Two things guarantee that our jewelry is made of gold or silver:
- 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.
- In addition, each jewel comes with a certificate of authenticity which includes the name of the person for whom the jewel was imprinted.
