Labradorite

labradorite gemstone jewellery
Labradorite is a variety of plagioclase feldspar found in igneous rocks and is characterized by brilliant colours although the surface of Labradorite is usually grey or almost black.
Like Moonstone, labradorite displays a shiller of iridescent colour called labradorescence which is the result of lamellar intergrowths inside the crystal. These intergrowths result from compatible chemistries at high temperatures becoming incompatible at lower temperatures and thus separating and layering.

rose quartz gemstone jewellery
The pale pink colour of quartz, which can range from transparent to translucent, is known as rose quartz.
