Daniel, Fossicking is the Australian term for rock-hounding…i.e.
collecting. As for Botswana Agate, I would call your attention to the
awesome peach colored carnelians that frequently occur there and are
sometimes available at designer cabochon venues. As far as I know,
they are available from nowhere else! Another interesting aspect of
the Botswana agate deposit is the existence of a massive white based
tree agate which is EXACTLY like the agate of the same name which has
been extracted from the Deccan traps of India. Indeed, I would
imagine that some of this material has been marketed as Indian while
coming from Botswana. Most of the product from Botswana has been
marketed in the past by Topstones of Capetown, South Africa. As you
well know, when natural gem products enter into the devious channels
of commerce the matter of provenance becomes inconsequential. ( "Thai
"Sapphire from Sri Lanka,“Burma” Ruby from Kenya, “Australian” Opal
from Brazil, “New Zealand” Jade from British Columbia, etc. etc.)
Happy fossicking! Ron at Mills Gem, Los Osos, CA.
