Brazilian artisan Guena says, 'In 1980, I left a career as an accountant. I began as an artisan's assistant and a sculptor, and became fascinated with gems and crystals. Today I travel throughout Brazil in search of crystals from Bahia, emeralds from Minas Gerais, and agates from Rio Grande do Sul. I realize I have experienced a great personal transformation. I have more patience for art than for logic!'
