I finally got my girlfriends engagement ring on Monday and had it appraised today. I just wanted to say thanks to everyone posting on here with all the useful information. I didn''t register because I found most questions I had were already posted and answered by other people. I did use this website a lot and even got a discount by using the Pricescope name so I only felt it fair to say thank you.
The ring is in 18kt gold, with a 0.92ct Princess cut, F, SI1 centre, with 2 side stones and 8 channel set princess cut diamonds on the sides.
