Paraiba tourmalines are among the most sought after colored stones in the world. Prices of top stone
Paraiba tourmalines are among the most sought after colored stones in the world. Prices of top stones have perhaps appreciated more than any other gemstone over the last 10-15 years. These stones are from the Mavuco area of Mozambique. Only some 10% of recovered stones actually show blue-to-green Paraiba-like colors without heat treatment. Unfortunately, there is little new production and stones like these are nearly impossible to find. -- source link
