7.58 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This one beautiful transparent 7.58 carat emerald cut blue sapphire from Ceylon, Sri Lanka, is presented by The Natural Sapphire Company as a statement quality gemstone for an engagement ring that balances presence and refinement. The stone measures 11.74 x 8.86 x 7.18 mm, and its emerald cut gives it an elegant rectangular table with step cuts that emphasize color and clarity. Graded as very slightly included when evaluated at eye level, this sapphire displays exceptional transparency for a stone of its size, and an excellent polish that enhances the crispness of each facet. The color intensity registers as medium intense, which means the blue reads vivid but not overly dark, allowing for lively interaction with light while preserving excellent saturation across the table and pavilion. The sapphire has been responsibly heat treated, a standard and widely accepted enhancement that intensifies color and improves clarity without compromising the natural character or durability of the crystal. Photographs show the stone both loose and on hand to illustrate how the dimensions translate to finger presence, and to demonstrate the clean step pattern and even color distribution that make this gem desirable to the discerning buyer.

From a gemological perspective, this Ceylon sapphire exhibits characteristics that are especially appealing to those who appreciate technical quality as well as aesthetic beauty. The emerald cut, with its broad, flat facets, creates an architectural play of light and shadow, often described as a hall of mirrors effect, that flatters stones with strong color and good clarity. In this case, the medium intense blue presents a pure, classic sapphire hue with subtle secondary blue violet notes that are typical of high quality Ceylon material, attributable to trace amounts of iron and titanium incorporated during formation. The very slightly included clarity grade indicates that inclusions are minor and not obvious to the unaided eye, preserving the gem’s visual purity when set. Excellent polish across the table, step facets, and girdle ensures that light transmission is maximized and that facet junctions remain crisp, producing stable and attractive reflections rather than the scattered flash seen in lesser finishes. Heat treatment in sapphires from Sri Lanka is generally stable and permanent, and when performed correctly it removes or reduces silk and color zoning while revealing the stone’s best possible tone and saturation.

For an engagement ring this sapphire is particularly well suited, combining durability, classic style, and strong visual appeal. Sapphire rates at 9 on the Mohs hardness scale, which makes it second only to diamond in terms of resistance to scratching among commonly used gemstones, and its toughness when set properly supports daily wear. The emerald cut profile keeps the stone low to the finger relative to similarly weighted brilliant cuts, which adds practicality and reduces snagging, while the large table and clean facets deliver a focused, elegant color field that reads as sophisticated and modern. At 7.58 carats the stone offers impressive face up size, and the 11.74 x 8.86 mm dimensions provide a well balanced rectangular silhouette that suits a range of mounting styles, from classic four or six prong solitaire settings to halo designs that add contrast and sparkle. Because step cuts accentuate clarity, the very slightly included grade plays to an advantage here, revealing the purity and depth of the blue rather than distracting from it. Metal choices can further refine the presentation, with platinum or white gold delivering a crisp, contemporary look, while yellow or rose gold will warm and enrich the blue for a more vintage or romantic expression. A secure setting and professional mounting will protect the girdle and pavilion, preserving the sapphire for generations.
