  • All round: When measuring with a millimeter gauge, it does not vary more than 1/10th of a millimeter
  • Mostly round: Measurement with a millimeter gauge does not vary more than 2/10th of a millimeter. To the naked eye it will resemble all round
  • Slightly off round: To the naked eye the shape appears slightly off round
  • Off round: To the naked eye the pearl is off round (oval, or squatty in shape) but still symmetrical
  • Semi-Baroque: To the naked eye the pearl is misshapen and appears to come to a point (i.e. tear drop shaped)
  • Baroque: To the naked eye the pearl is freeform. No symmetry, and shape of pearl is very irregular
