I have found that the rj stamp is used by avon but i dont know anything else on what it means.
James Allen brand
Probably it means jewlerey or Jurassic ring.
It is the initials of the ring makers name
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.
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.
