6.96 Ct. Multi Color Rough Sapphire Crystal from Ceylon (Sri Lanka)

This translucent multi color sapphire weighs 6.96 carats and measures 19.87 x 8.41 x 7.32 mm, offering a distinctive elongated profile in a various shape rough crystal cut. The gem displays medium color intensity and an excellent polish that highlights subtle hue variations across its surface, while the clarity is graded as very slightly included when evaluated at eye level. This stone is untreated, with no enhancement reported, and its documented origin is Ceylon, Sri Lanka. The Natural Sapphire Company presents this specimen as a natural, unheated example of Sri Lankan sapphire material, with the rough crystal cut preserved to retain character and natural form. Photographic views indicate an even translucency and a surface finish that will respond well to careful setting, particularly when the design accounts for its length and organic silhouette.

On the Mohs scale of mineral hardness, corundum, the mineral species of sapphire, rates at 9. This places sapphire among the hardest gem materials used in jewelry, second only to diamond on the Mohs scale, and makes it highly resistant to scratching and abrasion for everyday wear. For comparison, White Opal typically ranges from about 5.5 to 6.5 on the Mohs scale, and it is consequently more susceptible to scratching, chipping, and surface abrasion, and more sensitive to sudden temperature and moisture changes. The practical implications are that this Ceylon sapphire is well suited to daily wear in rings and bracelets when set securely, while White Opal requires more protective settings and gentler care. Given the rough crystal cut and natural inclusions of this piece, a setting that protects the stone edges, such as a bezel or substantial prong work, is recommended to preserve the stone integrity. Routine cleaning with mild soap and warm water and avoidance of harsh chemicals and extreme thermal shock will maintain the stone appearance and durability.
