Qu'est-ce qu'une pierre fine ?
Les pierres fines sont des gemmes qui ne font pas partie des quatre pierres précieuses. Attention, seules les pierres issues de gisements de minéraux naturels peuvent être dénommées comme des pierres fines, elles ne sont donc en aucun cas reconstituées ou synthétiques. Autrefois appelées également "pierres semi-précieuses", ce terme est désormais interdit dans le commerce, car source de confusion pour les consommateurs.
À ce jour, le nombre de pierres fines varie selon les classifications, mais les plus répandues sont l’améthyste, la topaze, la citrine, l’aigue-marine et la tourmaline verte . On compte aussi l'aventurine, l'onyx, ou encore le quartz.

Elles se déclinent dans toutes les couleurs, tailles et formes et certaines peuvent même être plus rares et donc par conséquent plus onéreuses que des pierres précieuses.
