African turquoise is actually a form of jasper, not true turquoise, scientifically classified as a cryptocrystalline variety of quartz that displays beautiful blue-green coloration with distinctive dark veining and matrix patterns. This metamorphic stone is found primarily in Africa and gets its name from its turquoise-like appearance, though it lacks the copper and aluminum phosphate composition of genuine turquoise. African turquoise is prized for its striking color combinations, durability, and unique patterns that make each piece naturally distinctive, offering jewelry designers an affordable alternative to traditional turquoise with its own unique character and beauty.
- Color range: Blue-green base with brown, black, or gray veining; varies from pale mint to deeper teal with natural matrix patterns throughout
- Sizes: Available from small beads (4-6mm) to large cabochons and carved pieces (several inches); consistent availability in various sizes
- Shapes: Excellent for cabochons, beads, and carved elements; the natural patterns work beautifully in both smooth and textured finishes
- Origin: Primarily mined in Africa, particularly in regions of South Africa and other African countries with suitable geological formations
- Hardness: 6.5 to 7 on Mohs scale, good durability for most jewelry applications though softer than genuine turquoise's typical hardness
- Patterns: Distinctive veining and matrix patterns in contrasting colors; each piece shows unique natural designs created during formation
