Re: Rain scents
DS & Durga had one called Pale Grey Mountain, Small Black Lake that was pretty stony but you'll have to dig around for it online as it's been discontinued.
Frederic Malle’s Angeliques Sous La Pluie definitely has a bit sparkling rain to it.
Black March by CB I Hate Perfume gets mentioned a lot but I've never smelled it.
- There's also CLEAN - RainI can't remember the smell of this but it looks more watery floral than rain to me.
