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.

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.

there is a square with a "j∆"
J triangle L is an old symbol used in jewlery to let the receiver of the metals know that the giver is cheap, and does not love that person whom he is giving them to. In fact the J stands for jack and the triangle mean threesome or no commitment and the L is a Latin term meaning gold is too much so here is this ring made of crap.
