I have a one karot diamond ring for sale. It has one half karot stone in the middle and ten.5 karot stones in the band. Which equates to one full karot. It's a size 5 but my jeweler said it would be no problem to have it resized. I have the receipt from where I got it new at Zales in the mall. I paid $1600. It looks brand new and I just had it cleaned. I will certainly take $700 OBO. You can call or text at 2 seven O two O 2 4 4 nine six. Thanks.
