About Opal
Opal is a unique and stunning gemstone that is known for its vibrant play of colors. Here is a description of the physical characteristics of opal:
- Color: Opal can display a wide range of colors, including white, pink, orange, yellow, green, blue, purple, and black. The colors are caused by the diffraction of light, resulting in a colorful play of light that seems to move and shift as the gemstone is viewed from different angles.
- Transparency: Opal is typically translucent to opaque, meaning that some light can pass through it, but not enough to see through it completely.
- Hardness: Opal has a hardness of 5.5 to 6.5 on the Mohs scale, making it relatively soft compared to other gemstones. This means that it is more susceptible to scratches and damage.
- Lustre: Opal has a vitreous to waxy lustre, meaning that it can appear either shiny or dull depending on how it is cut and polished.
- Chemical composition: Opal is composed of hydrated silicon dioxide, which gives it its unique physical and optical properties.
Overall, opal’s distinctive color play, translucency, relative softness, and chemical composition make it a highly sought-after gemstone for jewelry and other decorative purposes.
