How Lab Created Opal is Made

Synthetic opal, also known as lab-created or man-made opal, is created through a controlled process that replicates the natural formation of opal. Our Lab created opal is known for its vivid colors and patterns.

While synthetic opal may have a similar appearance to natural opal, it's important to note that there are differences in terms of composition, structure, and value. Synthetic opals can offer an affordable and environmentally friendly alternative to natural opals. 

Also do not forget to consider that not all synthetic opal is created equally and may have different purposes. For example, our lab opal products are stabilized with polymer making it perfect for ring making and jewelry creations because it is less prone to cracking and crazing unlike natural opal. Polymer is a great stabilizer for this reasoning but it cannot be used in projects that require high levels of heat such as glassblowing. 

The Process

  • Silica Solution

The primary component of opal is silica (silicon dioxide). A silica solution is prepared by dissolving silica in water, typically with the addition of a stabilizing agent. The solution should have a similar composition to that of natural opal, which contains a high percentage of water.

  • Gel Formation

The silica solution is poured into a container and allowed to form a gel. This process may be sped up by adding a catalyst or adjusting the pH of the solution.

  • Coloration

To create the vibrant colors and patterns seen in Lab Opal, color pigments or metal salts can be added to the silica solution before gel formation. The addition of these pigments or salts results in the diffraction and interference of light, creating the characteristic play of color found in opal.

  • Aging and Polymerization

The gel is then allowed to age and polymerize. This is a crucial step that determines the final appearance and quality of the synthetic opal. During this stage, the silica molecules in the gel slowly bond together, forming a solid structure. This process can take anywhere from several months or up to a year, depending on the desired properties of the final product.

  • Drying and Hardening

Once the gel has aged sufficiently and the desired level of polymerization has been reached, the synthetic opal is dried slowly to remove any remaining water. This process should be carefully controlled, as rapid drying may cause the opal to crack or lose its structural integrity.

  • Cutting and Polishing

The fully dried synthetic opal can now be cut and polished into various shapes and sizes, just like natural opal. The cutting and polishing process can reveal the unique colors and patterns within the opal, making each piece visually stunning. Resulting in a lab created opal slab with endless possibilities. 

  • Final Form

Now the gemstone-like material can be cut, crushed, and drilled into many different forms. Lab created opal has been popularized in jewelry, ring making, woodworking, resin art, nail art, and so much more!
