Pieces of blue Aragonite from England.
Aragonite is also known as tchazar crystal and tufa. This carbonate gemstone is usually colorless or white in color.
However, there are Aragonite stones that have subdued shades of blue, green, brown, orange, yellow, pink and red.
It was discovered in 1978 in the Aragon River in Spain, and this is how it got its name. Aragonite is usually mined in the USA, Poland, Italy, Germany, Austria, the UK, France, Spain, Namibia, Morocco, and Mexico.
The old iron mines at Frizington, Cumbria, England; as well as the locality of Vitosov, Moravia, Czech Republic; have both been good specimen producers.
