gold or platinum or silver
Ive looked on jewelry websites and it seems that the most expensive jewelry has a lot of silver-gold or diamonds or both in them.
Gold.
If you mean the soap there is no metal used.
copper is used as base metal in gold jewelry
Platinum is used but is quite expensive so sometimes white gold is use. Other options are yellow gold and rose gold.
PMS on jewelry typically stands for Precious Metal Stamp, indicating the type of metal used in the piece, such as gold or silver. It helps verify the authenticity and quality of the metal used in the jewelry.
The Da Vinci Jewelry I know of is considered fine jewelry and since fine jewelry needs special care I will explain how to clean fine jewelry which will be good for all types of jewelry. A solution of half Mr. Clean and water with a small amount of ammonia can be used to clean all types of fine jewelry. Soak the jewelry piece for 15 seconds then rinse in cold water and dry. This solution is used by many jewelry stores I know of and they use it for all types of jewelry including inexpensive jewelry, fine jewelry, and even opals, and emeralds. A bowl can be used, but an ultrasonic is better. Repeat if the piece is extra dirty.

copper?
Silver.
PI represents the platinum with Iridium setting of the jewelry. It is mostly used in fine jewelry. The ring might be a fine jewelry.
