Metallic 08 has a stunning color range, shifting from a cool golden green to teal blue.
There are even a couple of shades similar to 08, including Missha HGR01 and PeriPera Metallic Green. These are both European/Asian brands, but can sometimes be found on Ebay.
The next day I decided to try layering Hard Candy Break up over one nail, a multichromatic glitter that shifts from gold to pink to blue depending on the light & color. The texture got a little weird though, kind of resembling fish scales, so I tried a glitter gradient with Sinful Colors Nail Junkie on the rest.
Although Golden Rose is a European brand (this lovely flew all the way from Poland!), we've been seeing a few metallic duochromes here, too. China Glaze is coming out with a line of six metallic duochromes this spring/summer. One looks very similar to GR 08, and another may be a dupe for Peridot. I hope these come out soon, because they all look amazing.
