257 Mermaid Blue gives you a navy blue and a wet-look gloss in one bottle. Blue is high contrast against most skin tones, so a clean cuticle line matters. DND DC lists it as a crystal blue reminiscent of clear waters. It is carried in the spring gel lacquer line-up at ND.
What you get in the bottle
- High-gloss finish: the DC gel dries to a glass-like shine that holds for the life of the set.
- Published wear you can quote: up to 21 days without chipping or peeling.
- The client leaves with the shade: DND DC 257 Mermaid Blue ships with a matching air-dry lacquer for touch-ups.
- Lamp-agnostic: cures under LED or UV.
- Gloss that holds: the cured finish stays high-shine for the life of the set as long as the top coat caps the free edge.

Which option should you add to the bag
On this page you are choosing between DND DC 257 Mermaid Blue in different formats. Gel Polish & Lacquer is the matched gel and lacquer pair, so the client can take the polish home in the same shade. Gel Polish Only is the gel bottle on its own, for salons that only run gel services. Lacquer Only is the air-dry lacquer on its own, no lamp needed. Gel & Lacquer + Dipping Powder is gel, lacquer and dip powder together, so one shade covers all three services. If you already stock base and top coat, the plain DND DC 257 Mermaid Blue duo is the sensible reorder. The bundled options exist for a new station or a second room that has nothing in it yet.
Storing the bottle
Keep DND DC 257 Mermaid Blue upright with the cap tight and out of direct sunlight, because daylight will start curing gel in a half-empty bottle. Wipe the neck before you close it so the cap does not seize. Pigment-heavy and glitter shades settle between services, so roll the bottle between your palms rather than shaking it, which puts bubbles in the first coat and shows up under the lamp.
DND DC 257 Mermaid Blue is stocked alongside the DND DC, DND and DIVA gel wall, the spring gel lacquer line-up and DC nail lacquers.
