Zoya Rikki Nail Lacquer ($8.00 for 0.50 fl. oz.) is described as a “full-coverage, fern green foil metallic.” It’s a sumbdued, medium green with almost cool undertones paired with muted, golden shimmer. It has a foiled, metallic finish. China Glaze Unpredictable is metallic but also a duochrome so it flashes from green to bluish-teal. Zoya Apple is brighter. See comparison swatches.
