NB :

  • The streak or « powder color » in gemology is the process used to confirm certain determinations of a mineral, indeed the trait is not influenced by impurities. It is obtained by rubbing the mineral on the frosted surface of unglazed porcelain;

  • Since the decree of January 2002 using the term « semi-precious » to describe a stone in commerce is prohibited in France, this is the reason why on this website, the stones of this old classification are named « fine ».

You can also provide your own stone (brought back from a trip, offered by a lover...) for me to set, for further information, see the section: set your stone.

And, if you want you can visit the crystals gallery, with nice pictures of gems and natural stones taken at the exhibition "order in chaos" at the natural history museum "La Specola" of Florence.
