The OPI Designer Series for fall 2014 introduces us to a new formula called Polished Quartz.
Polished Quartz has a semi-matte finish and major sparkle. The Designer Series line now has 11 shades including these two additions called DS Tourmaline and DS Titatnium. Since these have a semi-matte finish they are made to be worn without a top coat, but if you wanted to add some shine, by all means, please do!
