Sacco began expressing an interest in minerals in the early nineteen sixties.
Now, almost forty years later, his mineral collection is one of the finest in
private hands in the world. Meticulously assembled over a period of four
decades, it contains over 3000 stunning specimens. Examples from southern
African countries such as Namibia, South Africa, Mozambique, Democratic
Republic of the Congo and Zimbabwe form the core of the collection. One of the
localities in Namibia, the Tsumeb mine, contributes almost two-thirds of the
minerals illustrated in this book. Tsumeb is regarded as the premier site of
fine mineral specimens and the ones to be seen in the Sacco collection are
outstanding, and many are acknowledged to be the best in any collection.The
visual aesthetics of the minerals are breathtaking, but the collection has
intrinsic scientific value as well because many of the mines that produce
these fabulous minerals are now closed. They are therefore no longer
obtainable from the source. This assemblage of mineralogical treasures can be
considered of national importance as it preserves a national heritage that
would have otherwise have been lost forever.

Cairncross is professor of geology at the Rand Afrikaans University. He is the
co-author of two books ‘The Minerals of South Africa’ and ‘The Manganese
Adventure’. He has also published extensively on southern African minerals
and he is an accomplished photographer of fine minerals and gemstones. His
photographs have been featured in a variety of publications and he regularly
presents lectures on mineralogical topics. Professor Cairncross has an
inherent interest in South Africa’s geological and mineralogical heritage
and much of his research efforts are aimed at documenting and photographing
important geological sites in southern Africa and promoting the preservation
on South Africa’s mineralogical heritage. This is the third high-quality
book to be written by Professor Cairncross and it is fitting that it should
feature the Desmond Sacco collection, the finest private collection of
southern African specimens in the world.
