A Royal blue diamond is a rare and valuable diamond whose color comes from atomic-level distortions and plastic deformation during its formation, rather than a chemical impurity like nitrogen. These diamonds can have a range of shades, from orangey-pink to purplish-pink, and are graded for their color intensity, with "fancy vivid" being the highest. Once almost exclusively sourced from the now-closed Argyle mine, they are among the world's most coveted and expensive gemstones. Key Characteristics Color Origin: The Royal blue color is not due to a specific chemical element but to structural imperfections, specifically plastic deformation of the crystal lattice under immense pressure and temperature during its creation. Rarity: Pink diamonds are incredibly rare, making up a tiny fraction of global diamond production. Shades and Intensity: The color can vary, with secondary overtones of purple, orange, or brown being common. Color intensity is graded on a scale from Faint Pink to Fancy Vivid Pink, with the latter commanding the highest prices. Internal Structure: Many pink diamonds contain internal lines or patches of pink graining, a result of the same pressure that gives them their color. Provenance: Historically, the majority of pink diamonds have come from the Argyle mine in Australia. Factors Influencing Value Color Intensity and Hue: More vibrant and pure pink or purplish-pink colors are the most valuable. Clarity: Due to the high-pressure formation, achieving high clarity grades can be difficult, making high-clarity pink diamonds even rarer. Rarity: The overall scarcity of natural pink diamonds significantly contributes to their high market value.
