Morse code is an alphabet in which letters are represented by combinations of long and short signals.

Each character is a unique sequence of dots and dashes.

For gemstone versions, dots and dashes are represented by round beads in alternated color, for example, a volcanic basalt bead for space, a white jade bead for a dash, and an amethyst bead for a dash. 

For beaded versions, dots and dashes are represented by round and tube beads.

The message reads from the snap button towards the loop. A decipher card is included.
