All About Tourmaline Engagement Rings

Tourmaline is mined mostly in the United States, Brazil, Africa, Afghanistan and Sri Lanka and comes in different colors depending on which mineral makes its base. Iron-rich tourmalines come in typically dark brown or crown colors, while the ones most used in engagement rings are usually made of lithium and the brown or yellow varieties are rich in magnesium. There are also other forms of tourmaline that have two colors, one at each ends and there are others which change colors based on the angle of light they receive.
These different types of tourmalines are known by specific names. There are the ‘schorls’, which are iron-rich tourmaline’s.
