Turquoise

Carat weight is important for larger, high-quality cabochons and freeforms with desirable color and minimal matrix. Because turquoise is often used in sizeable pieces for bracelets, necklaces and belt buckles, larger cohesive pieces of fine quality can command higher absolute values, though price per carat is also strongly tied to color and origin.

Color is the primary value factor. The most coveted turquoise shows a uniform, medium robin's-egg blue (sometimes called 'Persian blue') with minimal green or gray. Strong greenish or very pale hues trade at lower values, though some markets prefer fine spiderweb matrix patterns that add character.

For turquoise, clarity refers to density, porosity and matrix distribution. Compact, low-porosity material that can take a good polish is preferred. Stones with excessive porosity, chalky texture or unstable matrix are less durable and typically require stabilization to be usable in jewelry.

Turquoise is usually cut as cabochons, beads and inlay pieces. Quality cutting emphasizes shape symmetry, balanced matrix distribution, and a smooth, even polish. Because of its relative softness, turquoise is best used in settings that protect edges and surfaces from abrasion.

Important turquoise sources include Iran, the southwestern United States (Arizona, Nevada, New Mexico), China, Egypt and others. Many historic mines have reduced output or closed, while newer operations and reactivated mines in China and the U.S. supply much of today's material. Natural, untreated high-grade turquoise is relatively scarce.

Demand is strong and culturally rooted, especially in Native American and Southwestern jewelry traditions, Middle Eastern adornment and global fashion. Turquoise remains popular in both artisanal silver work and contemporary designer pieces.
