The Gem Spectrum is Pala International’s free newsletter. Edited by Pala’s own Gabrièl Mattice, it is filled with interesting articles on various aspects of precious stones, including articles on Burma ruby and sapphire, tourmaline (including rubellite tourmaline), spinel, garnets such as demantoid, and a plethora of others.
We distribute The Gem Spectrum free within the United States to select members of the gem and jewelry trades.
