Oh, dude, that stamp is like the secret code of the jewelry world. So, "r" stands for the manufacturer, "j" is the type of metal used (probably gold or silver), and "7" is the purity level. It's basically the jewelry version of a fancy ID card.
"S J" stamped on a ring could be the initials of the manufacturer or designer who made the ring. It could also represent a person's initials as a custom or personalized piece. Without more context, it is difficult to determine the exact meaning of the stamp.
Probably it means jewlerey or Jurassic ring.
Im not sure, but i have a ring stamped with an ARJ as well. It is a silver ring and i believe there is also a stamping of a face as well.

In the context of a ring, ( Jx ) typically refers to the product of an ideal ( J ) and an element ( x ) of the ring. This means that ( Jx ) consists of all elements that can be expressed as ( j \cdot x ), where ( j ) is any element in the ideal ( J ). Essentially, ( Jx ) is a submodule of the ring formed by scaling the ideal by the element ( x ).
It stands for J & C Ferrara jewelry co.
Jc is actually a stamp of the creators initial.
It is the initial of the designer or company. What is more important is the grade of gold or sliver.
There were two colors in the J and L ring: black and silver.
