Bracelet features twenty 5x7 oval peridot, and eleven 3x4mm oval peridot! That is a lot of genuine peridot, August's birthstone. Most "peridot" on the market is not real and does not have this incredible light. Toggle closure will adjust from 6.75inches to 7.5 inches, to 8 inches maximum, so it will fit a small to large sized wrist but not an extra large wrist. This is a piece of a lifetime and a great value with a total of 31 faceted stones.
