The science of numerology says that each letter represents some value.
Yet another method to determine the suitability of a particular gemstone is based on the value of each letter. For finding out the exact day in any month whose vibrations will be favorable, one has to work out the occult number produced by the letters of the name. This process is ancient and based on Chaldean and Hebrew alphabet. In this the total value of all the letters is added to form a single digit.
