Hi and welcome to the forum.
Your image of the hallmark is not particularly clear so I am not 100% certain that my identification of it is correct. I seem to see a Birmingham hallmark with a Convention Mark, 750 for 18K gold, the Birmingham anchor and the date letter "e" for 2004. It will not be possible to identify the sponsor/maker, CPM, without contacting the Birmingham Assay Office directly as there are no published references for modern sponsors' marks. I do not know the significance of the sunburst symbol.
