Real vs. Fake Gemstones: 6 Easy Ways to Spot the Original

Beauty is frequently deceiving in the colourful world of precious and semi-precious stones. Buyers now find it more difficult to tell real gemstones from fakes due to developments in imitation and synthetic manufacturing techniques. Finding genuine gemstones is crucial whether you're an investor, a gemstone collector, or someone looking for astrological benefits.

With the help of this thorough gemstone test guide, you can make confident and well-informed purchases by learning six infallible techniques to distinguish genuine gemstones from fakes. Even if you're not a gemmologist, these gemstone authentication strategies will help you uncover the mysteries of real stones.

Importance of Knowing Real vs Fake Gemstones

Imitations abound in the gemstone market: glass, plastic, dyed quartz, synthetic stones, and processed materials that appear strikingly natural but are not genuine or valuable. Purchasing imitation gemstones might cost you not just money but also the spiritual advantages that come with real stones.

Understanding how to distinguish genuine jewels from imitations:

• Safeguards your monetary investment.

• Guarantees the astrological or spiritual efficacy of the stone.

• Assists you in making informed purchases from trustworthy sources.

Let's discover the best gemstone authentication advice that every purchaser needs to be aware of.

6 Ways to Check Real vs Fake Gemstones

Visual Inspection: Clarity, Colour, and Inclusions

Using your eyes to recognise genuine gemstones is the first step. Rarely are natural gemstones flawless. Unlike synthetic or imitation stones, they frequently include minute inclusions, colour zoning, or inherent flaws.

What to Look for

• Inclusions: Tiny internal defects or inclusions are common in natural stones. Fake ones typically have air bubbles or are perfect, especially if they are made of glass.

• Colour: Although genuine gemstones can have vivid hues, they frequently show minor variances. The colour of fake stones is typically consistent and overly flawless.

• Shine: Genuine gemstones have a distinct depth of gleam. For example, genuine emeralds have a soft, almost smooth sheen, whereas imitations may seem excessively shiny or glassy.

The Weight Test: Density

Real gemstones weigh a certain amount because of their unique densities. Typically, fake stones composed of glass, resin, or plastic are lighter.

How to Test

• Place the gemstone in your hand or contrast it with another genuine stone that is the same size and form.

• Because of their greater density, real gemstones frequently feel heavier.

Real-World Example

Compared to a glass or synthetic sapphire of the same size, a real sapphire will weigh significantly more. It's most likely phoney if it feels excessively light.

When purchasing loose stones or beads in large quantities, this gemstone test guide tip is really beneficial.

Scratch Test: Hardness of The Stone

According to the Mohs scale, each gemstone has a unique hardness. For instance, quartz is ranked about seven, diamonds at ten, and sapphires and rubies at nine. To determine the legitimacy of the stone, you can carefully conduct a basic scratch test at home.

Method

• Use a lower-hardness object, such as a copper coin, to try lightly scratching the stone.

• Softer imitations could have scratches, but genuine gemstones won't.

Be careful of

• Unless you are testing inexpensive or suspected fakes, don't scratch pricey jewels directly. This is a last resort test that is best left to experts.

• One of the oldest methods for authenticating gemstones that has been used for millennia is this one.

The Fog Test: Heat and Breath

The fog test is among the simplest do-it-yourself methods for testing gemstones. While artificial stones hold heat longer, real stones release it more rapidly.

Method

• Breathe on the stone while holding it, simulating fogging a mirror.

• A genuine gemstone will become clear in 1-2 seconds.

• Glass in particular will remain hazy for at least five seconds.

Without any instruments, this is a very fast method for telling real gemstones from fakes in a market or store.

UV Light Test: Glow of the Stone

Many gemstones can reveal their secret nature when exposed to ultraviolet (UV) light. Under UV light, some real stones glow differently than imitations.

Examples

• When exposed to UV light, real diamonds usually glow blue.

• Fake diamonds frequently exhibit a different colour or no fluorescence.

• Red or pink fluorescence can be seen in sapphires and rubies.

• Typically, emeralds don't fluoresce; if they do, it may be artificial.

What You Need

• This test can be aided by a basic UV torch or blacklight that can be purchased online.

• Gem labs frequently employ this gemstone test guide technique, which is simply adaptable for initial inspections at home.

Gemmological Report for Clarity

Nothing compares to a certified lab result, regardless of how many tactics you try. Always request a certificate from an accredited gemological lab before buying a gemstone that costs more than a few thousand rupees or dollars.

What to Look for in a Certificate

• Type and variation of stone (e.g., untreated emerald, natural ruby).

• Origin (if any).

• treatments (such as oil-filled or heat-treated).

• GIA, IGI, GRS, IGS, or a national gem testing lab are examples of certification bodies.

High-quality synthetic or treated stones might evade even the greatest gemstone authentication advice, so a certificate is your best bet.

Common Fake Gemstone Types to Look

Some of the common fake gemstones types to watch out for and keep a look at while looking and understanding gemstone authentication tips:

Glass or Resin Immitations

These are the most popular imitation gemstones; they are made to resemble actual stones using coloured glass or artificial resin. They frequently lack natural inclusions and seem overly glossy or perfect. They can be easily identified with a straightforward visual or scratch test since they are lighter and more prone to scratches.

Synthetic Gemstones

Synthetic gemstones are created in labs and are identical to real ones in terms of their chemical makeup. They may even pass some physical tests and have a virtually comparable appearance to real stones. They do not, however, have natural flaws and geological background that can be determined by professional examination or certification.

Dyed Stones

Often, inexpensive stones like agate or quartz are dyed to look like vivid sapphires, emeralds, or rubies. Over time, the colour may bleed or fade, especially when exposed to heat or water, and it may seem overly intense or homogeneous. The dye may be visible with close examination or soaking in warm water.

Doublets and Triplets

A small slice of genuine gemstone is fused with glass or another substance underneath to create these layered stones. They are frequently used to mimic the true look of opals and emeralds while lowering costs. If you look closely from the side, you can see the glue lines or layers.

Preventive Buying Measures

Here are some more guidelines to protect your investment in addition to the gemstone test guide mentioned above:

Purchase from reputable sellers at all times

Select gemstone sellers or jewellers who have a good track record, validated ratings, and clear return policies. Reputable vendors, both online and off, will provide certification and be happy to answer your enquiries.

Examine costs

The price is most likely fraudulent if it looks too wonderful to be true. The value of real gemstones is determined by the market. Stones that are heavily discounted or appear suspiciously inexpensive should be handled carefully.

Verify the setting quality of the jewellery

Seldom are genuine gemstones put on subpar metal. A warning sign is if you're purchasing a "ruby ring" set in brass or a subpar alloy.

Why is it important to know the difference between real and fake gemstones?

Knowing how to identify real gemstones helps protect your investment, ensures the stone’s astrological effectiveness, and prevents losses from fake or synthetic imitations.

What are the common signs of fake gemstones?

Fake gemstones often appear too perfect, with no inclusions, overly consistent color, glassy shine, and lighter weight compared to genuine natural stones.

How can I test if my gemstone is real at home?

Simple tests include visual inspection for inclusions, the fog test, the weight test, the scratch test, and checking under UV light. However, professional certification is always recommended.
