Majorca Pearls are not Natural or Cultured Pearls by: Yvonne
Good Morning Manuela
Majorica Pearls or Majorca Pearls are the grandam of Imitation Pearls. They are not Cultured Pearls or Natural pearls. The interior of the Majorica pearl is filled with a wax sustance to guarantee the heft and strength, this is why your earrings feel heavy. They are "pearlized" with fish scales to obtain their beauty and lustre.
