Grapefruit, you say?
Aqua Allegoria Pampelune by Guerlain. If you live near a Sephora, check it out in the women's section.
Also, for metallic, Silver Mountain Water is most definitely a primo choice. Chrome is pretty good metallic-wise IMO. I'd even go as far as to say Eau de Grey Flannel (blue bottle), which can be found for very cheap at TJ Maxx/Marshall's.
