MAC has come out with several collections in the last few weeks and I picked up one of their matte polishes from the Riveting Collection. Studded is descibed as a "true silver pearl". To me it looks more like a silver with a touch of taupe and it's too sparkly to be a pearl, I would say it's more of a shimmer. It is matte, just more of a satin matte, not like the OPI mattes. More like OPI Suede. I think this is a really cool color, I just with it were a little more silver and darker-that would be a great matte silver!
