Brazilian Smoky Quartz Towers with Rainbows

1:  .23Lb 2:  .63Lb 3:  1.16Lb 4:  2.09Lb   Smoky quartz, a popular variety of quartz, can develop rainbows due to its internal structure and the presence of tiny imperfections or inclusions within the crystal. Rainbows in smoky quartz, also known as "inclusions rainbows," are caused by the scattering and refraction of light as it interacts with these microscopic imperfections. When light passes through the crystal and encounters these inclusions, it gets diffracted, creating a beautiful play of colors similar to a rainbow.
