Found in the Sahara Desert in Mali, these 1000+ years old conical and round banded beads display a wonderful iridescence ( which is showing as white in the scan ). Iridescence is normally
thought to be the result of prolonged exposure of glass to an acidic environment. As the desert sands are not normally acidic, a possibility is that these beads and others, showing very similar characteristics,
might have been been buried with their owners, whose decomposition resulted in a surrounding area of acidity. Strand length 4.5 ins / 12 cm Largest conical bead 10 x 9 mm Centre bead is a 7 x 8 mm ancient
Islamic triangular 'eye' bead asm 237-01 £38
