What is Opal? (Opalescence Effect)
Opal is a unique mineraloid composed of hydrated amorphous silica (SiO₂ nH₂O), lacking the traditional crystal structure. It contains between 3% and 21% water.
Mohs: 5.5–6.5 • Formula: SiO₂ · nH₂O • Structure: Amorphous (Not Crystalline)
What makes opal valuable is the regular arrangement of microscopic silica spheres within it. This arrangement causes the light to be refracted and separated into spectral colors as it passes between the spheres. This phenomenon is called Opalescence and is the signature feature of Opal.
How to Create Color Play?
- Silica and Water: The main components of Opal.
- Diffraction: Silica spheres refract light and scatter it like a fan.
- Rainbow Effect: The size and arrangement of the spheres determines the observed color (small spheres give blue, large ones give red).
- Sources: The majority of world Opal production is from Australia (especially Black Opal).
Main Opal Varieties and Types
Opal is classified according to its base color (body color) and its value varies according to these colors.

Frequently Asked Questions (FAQ)
Why does opal "crazing"?
Opal contains a high percentage of water. It loses its water content in cases of extreme dryness, temperature change or exposure to direct sunlight. This rapid water loss causes the stone to shrink and create small cracks on its surface.
What is Doublet and Triplet Opal?
These are unnatural, processed opals. Doublet ; It is the bonding of a thin layer of Opal (usually cheap Potch Opal) onto a dark colored bedrock (obsidian or ironstone). Triplet is the addition of a protective transparent layer (quartz or plastic) to the upper surface in addition to these two layers.
What is the difference between Black Opal and White Opal?
The difference is in the body color of the stone. The body of Black Opal is dark gray or black, which makes the play of colors appear much more vibrant and bright. The body of White Opal is light or cream in color and the play of colors is softer.
Do I need to moisturize opal?
Wearing opal jewelry regularly (with body moisture and oil) can help prevent it from drying out. In very dry climates, storing the stone in an airtight plastic bag with damp cotton reduces the risk of desiccation. However, never leave it in water.
Where does the superstition that opal brings bad luck come from?
The popularization of this belief began when a character in Sir Walter Scott's 1829 novel "Anne of Geierstein" died when her opal was damaged. Before then, Opal was a symbol of luck and protection for thousands of years.
Does real Opal change color in water?
Hydrophane (water-absorbing) species, such as Ethiopian (Welo) Opal, become transparent and temporarily lose color play when immersed in water. It regains its color play after drying. Australian opals generally do not change color with water.
