Updated review: I finally got my ring back from sizing. I asked to have it cut down to a size "6" and it is now a "5 3/4" which is ok. I'm changing my review top 1 star for the sole reason that I'm tired of NOT getting the size I ordered. This is the 3rd Charles & Colvard ring I have ordered in the past 6 months and NONE received were a size "6" like I ordered. Updated review::The first one I sized at a 6 14, took a pic of the ring on the sizing wand and I sent it back to be sized and was told the ring was a size 6 on thier wand. The 1 7/8cttw I received a couple of weeks ago showed being a "6 1/2" on my wand so I took it to *** who also sized it at a 6 1/2!! None of the jewelry stores will touch this ring to make it the correct size. I am beyond as pissed as this is my engagement ring and have to wear a sizer to make it fit! This is my 3rd Charles & Colvard Moissanite solitaire ring. I own a 1/2cttw, 7/8cttw and now this 1 7/8cttw solitaire ring. The color is the same of the 1cttw heart shaped diamond I owned years ago and Paid over *** for but this ring is so much prettier! The sparkle is incredible especially in the sunlight and yes, the stone is 8mm in size. The only issue I have with the ring is, I ordered a size 6 but it measures a 6.5 on the metal ring sizer wand. I will end up having to get it sized to the size 6 I originally ordered.
