Item Reviews

I just thought this setting was so interesting when my fiance and I were looking at engagement rings. When we first started looking, I thought I wanted something more traditional but after about 20 seconds looking at the ring rotate, I became more and more intrigued. I fell quickly in love with this setting, as I had never seen anything like it, and strongly hinted to my boyfriend that I wanted a ring that was unlike everyone else`s. Well, he got the hint and now I get to look at this piece of STUNNING jewelry on my hand every day! Thanks James Allen!

I love tension settings and marquise diamonds, but was having trouble finding combinations that could accomodate both. I was thrilled when I saw this setting and it turned out just like I imagined it would. I`m glad I didn`t give up the search and that I found James Allen!

I purchased this ring on a whim. I just had to see it! My fianc?© loves it! She wanted unique and she got it. I also purchased a .78 marquise to go in the setting and it looks huge. I was trying to get a very unique ring and was very pleased with this setting!
