Blue Nile’s colored Gemstone Enhancement Policy

Blue Nile offers consumers only the highest quality, authentic gemstones. Our colored gemstones undergo rigorous internal inspections by our trained gemologists to ensure they meet our stringent quality standards.

Due to their rarity and unique visual properties, nearly all colored gemstones sold at fine jewelers, including Blue Nile, are enhanced using various techniques.
