A unique and vibrant blue, the gemstone comes from Sleeping Beauty Mountain in Arizona where Daniel Smith found a deposit that lives up to high expectations. It is lightfast and permanent, with none of the transient color fade that plagues most turquiose. Turquoise has a unique porous nature that produces granular washes. Juicy washes flow from the brush and drybrush work has the intense texture found only in a mineral pigment. Traditional mineral pigments often have a muted feel and our unique Turquoise Genuine has a true brilliance. Daniel Smith uses the highest grade mineral that is found closest to the earth's surface, where environmental factors have enhanced the structure to gemstone quality and deepened the tonal richness to a remarkable blue. Historic references of Turquoise date back as far as Egypt's first dynasty. Turquoise from the American Southwest has been unearthed in Aztec ruins and Persian turquoise was used as trading currency.
