This is a pretty, simply styled, 3 stone, band ring. The center stone is about 6mm or 1cttw., and the side stones are 5mm or 3/4cttw each. The band is quite thin, about a 1/16 of an inch. It's little too narrow to give a good balanced look to the size of the stones. Narrower than photographed.  The gram weight on the metal is 1.7 grams. A nicely weighted band would be about 3 grams.  The metal looks like highly polished silver. It doesn't appear to have a finish and may eventually need a good polish.

The stones are quite pretty and sparkling, but they do not look like diamond. Two of diamond's main visual characteristics  are shooting fire and brilliance. These don't have depth of fire, but they do sparkle like crazy.  To me, they don't even look like CZ. They certainly are not top graded, AAAAA CZ.  Those stones do rival diamond's appearance.  This ring appears like the Swarovski Crystal stud earrings I own.  For the 13 bucks I paid, I have no complaints.  I'm not returning and will definitely wear. It's not my favorite, but I like this ring okay.

This ring didn't need to look like diamond for me to like. The reasons I didn't like better has nothing to do with the stone's quality.  I would have really liked if the silver was heavier weight, the band were thicker, the side stones were 1/2cttw each, and if the silver had a rich plating.

For anyone wanting a diamond look in CZ, I recommend the Amazon. Com Collection of Platinum Plated CZ Rings. Those CZ rings look like flawless diamond. They are set like diamond, in heavy weight solid silver.  Of course, they're more money, but still reasonably priced.
