Colorless Labradorite
Listing for one labradorite approximately 2" and up.
About
This white stone is a unique variety of labradorite sometimes called rainbow moonstone.
Most labradorite is dark grey but this variety is technically called colorless since, in geology, color is usually caused by impurities in the crystal structure.
Just like with most labradorite, when viewed at certain angles, a splash of bright colors can be seen on its surfaces. This is called labradorescence and is a result of internal, submicroscopic fractures in the layers that reflect light back and forth before dispersing it at different angles, which produce different colors.
The level of the iridescence depends on the precise chemical composition as well as the rate of cooling during formation, as the cooling is what causes the fractures.
Although it’s unofficially called rainbow moonstone, it’s technically not a moonstone, a mineral with a similar iridescence but a different chemical composition.
