Hello everyone! And than you for your time in helping me identify this ring, in advance

! Ok, now about the ring: I have a 14K gold ring that I believe to be SW but people keep telling me it's not... But I am fairly certain that it is as I have seen it in a magazine, however can't remember which one

.... The ring is 14k (as previously said) it is shaped like a memory wire with a Tanzanite set in between. So the stone resides on top of your finger and you can see down through it, the 14k gold frame holds it in place on either side, there is also a 14k bridge that holds the 14k frame together and instead of screw it has diamonds on each side of it. Sounds complicate, but it's kind of like a chair. It has two sides and in between it has a seat cushion (in this case a Tanzanite stone) and it has a back that holds the two sides together, in this case the bridge with diamond stones. The bottom of the ring is flat and not round, so that when you stand it upright it actually stands. The sides of the ring where the d14K frame is are inlaid with Onyx and Opal.
And last but not least the ring does have a hallmark. It has two reversible R's jointed together. The first R is facing in the opposite direction, and the second R is facing the correct direction. It's a little difficult to research the hallmark due to the reversible R's. When I try to do a search for RR in 14k it just brings up so much stuff that is irrelevant.... Please help.
