Title: Warning for other buyers
Review: I bought this ring just for ring size testing, so the quality is not a problem for me. But there are something about this ring and it's center stone that i think i should let other buyers know in advance. I highly doubt the material is CZ(Cubic Zirconia). Through carefully observing under the x30 jewelers scope, the refractive index of the center stone seems to be very low, about 1.6, which is very close to glass but not CZ. Typically, a CZ has a refractive index around 2.15. And diamond is 2.4. For those who does not know what i was talking about, let's put it this way: The center stone does not sparkle at all and it looks cloudy...I guess i wont return it since it is very cheap...
