To identify a real natural zircon stone, check five things: its sparkle, its colour, its weight, the tiny marks inside it and its certificate. Real zircon throws rainbow-like flashes, feels heavy for its size and usually has small natural inclusions. A gemstone certificate or a gem expert gives the final answer.
This buying guide explains each check, how natural zircon differs from artificial stones like cubic zirconia, and how to buy and care for it. You can see real stones in our natural zircon collection.
What is natural zircon?

One of the oldest minerals on Earth. Natural zircon forms deep in the earth over millions of years. Some pieces are over 4 billion years old.
Many colours. Zircon comes in blue, yellow, green, white, pink and brown. Blue is the most popular colour for jewellery.
Where it is found. Important sources include Sri Lanka, Cambodia and Australia.
December's birthstone. Zircon is a birthstone for December, so it makes a special gift for anyone born that month. Its sparkle makes it a favourite in rings, necklaces and earrings.
Natural zircon vs artificial stones
Artificial stones are made in a lab. Also called synthetic stones, they look like natural gems but are not found in nature. Common examples are cubic zirconia and lab-grown diamonds.
| Feature | Natural zircon | Artificial stones |
|---|---|---|
| Formation | Formed in the earth over millions of years | Made in factories in days or weeks |
| Value | More valuable, because it is rare | Less expensive and easier to make |
| Durability | Hard, but can chip if knocked | Often tougher, as they are designed to resist damage |
| Appearance | Unique sparkle and natural-looking colour | Can look perfect, sometimes too shiny or fake |
| Origin | Sri Lanka, Cambodia, Australia and other sources | Laboratories worldwide |
Zircon is not cubic zirconia
A common mix-up. The names sound alike, but zircon is a natural gemstone, while cubic zirconia is an artificial stone made in a lab. If a seller uses the two names loosely, ask exactly which one you are buying.
How to identify a real natural zircon stone

1. Check the sparkle
Look for rainbow flashes. Real zircon bends light in a special way, so it shows a rainbow-like effect as you move it under light. Fake stones may shine too brightly, look too perfect or look dull.
2. Look at the colour
Rich, natural tones. Natural zircon has rich, deep colours. If the colour looks too bright or unreal, the stone may not be genuine.
3. Feel the weight
Heavier than most fakes. Natural zircon is heavier than many artificial stones. Hold it in your hand and feel its weight.
4. Check for inclusions
Tiny marks are a good sign. Real zircon often has tiny marks or lines inside, called inclusions. Lab-made stones can look too perfect.
5. Test the hardness
A simple scratch test. Zircon is harder than glass, so it can scratch glass. It can still chip if hit hard, so test gently.
6. Ask for a certificate
Proof on paper. Always ask the seller for a gemstone certificate. It confirms that the zircon is real and natural.
7. Get a professional opinion
See an expert. A jeweller or gemmologist can examine the stone under a microscope and tell you for sure.
Why it matters whether your zircon is real
- Value: natural zircon is rare and worth more than artificial stones.
- Beauty: real zircon has a sparkle that fakes cannot quite match, and no two stones are exactly alike.
- Fair price: knowing what you have means you pay the right price for it.
Buying tips for natural zircon
- Buy from a trusted seller: choose a jewellery store or gemstone dealer with good reviews. Avoid unknown or unverified sellers.
- Understand the price: real zircon costs more than fake stones. If the price seems too good to be true, the stone may be fake.
- Ask questions: ask about the stone's origin, colour and quality. A good seller will happily answer.
- Check the setting: real zircon is usually set in good-quality gold or silver. A cheap-looking setting can be a warning sign.
- Know the colours: blue is the most popular, but yellow and green are beautiful too, and each colour has its own charm and value.
Natural or artificial: which should you choose?
Choose natural zircon if you want a unique gem with real history. Its natural imperfections make each piece special.
Choose an artificial stone if you want pretty jewellery on a smaller budget. Just make sure it is sold to you as artificial, at an artificial price. Browse more genuine gemstones or our varieties of gemstones.
How to care for your zircon
- Clean gently: use warm, soapy water and a soft brush or cloth. Avoid harsh chemicals.
- Store it safely: keep your zircon jewellery in a soft pouch, away from other hard stones, to avoid scratches.
- Handle with care: take it off for heavy work, as zircon can chip.
- Avoid heat: high heat and sudden temperature changes can damage zircon's colour and shine.
