I have and love the interlocking circles necklace in size small. It's a Tiffany piece that says "Tiffany" on it but the writing doesn't scream out at you. It doesn't lay flat like other necklaces due to the way the circles are joined. They move around and make a soft tinkling sound that I love. It's not a "static" design. Some people would hate that. Just something I thought I should point out since the other two necklaces you picked out are pendants and will lay one way all the time. I also noticed you linked to the medium size. There's an older thread on here that has good pictures of both sizes (one person is even wearing both sizes at the same time). The medium definately has a bigger presence.
