush, with periodic professional inspection to ensure secure settings. At The Natural Sapphire Company we document origin and treatment status as part of our commitment to transparency, and we are available to assist with independent certification, bespoke mounting, and practical guidance to preserve the stone for generations. This untreated, eye clean Ceylon blue sapphire, with its precise dimensions and superior cut, represents a refined choice for buyers who value natural provenance, technical quality, and enduring beauty.
