A Beginner’s Guide to Edison Pearls

Edison pearls are a unique type of freshwater cultured pearl that have gained popularity in recent years. In this beginner’s guide, we will cover everything you need to know about these lustrous gems – from origin and features to selection tips.

 Edison pearls originate from Zhejiang Province in China. They are a relatively new pearl variety cultivated using techniques inspired by saltwater pearl farming.

 With diameters exceeding 10mm, Edison pearls are considered large. A 13mm pearl typically yields a 5mm thick half-drilled pearl.

 Edison pearls display a diverse range of hues including white, creamy yellow, purple, pinkish-purple, orange and more.


  • Round shape
  • Large size
  • Diverse colors
  • Relatively thick nacre
  • Surface growth lines

 Edison pearls are graded on size, luster, shape and imperfections. Larger, brighter, rounder pearls with fewer flaws fetch higher prices. Prioritize as follows within budget:

  1. Luster – Brighter pearls are more valuable
  2. Size – Bigger pearls are rarer and pricier
  3. Shape – Rounder pearls are more desirable
  4. Imperfections – Minor flaws are expected

 Use these tips to select the perfect Edison pearl. Size and shine come first, but a flaw here or there makes each pearl uniquely charming.
