How can I be sure it is real solid gold or silver?

Two things guarantee that our jewelry is made of gold or silver:

  1. Each Penta Power jewel contains a hallmark : “Au 750” for the gold and “Ag 925” for the silver Jewels. The symbol “Au” refers to the chemical element gold, just as “Ag” indicates the chemical element silver.

  2. In addition, each jewel comes with a certificate of authenticity which includes the name of the person for whom the jewel was imprinted.
