The beautiful bands of black agate contrast black and brown with cream shades. Black agate obtains the contrasting patterns from an age-old dyeing process that enhances the stone's natural beauty. Flat round beads vary slightly in size and thickness. Shades and patterns range from translucent to opaque.
