MAC Neptune Nail Lacquer ($17.50 for 0.34 fl. oz.) is described as a “tarnished gold.” It’s a medium-dark, frosted aged gold with yellowy undertones and a green-ish/brown sheen. It reminded me a lot of MAC’s Old Gold pigment in nail polish form. It had fully opaque color in two coats, and it applied evenly and had very minimal brush strokes. Revlon Rose Gold (LE, $8.49) is much more muted. MAC Immortal Gold (LE, $16.00) is cooler-toned. ORLY Flare (P, $5.00) has larger shimmer, different finish. See comparison swatches / view dupes.

MAC Shimmerfish Nail Lacquer ($17.50 for 0.34 fl. oz.) is described as a “sparkling aluminum.” It’s an almost warm-toned silver with copper flecks of sparkle. It had a very metallic, high-shine finish that was reflective and satin at the dry down. It had full color coverage with two coats of polish, and it applied evenly and didn’t pool along the edges. The visible brush strokes were very minimal, which was a surprise. MAC Sinfully Sweet (LE, $16.00) has a yellower base. Zoya Jules (P, $9.00) is warmer, darker. See comparison swatches / view dupes.

MAC Submerged Nail Lacquer ($17.50 for 0.34 fl. oz.) is described as a “dark teal chrome.” It’s a medium-dark, navy blue with a teal micro-shimmer and flash. This one didn’t apply as nicely as the other two, as there were visible brush strokes and some unevenness, though the color coverage was opaque after two coats. Color Club First Looks (P) is much darker. China Glaze Deviantly Daring (LE, $7.50) is darker, more teal. See comparison swatches / view dupes.
