Commitment and Services

Establishing that each jewel must have punches 2 stamps with contrast, first the Official Laboratory code and the gold law, and second contrast the manufacturer's code. Both stamps are stamped by the Official Authorized Verification and Contrasting Laboratories of Spanish Precious Metals.

Salvador Muñoz Joyero undertakes that the diamonds comply with the characteristics and have passed the quality controls and for this he issues a certificate with the purchase of the jewels that contain diamonds or precious stones.

In the quality certificates we specify the following characteristics:

• The shape of the carving.
• The weight of the diamond in carats.
• Its color grade
• Its degree of purity
• The date of issuance of the certificate.
