These beads measure 6.5mm in diameter with a 0.5mm drill hole. These stunning, specially curated strands feature a highly unique charcoal grey color palette. Our dazzling opal rondelles offer a striking appearance perfect for all sorts of designs from necklaces to earrings and bracelets. These unique beauties are destined to inspire jewelry creations notable in their finely speckled texture and high-quality. Beads are color enhanced on a white opal base. We recommend washing these beads in warm water before designing to remove any residual dye that has not set into the piece.
