I agree, it's quite pretty!
Jewellery is not really my thing, even tho it's not uncommon in Italy for men to wear a ring or a gold chain necklace. I have a couple that I got as gifts when I was a boy, but I never actually wore them. I used to wear a leather cord necklace when I was younger (mostly in summer), but these days I don't really care about it.
I'm not big into jewelry either, and I have very little and wear even less. The ring in that picture is a pearl set in silver that my mother gave me, and I have a sapphire in silver that my dad gave me. I swap those out. I have a silver key I've worn around my neck for about 12 years, and I hardly ever wear other necklaces. I go through phases with earrings (I do have some amazing earrings, though: silver TARDISes, silver fibonacci spirals, Scrabble tile WTF/OMG earrings, etc). I just find too much jewelry feels in the way.
On men I don't really find too much jewelry attractive. I do like a piece or two here and there: I like rings -- simple, thick bands, not bling. I like a nice watch. Maybe an earring on the right guy. Maybe a bracelet on the right guy.
