1 pcs Blue Sapphire - 5.11 ct - Gem research Swiss Lab (GRS) - Cornflower

Blue sapphire is a precious gemstone variety of the mineral corundum, prized for its stunning blue hue and exceptional hardness, second only to diamond. The specific term "cornflower blue" denotes a vibrant, medium blue color that is highly sought after in the gem world for its striking and luminous quality. The 5.11 carat size indicates a substantial crystal, notable for use in high-end jewelry such as rings and necklaces. Such sapphires are often characterized by their clarity and depth of color, attributes that significantly influence their value. The certification from the Gem Research Swiss Lab (GRS) adds credibility by verifying the gem's authenticity and quality, ensuring it meets rigorous standards. Blue sapphires traditionally symbolize wisdom, loyalty, and nobility, making them popular choices for engagement rings and heirloom pieces. Their formation occurs deep within the Earth's crust under high pressure and temperature conditions, which contribute to their durable crystalline structure and vibrant coloration created by trace amounts of elements like iron and titanium.
