Answer 2

"B2" stamped in a ring typically refers to the type of metal used in the ring. In this case, "B2" likely denotes that the ring is made of a metal alloy containing a combination of metals that fall under the B2 category. The specific composition of the B2 alloy can vary, but it is commonly used in jewelry making for its durability and resistance to corrosion.
