Opal and tourmaline gemstones are both incredible artworks of nature. Their mixed composition allows them to appear in changing and different colors.
Let’s see how those colors dance in both gemstones:
Opal - The Ultimate Rainbow Stone
Opal boasts a unique appearance in the mineral world. The color spectrum of opal stone is a marvelous thing, and it’s unlike any other gemstone.
A single opal stone can display moving and changing patterns within its interior colors. Think of blue, green, purple, yellow, red, pink, or any other color combinations imaginable - all in one opal stone! Opal is uniquely classified as a mineraloid and is a hydrated form of silica which allows for this dance of colors to happen.
Please note that there are two classes of opal - precious and common. And only precious Opal can have this play of color.
Tourmaline - The Nature’s Artwork
Tourmaline is also a stone of multiple colors with a complex group of minerals in its composition. The main difference is that tourmaline doesn’t change colors; instead, it separates itself into different stones such as the famous black tourmaline.
Other tourmaline color variations include green, blue, yellow, pink, red, or colorless. Pink tourmaline for example is colored by the trace element manganese.
