Button shaped pearls in natural (un-dyed) color tones: look for a color mix of pale peach, pale pink and a bit of mauve. Most pearls have one flat side, as shown. You will occasionally find a pearl with banding around the widest part. Sizes vary from about 5.5mm to 6.2mm in diameter, but pearls will be fairly uniform in size on each individual strand. Sold by the strand.
