    I ordered the 1.5 ct. radiant cut. I was amazed at the fire it has. No one knows my diamond is not real. I have it in a real setting surrounded by 1.5 carat of diamonds and there is no difference. I am definitely going to order again, next time a pair of earrings. Ziamond is a hit in my house!!!

    I was extremely curious about the quality of Ziamond, so I purchased a loose stone, brilliant cut. The quality and brilliance are beautiful, and well worth the money. I am going to have it set in a pendant for my daughter. I am looking forward to ordering other pieces now that I have seen how great the quality is. Dee Dee

    After working in the jewelry industry for about 5 years and learning quite a bit about diamonds, I had my doubts about buying cubic zirconia....but WOW...I'm sold on ZIAMOND. This stone is beautiful! I will definitely be back!
