Introduction to Opal Stone
Opal is one of the most captivating gemstones in the world. Its vibrant flashes of color, called play-of-color, make it unique and highly sought after by jewelers, collectors, and metaphysical practitioners. At OneStep Gems, we offer natural, ethically sourced opal stones that reflect both beauty and individuality.
Whether you’re drawn to opals for their mystic energies or their aesthetic brilliance, this guide will help you understand everything about this phenomenal gem.
What Is an Opal Stone?
An opal stone is a hydrated amorphous form of silica with a water content that ranges between 3% and 21%. Unlike other gemstones that are crystalline, opal is mineraloid—meaning it does not have a defined crystal structure. Its internal composition allows it to diffract light, creating the iconic kaleidoscope-like colors opal is known for.
Scientific Facts
- Composition: SiO₂·nH₂O
- Hardness: 5.5 – 6.5 on the Mohs scale
- Transparency: Translucent to opaque
- Common Origins: Australia, Ethiopia, Brazil, Mexico, and the USA
The History and Legacy of Opals
Opals have been revered for thousands of years. The ancient Romans valued them above all other gems and associated them with purity and hope. The Greeks believed opals gave the gift of prophecy and protection from disease. In Arabic legends, opals were thought to fall from the heavens in flashes of lightning.
During the Middle Ages, opals were known as “ophthalmios” or “eye stone” due to the belief that they could cure eye diseases and maintain good eyesight.

How to Identify a Genuine Opal Stone
At OneStep Gems, we deal only in authentic, natural opals. If you’re shopping elsewhere, here are some tips to identify genuine opal:
- Natural opals often have irregularities and layered color patterns
- Synthetic opals may display a "snake-skin" or too-perfect appearance
- Real opals feel slightly cooler and heavier than imitations
- Examine the back: doublets or triplets will show a different material underneath
How to Care for an Opal Stone
Opals are relatively soft and require delicate handling.
-
Avoid exposing to direct heat or sunlight for extended periods
-
Keep away from water if the opal is hydrophane (such as Ethiopian opal)
-
Store separately to avoid scratches

Clean with a soft, damp cloth—never use harsh chemicals or ultrasonic cleaners
