How to Identify Genuine Neyshabur Turquoise
With the growth of synthetic and treated stones worldwide, accurate identification has become essential. Below are key professional guidelines:
1. Authentic Color Characteristics
Real Neyshabur turquoise shows slight natural variations across the surface:
- Sky blue
- Blue-green hues
- Natural matrix patterns
Artificial stones often display a completely uniform color with a plastic-like appearance.
2. Mineral Surface Texture
Natural turquoise has a slightly porous mineral texture.
Fake versions often:
- Feel overly smooth
- Look like plastic or glazed ceramic
- Have an unnatural shine
3. Hardness and Density
Authentic Neyshabur turquoise is relatively hard.
If the stone scratches easily, it is likely:
- Dyed howlite
- Dyed magnesite
- Resin composite
High-quality turquoise is also heavier than resin or plastic imitations.
4. Heat and Dye Reaction
When exposed to heat (only for unmounted stones), fake turquoise may show:
- Dye leakage
- Odor from resins or plastics
Natural turquoise does not release odors or melt.
5. Professional Certification
For high-value stones, verification by a certified gemologist or reputable laboratory is recommended. Certificates often include:
- Origin
- Treatment type
- Color grade
- Cluster/matrix description
Common Types of Fake or Treated Turquoise in the Market
The most frequently encountered alternatives include:
- Dyed howlite and magnesite (most common imitation)
- Stabilized turquoise with heavy resin absorption
- Compressed/reconstituted turquoise made from powder
- Fully synthetic turquoise created from plastics or dyes
Understanding these helps buyers avoid confusion and ensures transparent pricing.
