The gemstone peridot, which is a variety of the mineral olivine, can exhibit different color variations due to variations in its chemical composition and the presence of trace elements.
The green color of peridot is caused by the presence of iron within the crystal structure of the gemstone. However, the specific shade of green can vary depending on the amount of iron present and the way it is distributed within the crystal lattice.
Peridot can range in color from a yellowish-green to a deep olive green. The intensity and hue of the green can be influenced by factors such as the amount of iron, the presence of other trace elements, and the quality of the stone. Higher iron content generally results in a deeper green color.
Take a look at the different peridot colors below:
In some cases, peridot may also exhibit a brownish or yellowish tint due to the presence of impurities or inclusions. These impurities can affect the overall color and clarity of the stone, making it appear less pure green. However, peridot is most highly valued when it displays a pure and vibrant green hue.
It’s worth noting that the color of peridot can also be influenced by lighting conditions. Different light sources, such as natural daylight or artificial light, may emphasize different aspects of the stone’s color, leading to variations in appearance.
Other contributing factors that can affect color:
- Natural or Synthetic Gemstones
- Size and Shape
- Polished or Rough Gems
- The Setting or Mounting
- The Origin or Location of the Peridot Mined
So you see, the various color variations of peridot are primarily attributed to differences in its chemical composition, particularly the amount and distribution of iron within the crystal structure. Other factors, such as trace elements and impurities, can also contribute to variations in color.
The most desirable peridot gemstones exhibit a pure and vibrant green hue, while factors like lighting conditions can influence their appearance.
