Overview of Labradorite
About
Labradorite is a member of the feldspar group and is known for its striking iridescence. Discovered in Labrador, Canada, the stone is also found in Finland, Madagascar, and Russia. Although its base colour is usually grey to dark grey, the brilliant play of colour has made labradorite a favourite in jewellery and crystal healing practices.

Treatments
Labradorite is usually untreated, though some lower-quality stones may undergo surface polishing to enhance their labradorescence.
Synthetics
There are no known synthetic versions of labradorite due to its complex internal structure and unique optical properties. However, glass and plastic imitations exist, often sold under different trade names.
Imitations
Imitations of labradorite are commonly made from glass or plastic materials, which attempt to replicate the stone’s iridescence but lack its natural depth and subtle variations in colour.
