I received my ring yesterday. This is my engagement ring. and I really wanted to have the final say on the design, stone and everything. I decided to go with eng812 and I had it cast in a rose gold setting. I decided to go with a 1 carat stone. I was really torn about the Forever One, but I went without it. The process of casting and building the ring took about two weeks. When I received my package i felt like I was a wild animal trying to open it up.... I was nervous that maybe my finger won't fit or maybe the stone will pick up the rose gold tone. It was quite the opposite. The size was done perfectly, which is saying a lot due to my small 3.5 size. The center stone had what seemed to be a very faint cast to it, but oddly enought I was only to pick up on it once. It was so faint I feel like I was imagining it. I was proposed to with this ring and I have been glued to it ever since, I can't take my eyes off it. I am going along with the gig that it's a diamond but only because I do not feel like hearing anyone's opinion. Not one person has questioned the stone. In my opinion the stone is very similar to that of a very well/ perfectly cut diamond. I have a diamond ring and side by side they both have brilliant rainbows of color. I believe the only difference is maybe when using flash photography, but I honestly love the look of it in every lighting.
