Synthetic Opal or Lab Created Opal Meaning

The discovery of the ordered spherical structure of the precious opal led to its synthesis by Pierre Gilson in 1974. The resulting material differs from natural opal in its regularity.

Under magnification, colored patches can be seen on the lizard's skin or wire mesh pattern. In addition, synthetic opals do not fluoresce under ultraviolet light. Synthetics also usually have a lower density. And they are often very porous.

However, most synthetic materials are more correctly called opal imitations. They contain substances that are not found in natural opal. For example, plastic stabilizers. Artificial opals in vintage jewelry. Often this is foil glass. Also a glass-based slocum. Or later plastics.

Other studies of microporous structures have yielded highly ordered materials. It has similar optical properties to opals. And they were used in cosmetics.

Artificial opal. Slocum Stone

Slocum, sometimes sold as opal slocum, is an early opal that mimics opal. It was popular for a short time before the advent of synthetics. And cheaper simulators. It is a silicate glass containing trace amounts of sodium, including magnesium, aluminum and titanium.

We can find it in several base colors. Very thin layers of metallic film create artificial opalescence. Estimated to be 30 nanometers thick in translucent flakes. This gives the effect of thin film interference. The petals themselves give color along with the dye in the glass base.

Bubbles and swirls, typical of glass, are also typical inclusions. We see it enlarged. In later examples, when viewed from the side, the overgrown layering is visible.

Opalite

Opalite is the trade name for man-made opal glass, but it is misleading as it is also the name of some kind of natural opal. And various imitations of opal. Other names for this glass product are argenon, as well as sea opal, opal moonstone, and other similar names. It is also used to promote impure varieties of common opal in different colors.

FAQ

Are laboratory opals valuable?

As well as other artificial stones. It does not matter

How do you know if artificial opals are real?

Most real hard opals have bumps in this area, curved or uneven due to their natural formation. In contrast, the artificial stone will be perfectly flat as the two parts are flattened so that they can be glued together. Be especially careful if the opal is embedded in a piece of jewelry and you cannot see the back or side of it.

Is synthetic black opal stronger?

Synthetic opal is no stronger than natural opal, although synthetic opal is more flexible and actually softer to cut than natural opal. Opal has a hardness of approximately 6.5 on the Mohs scale. It is slightly harder than glass. Definitely stronger than emerald and stronger than pearl.

What is the difference between a real opal and a fake?

Most real hard opals have bumps in this area, curved or uneven due to their natural formation, while fake stone will be perfectly flat as the two pieces are flattened to allow them to be glued together. Be especially careful if the opal is embedded in a piece of jewelry and you cannot see the back or side of it.

Can synthetic opal get wet?

Yes. Synthetic opal can get wet. The only thing it does not resist is heat, even at low temperatures, with an ordinary lighter.
