Now treasured for its own sake, spinel is a favourite of gem dealers and collectors on account of its brilliance, hardness and wide range of spectacular colours. In addition to beautiful rich reds, spinel can be found in a range of gorgeous pastel shades of pink and purple. Of particular interest is a vivid hot pink with a tinge of orange mined in Burma. It is one of the most spectacular gemstone colours seen in any species at all. Spinel also comes in beautiful blue tones called cobalt spinel, but these are very, very rare.
