These have been in my collection since the early 2000. Made from genuine Campitos turquoise mined in Mexico. CHOICE quality light blue turquoise in LONG 24in strand graduated from 4.3mm  up to 7.9mm. Coin is a US dime for size. Fabulous matching color, very well shaped made beads. Fabulous beads for your collection or jewelry design. Photo color is close MUCH nicer in life. They don't get much better than this strand.
