1.75 Ct. Bluish Grey Star Sapphire from Ceylon (Sri Lanka)

One exquisite translucent 1.75 carat round bluish grey star sapphire awaits, measuring 7.48 x 7.34 x 2.90 mm, fashioned as a classic cabochon to best display its asterism. This gem shows a delicate star that glides across its surface with movement, a quality that many mass market stones lack because they are either heavily treated or synthetic. The clarity grade is very slightly included at eye level, which is a favorable balance between natural character and visual purity, and the light color intensity gives this sapphire a subtle, versatile tone that complements both white and yellow metals. The polish is excellent, which enhances luster and the sharpness of the star, and importantly, there has been no enhancement, making this a true natural Ceylon stone with provenance from Sri Lanka. Compared to commonly available heat treated or diffused star sapphires, this untreated Ceylon example retains rarity and resale value, and compared to darker or heavily included alternatives, it offers brighter star contrast and cleaner appearance while preserving natural origin and integrity.

Durability is a key advantage for everyday wear, and this sapphire scores a nine on the Mohs hardness scale, placing it just below diamond and well above popular gemstones such as topaz and quartz, which means it resists scratching and maintains a polished finish longer in regular use. That exceptional hardness, combined with the cabochon cut that protects facet edges, makes this stone an excellent choice for rings, pendants, or heirloom clasps that see regular wear. When assessing value, you will find that natural, unenhanced Ceylon star sapphires of this quality are rarer than their treated counterparts, and the balance of carat weight, pleasing light bluish grey hue, clean eye level clarity, and superb polish offers an outstanding combination of beauty and longevity. The Natural Sapphire Company presents this piece as a superior option for discerning buyers seeking authenticity, durability, and the unique celestial appeal of a genuine star sapphire, and we are ready to advise on settings that will showcase the star and protect the gem for generations.
