Product Information

Use these 3mm pre-cut red opal hearts to create bold jewellery pieces or add vibrant detail to your fused glass designs.

Available in three sizes -

  • 15mm (15mm x 15mm)
  • 22mm (22mm x 22mm)
  • 35mm (35mm x 35mm).

For best results, tack fuse when using as embellishments to help retain their shape.

When double layered to 6mm for jewellery, they can be full fused.

Perfect for use with enamels, powders, frit and more, these ready-cut shapes save time while giving a clean, professional finish.

Due to the manufacturing process, small points may occasionally appear around the edges - these can be easily removed with a quick grind, diamond hand pad, sickle stone or grozing pliers
