890++Turquoise is one of the oldest and most admired gemstones in the world, treasured for its beautiful blue and green shades. From ancient Egyptian jewelry to Native American craftsmanship and modern fashion accessories, turquoise has remained a timeless favorite. However, because of its popularity and limited natural supply, the market is flooded with imitation, dyed, and treated stones.

If you're planning to buy turquoise for jewelry, collection, or astrological purposes, it's important to know how to distinguish a genuine turquoise stone from a fake one. This guide explains the key characteristics of natural turquoise, common imitations, and practical tips for making a confident purchase.

What Is Turquoise?

Turquoise is an opaque gemstone composed of hydrated copper and aluminum phosphate. Its distinctive color is primarily influenced by:

• Copper – Produces blue shades.
• Iron – Creates greenish tones.

Natural turquoise is found in countries such as:

• Iran
• United States
• China
• Mexico
• Egypt

Among these, Persian (Iranian) Turquoise is especially renowned for its vibrant sky-blue color and high quality.

Why Fake Turquoise Is So Common

Natural high-quality turquoise is relatively rare. To meet market demand, manufacturers often produce imitation stones using materials such as:

• Dyed howlite
• Dyed magnesite
• Plastic
• Resin
• Glass
• Composite turquoise

Some treated stones look very convincing, making it difficult for buyers to identify genuine turquoise without proper knowledge.

Characteristics of Genuine Turquoise

1. Examine the Color

Natural turquoise typically displays:

• Sky blue
• Robin's egg blue
• Blue-green
• Greenish-blue

The color should appear natural rather than overly bright or artificial.

Be cautious if the stone has:

• Neon blue color
• Extremely uniform coloring
• Paint-like appearance

Many imitation stones are dyed to achieve unnaturally vivid shades.

2. Look for Natural Matrix Patterns

One of turquoise's most distinctive features is its matrix—the network of veins or patterns created by the host rock.

Natural matrix may appear as:

• Brown webbing
• Black veins
• Golden patterns
• Spiderweb designs

Each natural turquoise stone has a unique matrix pattern.

Fake turquoise often has:

• Repeated printed patterns
• Perfectly symmetrical webbing
• Artificial-looking lines

Keep in mind that some genuine turquoise is naturally free of matrix.

3. Check the Surface Texture

Natural turquoise usually has:

• A smooth polish
• Slight natural irregularities
• A waxy to slightly matte luster

Plastic imitations may feel:

• Too glossy
• Lightweight
• Artificially smooth

4. Inspect Under Magnification

Using a jeweler's loupe, look for:

Genuine Turquoise

• Natural grain
• Minor inclusions
• Organic matrix structure

Fake Turquoise

• Air bubbles (common in glass)
• Dye concentrations
• Printed or painted patterns

Air bubbles are a strong indicator that the stone is glass rather than natural turquoise.

5. Evaluate the Weight

Turquoise is relatively dense.

Plastic or resin imitations often feel noticeably lighter than natural turquoise of the same size.

Although weight alone cannot confirm authenticity, it can provide a useful clue.

6. Observe the Temperature

Natural gemstones generally feel cool to the touch when first handled.

Plastic imitations usually warm up quickly and may feel less substantial.

This simple observation can sometimes help distinguish natural stone from plastic.

Common Turquoise Treatments

Not all treatments mean a stone is fake. Many genuine turquoise stones undergo enhancements to improve durability.

Stabilized Turquoise

A resin is infused into porous turquoise to strengthen it.

This is a common and widely accepted treatment, provided it is disclosed by the seller.

Dyed Turquoise

Some lower-quality turquoise is dyed to improve its color.

Dyed stones are genuine turquoise but have been artificially enhanced.

Reconstituted Turquoise

Small turquoise fragments are mixed with resin and compressed into larger pieces.

Although it contains turquoise material, it is not considered natural solid turquoise.

Common Fake Turquoise Materials

Dyed Howlite

One of the most common substitutes.

Characteristics:

• Bright blue dye
• Gray or black veining
• Lower value than natural turquoise

Dyed Magnesite

Another frequently used imitation.

It resembles turquoise after dyeing but has different mineral properties.

Plastic

Plastic replicas are generally:

• Very lightweight
• Warm to the touch
• Overly glossy

Glass

Glass imitations often contain:

• Air bubbles
• Extremely smooth surfaces
• Bright artificial color

Professional Identification

The most reliable way to identify genuine turquoise is through professional gemological testing.

Laboratories use specialized equipment to determine:

• Natural or imitation origin
• Treatments
• Mineral composition
• Quality characteristics

A gemstone certificate provides valuable information and peace of mind.

Tips for Buying Genuine Turquoise

Buy from Reputable Dealers

Choose trusted gemstone sellers with transparent policies and positive customer reviews.

Ask About Treatments

Request full disclosure regarding:

• Stabilization
• Dyeing
• Resin filling

Request Certification

For valuable purchases, always ask for a certificate from a recognized gemological laboratory.

Compare Prices

Natural, untreated turquoise is relatively rare.

If the price seems unusually low, investigate carefully before purchasing.

Caring for Genuine Turquoise

Turquoise is softer and more porous than many gemstones.

To keep it looking its best:

• Avoid harsh chemicals.
• Remove jewelry before swimming.
• Keep away from perfumes and lotions.
• Clean gently with a soft, damp cloth.
• Store separately from harder gemstones to prevent scratches.
