Prisilla's 4 CT Asscher Cut CZ Engagement Ring Wear 4 CT Asscher Cut CZ Engagement Ring if you want serious celebrity style. Thin rhodium plated sterling silver band has pave set round CZs that extend partially down each side. Stunning 4 carat asscher cut CZ center stone is prong set and slightly raised above the band. This isn't our most believable fake diamond (unless you can afford an actual 4 carat rock!), but it might just be one of our most beautiful fake diamonds...
