1.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent, emerald cut blue sapphire from Ceylon presented by The Natural Sapphire Company is a refined example of classic corundum that suits a discerning high end gemstone collection. The gem weighs 1.07 carats and measures 6.88 x 5.04 x 3.06 mm, dimensions that make it versatile for both intimate jewelry designs and as a curated specimen. The stone is fashioned in an emerald cut, a step cut that emphasizes clarity and color depth through broad, flat facets and a generous table. Clarity is graded as very slightly included when evaluated at eye level, indicating minimal internal features that do not materially affect visual appeal under normal viewing. The color intensity is described as dark, and the polish is excellent, producing sharp facet junctions and a reflective surface that enhances the stone's overall presentation. The piece has undergone standard heat treatment, a widely accepted and disclosed enhancement in the trade, and its origin is Ceylon Sri Lanka, a source long respected for producing sapphires with attractive blue hues.

Optically, this sapphire is characterized by a concentrated, saturated blue that reads as deep and velvety in typical lighting conditions, with controlled flashes of brighter blue where the step facets create windows of lighter tone. The emerald cut tends to concentrate color toward the center of the stone while allowing the pavilion facets to return rich blue tones, creating a balance of depth and visual breadth that appeals to collectors who favor structural clarity and color integrity. Because the clarity is very slightly included at eye level, inclusions are minor and typically confined to small crystals or subtle needle like growth features that are consistent with natural corundum. These inclusions do not disrupt the stone's transparency, and they serve as natural identifiers for gemological assessment. The excellent polish complements the cut by ensuring that light moves cleanly across the facet planes, enhancing lustre and contrast between dark and lighter blue areas. The stone’s dimensions and cut symmetry contribute to balanced light performance, making the sapphire suitable for close inspection and display among other premium gems.

From a practical and curatorial perspective, this 1.07 carat emerald cut Ceylon blue sapphire is well suited to augment a high end gemstone collection, both as an object of study and as a center stone for refined jewelry commissions. Its size and proportions are amenable to a variety of settings, including classic four prong solitaire mounts, protective bezel designs for everyday wear, or sophisticated bespoke pieces where the step cut can be framed by fine metalwork or accent diamonds. As corundum ranks nine on the Mohs scale of hardness, the gem offers superior durability for regular wear when set and cared for properly, while still benefiting from prudent handling to avoid hard knocks to facet edges. The documented heat treatment should be noted in any provenance record, and The Natural Sapphire Company is committed to transparent disclosure regarding treatments and origin. For collectors seeking formal documentation, independent gemological reports and imaging can be provided upon request to support valuation and authentication. Routine care recommendations include gentle cleaning with mild soap and water, and professional evaluation before using ultrasonic or steam cleaners, especially following any setting work.

Overall, this sapphire represents a compelling addition to a high end collection where quality of color, cut, and provenance are primary considerations. The emerald cut presentation from Ceylon offers a distinct aesthetic compared with the more common brilliant cuts, prioritizing architectural elegance and a focused expression of blue. The combination of very slightly included clarity, dark color intensity, and excellent polish produces a stone that reads as both classic and quietly bold, suitable for curators, private collectors, and designers seeking a refined center gem with clear documentation and traceable origin. The Natural Sapphire Company provides detailed information and specialist guidance for collectors considering this stone, ensuring that acquisition is supported by full disclosure and professional recommendations for mounting and care.
