The Magic square ring was inspired by
old Jewish traditions that used to create magic squares from
Hebrew letters for protection and healing.
A magic square is square table in which each all numbers columns, from all directions, have the same numerical value. In Hebrew each letter has also a numerical value. In the magic square ring the numerical value of each column is 15 which is equivalent to the letters YOD, HE, used as one of Hebrew names of G-D.
This magic square is made of 3 letters in each row. If you multiply the column of one dimension you get 3*3*3= 27 which is the number of Hebrew letters.
The magic square ring is made to protect and heal the wearer.
