MAC Screaming Bright Studio Nail Lacquer ($12.00 for 0.34 fl. oz.) is described as a “super glitter gold [with a Pearl finish].” It’s a light-medium, slightly warm-toned gold with a pearly, slightly metallic, finish. It was very nearly opaque after two coats, and the consistency wasn’t too thick or too thin, so the polish spread evenly across the nail without a fuss. It dried down slightly faster than other shades in the range. There were very slightly visible brush strokes, but they weren’t noticeable from a normal viewing distance. NARS Gold Viper (LE, $20.00) is more metallic. L’Oreal The Statement Piece (LE, $6.99) is more glittery. Revlon Gold Coin (P, $4.99) is cooler-toned. Illamasqua Swinger (P, $17.00) is cooler-toned. Chanel Diwali (LE, $27.00) is darker. Obsessive Compulsive Cosmetics Cruising (P, $10.00) is darker, yellower. See comparison swatches / view dupes.

MAC Silver Dew Studio Nail Lacquer ($12.00 for 0.34 fl. oz.) is described as a “gold glitter base with multi-colored large glitter [with a Glitter finish].” It’s a glittering, white gold with larger multi-colored glitter. It was semi-sheer after two coats with noticeable translucency. It might be better as a top coat, though it’s almost too pigmented for that. Chanel Pearl Drop (LE, $27.00) was the closest I had in color, but it has such a different finish, so I wouldn’t consider them dupes.

MAC Formidable Studio Nail Lacquer ($12.00 for 0.34 fl. oz.) is described as a “teal green with pink multi-changing pearl [with a Pearl finish].” It’s a plummy purple base with iridescent shimmer that shifts from bluish-teal to fiery pink-plum. It’s semi-opaque after two coats (it’s really a three-coater, if you want nice results). The shimmer/pearl disperses fairly evenly, and it dries down to a lightly glossy finish. It had a slightly thinner consistency, but it didn’t pool along the edges or seem watery. Orly Galaxy Girl is very similar (thanks for the reminders!).
