Pacheco and his wife, Marilyn, carefully craft each of their necklaces from Kingman turquoise. It takes about a week to make one necklace. Each bead must be carefully shaped, tapered, and strung. They are separated by tiny shell Heishi so that each turquoise wafer stands out. These necklaces are unique and will be a source of enjoyment for many years. Most artists do not make the wafer Heishi anymore because of the difficulty and breakage rate.
