Here is a nice Aragonite from Castile-La Mancha, Spain.
The size is 51x35x31 mm (height, length, width) and it is 122 grams.
 
The crystal is a perfectcyclic-twinned pseudohexagonal crystal.
The color ranges from white to purple. Some small nicks on the edges, but besides from that no damages.

I purchased this crystal a mineral shop about 30 years ago, and have kept it in my collection ever since then.
