Ah! Nice that you can focus mainly on 1 metal!
I was primarily YG... lol. But now i am inclined towards WG -.- but i realise somehow that WG has many shades, some more grey like Cartier and while i like some of their design, i dont like the color of most of their WG items..
There are times where i wear light coloured or floral clothes that i will lean towards my YG pieces, so i am having to spilt my collection both ways. LoL. Abit annoyed. Like i always end up getting 2 pieces of the same thing. E.g. perlee rings, i have YG then now WG. Coco crush ring, YG pave then WG plain, Cartier c d cartier necklace in WG, then the 1895 necklace in YG! Ugh. O.o hahaha. In a way they are duplicated but i try to vary where possible.
