Green and pink tourmaline

The word "tourmaline" comes from the Sinhalese "turmali", meaning "stone with mixed colours". This gemstone exists in almost every colour of the rainbow and has a high hardness, which makes it durable and scratch-resistant. Celine uses every colour variety of tourmaline in her collections.

Also rare is rubellite, a beautiful intense pink-red tourmaline. It is sometimes confused with ruby but has a pinker undertone. Indicolite, in turn, is a blue variety of tourmaline.

Blue Paraíba tourmaline

Paraíba tourmaline is a rare gemstone known for its striking neon blue to green colours. These colours are caused by the presence of copper and manganese, and sometimes iron.

Its name comes from the Paraíba region in Brazil, where the stone was first discovered in the late 1980s. Similar gems were later also found in Mozambique and Nigeria. Because of their limited availability, Paraíba gems are mainly used in high-end jewellery.
