To be able to identify genuine Thai silk easily, Thailand's Agriculture Ministry uses a peacock emblem to authenticate Thai silk and protect it from imitations. The peacock emblem serves as a guarantee of quality and it comes in four different colors based on specific silk types and production process.[8] These are the following:
Gold peacock: Indicates the premium Royal Thai Silk, a product of native Thai silkworm breeds and traditional hand-made production.
Silver peacock: Indicates Classic Thai Silk, developed from specific silkworm breeds and hand-made production.
Blue peacock: Indicates Thai Silk, a product of pure silk threads and with no specific production method (allows chemical dyes).
Green peacock: Indicates Thai Silk Blend, a product of silk blended with other fabrics and with no specific production method.
