NOTE: The
price values listed on this page are "top dollar" estimates.
Cabochon prices vary depending on country and the world market.
We price our agates at approximately 'one quarter' of the
listed gemstone value. Our special handpicked lots come direct
to us from our miner amigos who have worked with us on a
semi-exclusive basis for the past 5 years. Their talent and
ability to bring the
most out of every stone they touch gives them the distinction
of being the top polishers in the town of Calvillo.
