A Guide to Engagement Rings
Fancy Coloured Loose Diamonds
Natural fancy-colored diamonds derive their distinct hues from rare geological conditions. Blue diamonds owe their colour to trace elements of boron, while the presence of nitrogen forms yellow diamonds. Pink diamonds acquire their tint not from trace elements, but through intense heat and pressure that alter their crystal lattice. Green diamonds are the rare result of natural radiation exposure deep underground, and black diamonds achieve their striking, opaque appearance from dense clusters of dark inclusions like graphite. Each stone represents a specific, highly coveted natural anomaly, offering the wearer a truly unique, billion-year-old treasure.
