by Nirasha » Mar 7, 2018 Hi, I'm going to exchange my centre Emerald diamond as it turned out to be not eye clean diamond. I have selected 3 diamonds according to my budget, can you please help me which is good. I had to go from colour F to G because of my budget but went to high clarity this time. Please help. I'm from London and seller has categorised all 3 diamonds as excellent cut.
