There are not many books on gems. Manik Chand Jain , in this book "Occult Power of Gems" has done a Yeoman service both to the gems and to their  wearer. Valued readers very well received the book. Their response was really flattering and their persistent demand compelled us to bring out the second edition of it. A few new chapters have been added. This has been done to add the astrological significance to the use of gems. Separate chapters have also been added regarding the astrological and numerological uses of gems. How they should be prescribed has been explained with the help of charts. Shri D.P. Saxena, a well-known astrologer and author of many book on astrology has done this for us. The second edition of the book as enriched by Shri D.P. Saxena’s contributed addition is now in the hands of our valued readers.
