“We trust only the gems we mine ourselves,”
says Valerio Zancanella, owner of TUMICO
“We mine our gems in Africa in the Tunduru area in Tanzania, which is famous for a beautiful 54-carat flawless pink diamond,” says the owner of TUMICO. Polished to perfection, it was presented as a wedding gift to the British Queen Elizabeth in 1947. They say she wears it even today.
Raw stones are polished by the best gemcutters in Italy, where they obtain their final form. Investment gems are certified by world-renowned gemmological laboratories in Austria and Switzerland.
