无意影响楼主的心情 只想进行科普 关于帕拉伊巴碧玺的权威论述 请参考ICA网站信息 http://www.gemstone.org/index.php?option=com_content&view=article&id=113:sapphire&catid=1:gem-by-gem&Itemid=14 Paraiba tourmalines are almost always quite small, since the beautiful cupriferous tourmaline crystals from the 'noble hill' in Paraiba were almost all fragments when they were discovered. Larger raw stones with a weight of over 5 grammes which had not cracked were rare, and only very few crystals had a weight exceeding 20 grammes. For that reason you are very unlikely to find a large Paraiba tourmaline at a jeweller's or gemstone merchant's - quite apart from the fact that few specialist merchants actually offer this highly esteemed gemstone rarity at all.
