Yellow rough sapphire from Sri Lanka 5.16 carats – 9 mm

Yellow sapphire is a rare gemstone with a rich history and captivating appearance. As a member of the corundum family of minerals, it has characteristics similar to related stones — ruby and blue sapphire. It is known for its exceptional durability and luster, making it a popular choice for jewelry.

Yellow sapphires are formed in the same way as other sapphires, such as blue ones. The mineral corundum consists of aluminum and oxygen. Therefore, the unique and attractive yellow color of these precious stones is determined by the presence of trace elements, metals such as iron and titanium, as well as the crystal structure of the mineral. The intensity of the yellow color may vary depending on the concentration of these elements. Yellow sapphires can also be colored naturally by exposure to weak radiation in the earth's crust or as a result of laboratory irradiation.

Yellow sapphires are often appreciated for the impressive variety of colors that can convey the essence of the sun and nature to the naked eye. The bright shades of these gems can vary greatly, from a rich canary yellow to a softer, muted lemon yellow. They may also contain shades of green, yellow gold or orange, which gives each stone a unique character that distinguishes it from other precious stones.
