This is such a big , beautiful bead - it has shades of blue and just a touch of white ( when you hold it to the light there are some areas where it is thinner and the color is like a colbalt blue bottle ). This bead is beautifully carved with four large petals and four smaller tucked in between . It is drilled through the center . It measures petal point to petal point 60mm x 60mm and is almost 9mm thick . If you measure from side to side ( where the petals are tucked under ) it is 45mm x 45mm .
