- Greenish Blue: This hue can still be valued significantly, depending on its richness and saturation.*
- Green: Generally, when turquoise appears distinctly green, it may denote lower quality, but it can still appeal to collectors who appreciate diversity.*
Keep in mind that color uniformity enhances desirability. A stone with a consistent hue throughout is generally preferred over one with significant variation.
Clarity and Matrix Effects
Clarity in turquoise refers to how transparent or opaque the gem appears. High-quality turquoise is usually more opaque, leading to a striking look. However, clarity can be affected by matrix patterns. The matrix is the host rock structure within turquoise and adds complexity to its appearance.
