Great news BB, i hope Andy gets your response soon PP.
When i had all my replies to all my treatments etc my yellow diamond pendant came back as irradiated and i spoke to Andy saying it is to honey coloured looking to be treated and i'm sure it was natural so he got back onto Thailand who said the colour scale for treated yellow diamonds run into the natural coloured yellow diamonds and some can look very similar, i still wasn't convinced so Andy asked the head buyer to track back where they were bought etc and eventually it came out they were indeed natural, which i'm pleased about but a bit miffed Thailand had the wrong details on it and when asked twice they still said they were treated, but i am greatful Andy sorted the information for me 3 times lol
