Blue sapphires are esteemed for their striking deep blue color and remarkable hardness, second only to diamonds on the Mohs scale. This blue sapphire weighs 1.40 carats and is certified by the International Gemological Institute (IGI), which assures gemstone quality and origin verification. Sapphires are a variety of corundum, composed primarily of aluminum oxide, with the blue color resulting from trace amounts of iron and titanium. These stones form in metamorphic or igneous rocks and have been cherished since antiquity for their beauty and toughness, which make them ideal for all types of jewelry. The saturation and clarity of a blue sapphire directly affect its value, with vivid, evenly colored stones being most sought after. This sapphire’s certification from IGI adds trustworthiness, appealing to collectors and those seeking a fine, natural gemstone with assured provenance.
