Jewelry, Gems, & Minerals/white gold ring

I also have a ring stamped "RSC" on the inner band. It's a man's ring, looks like gold to me, but I have no idea what it is, with a large RED gemstone-looking thing set into the center of the ring, and it also has 3 "diamond"-looking things set into each side of the ring (6 total), as if radiating from and perpendicular to the red center "stone".

I do not see any markings whatsoever on the ring anywhere, except for the RSC stamp.

So I thought maybe you had heard something about the "RSC" mark by now and could help me in determining if this is a pretty piece of cheap junk jewelry (which I enjoy as much as, if not more than fine jewelry, so I mean that in a NICE way!) OR if it's actually a valuable real gold and/or diamonds and/or ruby ring.

It feels nice and heavy to me, substantial, not thin or flimsy or bubblegum machine quality or anything. But I don't know much about that sort of thing, obviously.

Any comments?
