Oparex® Nebula opal is created by mixing silica and resin. It results in a non-directional wave pattern that looks similar to nebula and aurora. The patterns and sizes of the waves are inconsistent, therefore, every piece is unique.
The color might be influenced by the level of the waves. The color chart is for reference only.
