Platinum
Platinum exists in higher abundances on the Moon and in meteorites. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example.
Ricardo Basta
Basta has also become recognized in his field as a platinum expert. In the mid-80s, when information was scarce on the subject, he began to cast in platinum. Most design houses weren’t using platinum quite yet. Through the process of trial and error, he developed an understanding of the best way to work with the precious metal. Since then, the learning curve has decreased due to the popularity of the metal and the development of resources, equipment and technology. Also, due to his experience with platinum, he has written contributing articles for the Platinum Guild International on the subjects of casting and antique jewelry restoration.
