Opal is the birthstone that represents the month April.

Opal is the world’s most popular phenomenal gem. Many cultures have credited opal with supernatural origins and powers. Arabic legends say it falls from the heavens in flashes of lightning. The ancient Greeks believed opals gave their owners the gift of prophecy and guarded them from diseases. Europeans have long considered the gem a symbol of hope, purity and truth.

Why are we in love with opal?

  1. Formation: When opal formed, silica gel filled crevices in rock. As water evaporates, the silica is deposited in the form of tiny spheres.
  2. Interaction with Light: Opal’s flashing play-of-colour is caused by diffraction of light by silica spheres stacked like tiny Ping-Pong balls in a box.
  3. Unique: Opal’s arrays of silica form a fantastic variety of patterns and colours. No two opals are exactly like one another.

Opal is sometimes thought of to be a gem worn by the older lady, but today many popular celebrities such as Taylor Swift in the public eye are showing us that anyone can rock it, and just how beautiful these gems can be.
