No reserve price Blue Sapphire - 1.65 ct - International Gemological Institute (IGI)

Blue sapphires are a highly prized variety of the mineral corundum, renowned for their captivating deep blue hues ranging from light to intense royal blue. This 1.65-carat blue sapphire has been certified by the International Gemological Institute (IGI), a respected authority in gem grading, ensuring its quality and authenticity. Blue sapphires owe their vibrant color to trace amounts of elements like iron and titanium within the corundum structure. These gemstones have a Mohs hardness of 9, making them durable choices for everyday jewelry.

Historically, blue sapphires have symbolized wisdom, virtue, and good fortune, making them popular in engagement rings and other fine jewelry. To achieve the best optical appeal, sapphires are typically cut to enhance their color saturation and brilliance. Many blue sapphires undergo heat treatment to intensify their blue color and clarify inclusions, but untreated stones, when available, can be especially valuable.

Certified blue sapphires, such as this one graded by IGI, offer confidence in parameters like color, clarity, and carat weight, essential for collectors and buyers. The intense, velvety blue shades attract those seeking classic elegance alongside gemstone durability. Whether set in rings, pendants, or earrings, a 1.65-carat blue sapphire makes a striking centerpiece that combines natural beauty with lasting appeal.
