NOTES
Please examine all photographs carefully, as they form an integral part of the description.
The gemstone has been photographed under different lighting conditions to present its appearance as accurately as possible. Slight color variations may occur depending on monitor or smartphone settings.
Natural gemstones commonly contain internal characteristics formed during their natural growth. These inclusions are normal and are considered evidence of natural origin rather than imperfections. Natural unheated sapphires are among the most sought-after colored gemstones in the world. Their rarity, durability, exceptional brilliance, and timeless elegance make them highly desirable for collectors, investors, and fine jewelry, while unheated examples are especially valued for retaining their completely natural color.
