CATHEDRALS, AMETHYST AND CITRINE

These true wonders of nature all come from a series of basaltic flows in the southern Brazilian state of Rio Grande do Sul. They are mined by hard rock mining methods, then cleaned cut and polished by local craftsmen.

Cathedrals are graded for sale by exterior size and shape; crystal size, color and perfection; and overall appearance. Also, the appearance of other minerals such as calcite and quartz which form after the amethyst, may add to the value.
