Thanks again for your prompt reply, and sorry to bother you with another question. But I would like to quickly explain my situation, as I've now managed to get all the information and certificate that I needed back from the jewellery shop.
What happened is I bought an engagement ring a few months back, though at the time I was quite clueless as to what I was buying, but thought to just trust the jeweller's knowledge. The ring was said to have been the following diamond: Pear 8.49x5.82x3.80mm, 1.10 Carat, I, SI2, with very good polish, very good symmetry and faint blue fluorescence, with a WGI certificate which I was told was as good as a GIA.
But after taking the ring home something just didn't look right with the diamond and I could definitely see a very noticeable "line/crack" inside it. I therefore took it back and asked for a GIA report, which took almost 2 months and not surprisingly when it did arrive it was quite different to the WGI one; please see the attached picture.
However the jeweller has been extremely apologetic and offered to the rectify the situation now with this new diamond (the G colour 1.07ct which I originally asked about above).
1. I was therefore wondering whether you think I should accept this proposed change or whether I should ask for something better?
2. He claims this new diamond is worth a lot more than what I was originally promised (Pear 1.10ct described above), is that true?
