Caviar beads are tiny glass spheres, approximately 1mm in size, used for decorating fingernails in nail art.

To apply caviar beads to your nails, simply add them to your uncured gel or nail glue
individually using a pick up tool. Or sprinkle them onto the gel or glue for a full nail of beads. Cure the nail using a UV or LED lamp to set the caviar beads into place.

Caviar beads are used to create tiny intricate designs on the nail, fill any gaps in between nail embellishments, or to outline a design giving it a neater overall finish.

Micro caviar beads are another term for caviar beads that are even smaller in size, generally less than 1mm.

Caviar beads can range from 0.8mm up to 3mm, however the most common size for nail art is 1mm.
