    I have nothing but nice things to say about the ring's quality and brilliance. The people at Ziamond were also nice. The shipping just took too long.

    Shopping from this merchant has been a wonderful experience. I like their confirmations and the speed that its all done in. This is my second purchase and the ring is just as beautiful as my first one.

    I have wanted a trillion solitaire for so long. I ordered mine from Ziamond a few months back and I had to come back here to tell you how much I loved the whole experience from beginning to end. Great place to shop.
