KOSINER gold and silver flat back base collection, 14K solid gold, waterproof, not plated

KOSINER 14K Solid Gold Multi-Sized Flat Back Base

$44.99
A striking black coffin stud crafted in 14K solid gold, bringing a subtle gothic edge to your everyday piercing stack.

Dark geometry, refined in gold. The Black Coffin Flat Back Stud features a faceted natural black agate stone cut into an elongated coffin-inspired silhouette and framed in genuine 14K solid gold. Small star details along the gold setting add a subtle celestial accent, balancing gothic influence with polished fine-jewelry craftsmanship. Paired with a 6mm titanium internally threaded flat back post, this piece delivers a bold focal point while remaining streamlined enough for everyday helix, cartilage, tragus, or lobe styling.

  • 14K Solid Gold Front — genuine gold, never plated
  • Natural Black Agate — deep black tone with a faceted finish
  • Coffin-Inspired Silhouette for a refined gothic statement
  • 6mm Titanium Flat Back Post for lightweight, durable wear
  • Internally Threaded Closure for secure, smooth insertion

Tip: The elongated coffin silhouette makes a strong focal point on the helix or upper lobe. Style it vertically for a sharper look, or rotate it slightly to create a more directional curated ear.

Design Details

The faceted black agate creates depth through light and shadow, while the polished 14K gold frame softens the darker silhouette. Tiny star details introduce a subtle celestial element, giving the piece a light punk character that feels distinctive without becoming overly theatrical.

Styling Tips

Pair it with polished 14K gold hoops, Ankh Cross studs, geometric flat backs, or other black-stone jewelry for a refined gothic ear stack. For more contrast, combine the deep black agate with clear diamond or zircon pieces to create a balanced mix of darkness and light.

Jewelry Care

Crafted with a genuine 14K solid gold front, natural black agate, and titanium flat back post. Clean gently with warm water and mild soap, then pat dry with a soft cloth. Avoid abrasive cleaners, harsh chemicals, and impact against hard surfaces to help protect the polished stone and gold setting.

Quality Promise

Each KOSINER Black Coffin stud combines genuine 14K solid gold, carefully set natural black agate, and a durable titanium internally threaded post. Designed for secure everyday piercing wear, it brings fine-jewelry materials together with a distinctive modern gothic silhouette.
