18k White Gold Natural Diamond Solitaire Pendant.  Marked 750 on the bail which is another way to indicate 18k. The diamond is beautiful I can't get a picture to do it justice.  It's eye clean, bright and colorful in the right light.  It's a natural diamond, guaranteed.   I bought this from a reputable seller and tested it as well.  I'm unsure the ctw, I think it's 0.15ct.  it could be anywhere from .10- .20  unsure of exact size . Please view photos I have it next to an inch side and a cm side of a ruler.  Weight pictured above.  Please read and view all photos.  Ask questions if you have any, returns are not accepted
