Exceptional large and giant crystals exceeding 1 m belong to the most spectacular and impressive formations of the mineral kingdom, which fill many people with wonder and enthusiasm. As early as 1900 various famous mineralogists tried to compile and document the occurences of giant crystals and explain their genesis. Nevertheless the readily available scientific data on giant crystals remained limited and gathering the widely scattered information was and still is a tedious work.

The giant crystal project aims at using the modern communication ways to gather and accumulate as much information about giant crystals and giant mineral aggregates as possible and to present the findings on this website. To enable many people to share this knowledge, english was choosen as language for this website, though the main author is of german mother language.

Large and giant crystals are fragile and often unique creations of our nature, which deserve our special attention and protection, to keep them for posterity and our children. Please help to protect these marvellous creations of our mineral kingdom.
