Why Choose Our Ceramic Ring Blanks?

  • Classic & Modern Profile: The popular 8mm width offers a substantial, comfortable feel on the hand, while the polished black finish provides a contemporary look that makes inlay colors pop.
  • Exceptional Durability: Ceramic is renowned for its superior scratch resistance and strength, making it an ideal choice for everyday wear rings that maintain their pristine look.
  • Ready for Inlay: The interior of the wide 4mm channel is pre-scuffed to create a textured surface, ensuring a stronger, more reliable bond with your chosen adhesive and inlay material.
  • Comfort Fit Design: Features a rounded interior profile for a comfortable fit, making the finished ring enjoyable to wear all day.

Important Crafting Instructions

  • HANDLE WITH CARE: While extremely scratch-resistant, ceramic is a rigid material. It can crack or shatter if dropped on a hard surface.
  • AVOID OVER-EXPANDING: Do not use excessive force on a ring mandrel when sizing or working. Over-expansion can cause the ceramic to crack.
  • FINISH BY HAND: We recommend finishing your inlay by hand to maintain the pristine polished finish of the ceramic edges.

Creative Applications

  • Crushed Opal Rings: The 4mm channel is our most popular size for opal ring supplies. It provides the perfect canvas to create a bold and vibrant crushed opal inlay that truly stands out against the sleek black ceramic.
  • Wedding Bands: Create a durable and stylish wedding band by inlaying classic materials like wood, meteorite, or precious metal shavings.
  • Glow Rings: The wide channel is ideal for showcasing glow powders mixed with other materials, creating a ring with a stunning daytime look and a secret nighttime glow.

Typical ceramic band with wide sides and not the thin ones found from other suppliers. The wider sides make for a much nicer finished product.
