I found a diamond that I am interested in and my girlfriend really likes. It is a 1.5 E SI2 EX cut with VG polish with a GIA report of 1245115810. It is a great looking diamond and eye clean just want to make sure I am paying a fair price. It was initially 13250 but down to 12500. It has medium blue florescence and not sure if that is an issue. Any help if this is a good price would be appreciated.
