Love hematite, it's pretty much the only thing I can wear for an extended period without it breaking xD

If it's not some magical property it could just be that they're pretty and sparkly and not something you can just walk into a shop and buy so people are probably initially just wanting to comment on how pretty it is and BANG conversation XD

The weirdest thing can be conversation starters though. My mum bought me a shirt with some Mozart (I think) score printed on it. I got stopped by so many random people wanting to know if I was a musician because they were and recognised it, or simply commenting that that particular piece was really difficult to play XD I should actually listen to the song in question as I do probably know it but otherwise to date I don't recognise the name of it and just like the pattern of the music notes XD
