While most other necklaces are simply referred to by their physical measurement, strings of pearls
have their own set of names that characterize the pearls based on where they hang when worn
around the neck. The names for pearl necklaces are:
  • Choker - Nestles at the base of the neck
  • Collar - Rests directly against the throat - can be multiple strands
  • Princess - Comes down to or just below the collarbone
  • Matinee - Falls just above the breasts
  • Opera - Long enough to reach the breastbone or sternum
  • Rope - Any length that falls down further than an opera

Necklaces can also be classified as uniform, where all the pearls are the same size, graduated,
where the pearls are arranged in size from large in the centre to smaller at the ends, or tin cup,
where pearls are generally the same size, but separated by lengths of chain or wire.
Pearl Sizes
Welcome to
The House of Pearls
Pearls are measured in millimeters at their diameter. The size
of the oyster directly affects the size of the pearl.  Larger
mollusks create larger pearls. It is also more likely that a
larger pearl will also show more surface defects.
5mm       6mm       7mm        8mm          9mm         10mm         12mm               13mm                14mm  
The sizes of pearls that are cultured today are determined by the size
of the mollusk in which they are cultured.    The chart below shows the
sizes of the mollusks and the pearl sizes that they produce.  Larger
sizes do occur but are considered rare
