OPI GelColor Gel Nail Polish Black Onyx — Opaque Dark Black Crème, LED-Cure, Vegan

OPI GelColor Black Onyx is a salon-grade, opaque dark-black crème gel polish that cures quickly for glossy, long-wearing nails.

Richly pigmented and formulated for professional results, this OPI GelColor shade gives deep black coverage with a reflective crème finish. Built on OPI's Intelli-Gel Technology, Black Onyx is designed to lay down smoothly, self-level for a streak-free look, and cure fast under an LED lamp so your manicure is smudge-resistant in seconds. The formula is vegan and HEMA-free, offering a salon-quality option without animal-derived ingredients.

How long will Black Onyx last on natural nails?

When applied and cured correctly by a trained nail technician, OPI GelColor Black Onyx is engineered to provide up to three weeks of wear with minimal chipping. Longevity depends on proper prep, application, and aftercare.

• Up to three weeks of chip-resistant color with correct application
• Self-leveling formula helps reduce tip wear and edge lifting
• Best results when cured with a compatible LED lamp like OPI Star Light

How quickly does it dry and how is it cured?

Black Onyx cures rapidly under LED light, offering a near-instant dry finish that prevents smudging. The Intelli-Gel base allows a consistent cure so color and shine develop evenly across each nail.

• Cures in approximately 30 seconds under the OPI Star Light LED lamp
• Instant smudge-proof surface after lamp cure
• Compatible with most professional LED curing lamps for efficient salon service

What makes the application easy for nail technicians and home users?

The formula includes a rounded Intelli-Brush and self-leveling properties that simplify brush strokes and coverage. That means fewer passes to reach full opacity and a smoother finish for nail art or classic looks.

• Rounded Intelli-Brush provides controlled, even strokes
• Highly pigmented for one- to two-coat opacity on most nails
• Self-leveling gel reduces visible brush marks for a salon-smooth surface

How is the polish removed and is it gentle on nails?

OPI GelColor Black Onyx is formulated for professional soak-off removal, which lifts the gel without aggressive filing when performed correctly. Proper removal helps preserve the natural nail plate and maintain overall nail health.

• Soaks off in approximately 15 minutes with standard gel removal protocol
• Designed to be removed without excessive scraping when done by a technician
• Vegan and HEMA-free formulation reduces exposure to certain ingredients for sensitive clients

Who is this for? OPI GelColor Black Onyx is aimed at salon professionals and experienced at-home gel users who want a deep, even black polish that delivers quick curing, high shine, and multi-week wear. It’s an excellent choice for clients seeking a classic, bold color for manicures, nail art backgrounds, or durable long-wear finishes, and for technicians looking for a predictable, easy-to-apply gel polish that performs consistently.
