# Apatite Guide: Colours, Hardness & How to Spot Genuine Stones **By Cristian Maxim** ยท 2026-07-03 Quick answer Apatite is a soft phosphate mineral best known for its **electric neon blue-green colour**. It is the stone that **defines 5 on the Mohs scale**, so it scratches and chips more easily than quartz and needs gentle care. Its name comes from the Greek for **"to deceive"**, because it is so often mistaken for other gems like tourmaline, beryl and topaz. Most apatite is genuine and affordable; the main thing is to handle it carefully and keep it away from heat and acids.

Care and water](#apatite-care) - [How to choose apatite](#choose) - [Frequently asked questions](#faq) Apatite is one of the most vivid stones you can own, and one of the most confusing. Its best pieces glow an electric blue-green, yet it is soft enough to define a step on the hardness scale, and its very name is a warning that it is easily mistaken for other gems. This guide explains what apatite really is, where the name comes from, its colours and varieties, how to tell it from its many lookalikes, and how to care for a stone that needs a gentle hand. ## What is apatite? Apatite at a glance Family: Phosphate, Ca5(PO4)3(F,Cl,OH) Defines: 5 on the Mohs scale Colour: Blue, green, yellow, violet Hardness: 5 (soft, brittle) Name: Greek for "to deceive" Care: Keep from heat and acids crystalshealing.co.uk Apatite is not a single mineral but a small family of **calcium phosphate** minerals, with the formula Ca5(PO4)3(F,Cl,OH). The most common gem type is fluorapatite. It is the same material your tooth enamel and bones are largely made of, and the rock that the world's phosphate fertilisers come from, so while it may be new to many crystal collectors, it is one of the most important minerals on Earth. For gemstones, the headline fact is hardness. Apatite sits at exactly **5 on the Mohs scale**, and in fact it is the reference mineral that defines that point on the scale. That makes it noticeably softer than quartz (7) and much softer than topaz or beryl, so it scratches, chips and cleaves more easily and needs careful handling. Its colours come from trace elements, and the most sought-after pieces are an intense, almost glowing blue-green often compared to Paraiba tourmaline. ## Why is it called "the deceiver"? The name apatite comes from the Greek word meaning "to deceive." It was given because the mineral appears in so many colours, and so closely resembles other gems, that miners and cutters kept mistaking it for something else: blue apatite for tourmaline or aquamarine, green and yellow apatite for peridot or beryl, violet apatite for amethyst. Even today apatite is one of the most misidentified stones in the trade. The good news is that this works in your favour as a buyer: apatite gives you gem-quality colour at a fraction of the price of the stones it imitates, as long as you know what you are looking at. ## Colours and varieties Apatite colours Neon Blue Green Yellow Violet Trace elements create the colour; neon blue-green is most prized crystalshealing.co.uk Apatite occurs in a wide spread of colours, which is part of why it was so often mistaken for other gems: - **Neon blue-green**, the most famous and most valued, with vivid examples coming from Madagascar. - **Blue**, from soft sky tones to deep, saturated blue. - **Green**, including the yellow-green "asparagus stone." - **Yellow to golden**, warm and bright. - **Violet to purple**, and more rarely pink and colourless. Some apatite also shows a cat's-eye effect (chatoyancy) when cut as a cabochon, a moving line of light across the surface.

It tends to show more wear, tiny chips and scratches over time, which a harder gem would not. - **That neon glow.** The electric, slightly "wet-looking" blue-green of fine apatite is distinctive; a price far below Paraiba tourmaline for that look usually means apatite, which is fine if it is sold as such. - **Watch for glass and heavy treatment.** Suspiciously cheap, perfectly clean "neon" stones with bubbles can be glass; some apatite is gently heated to improve colour, which is normal when disclosed. - **Buy from an honest seller** who names the stone and any treatment.

Care and water Apatite needs more care than most crystals, because at Mohs 5 it is soft and somewhat brittle, and it is sensitive to heat and acids. It can scratch against everyday objects, chip if knocked, and lose polish if treated roughly, so it is one to protect rather than throw in a pocket. You can compare it with tougher stones in our guide to the [most durable gemstones for everyday wear](/blogs/crystals-tips/the-most-durable-gemstones-for-everyday-wear). To care for apatite: keep it away from heat, steam and sudden temperature changes; never use ultrasonic cleaners; avoid acids, household chemicals, perfume and hairspray; and clean it with a soft, slightly damp cloth rather than a long soak. A brief rinse in cool water is fine, but do not leave it sitting in water. Store it on its own, away from harder stones that could scratch it, and choose pendants, earrings or protected ring settings for daily wear. See our [water-safe crystals guide](/blogs/crystals-tips/water-safe-crystals-what-can-go-in-water-and-what-to-avoid) and [how to store crystals](/blogs/crystals-tips/how-to-store-crystals). ## How to choose apatite Apatite is chosen mainly on colour, since fine examples rival far pricier gems. Look for: - **Colour you love**, with vivid neon blue-green at the top of the range. - **Good clarity or an even cabochon**, depending on whether the piece is faceted or polished. - **Honest disclosure** of the stone and any heat treatment. - **A practical setting**, given the stone is soft; pendants and earrings suit it best. - **Sensible expectations on wear**, treating apatite as a special-occasion or carefully-worn piece rather than a knockabout everyday stone.

Its name comes from the Greek for "to deceive," because it comes in so many colours and is so often mistaken for other gems such as tourmaline, beryl and peridot. How hard is apatite? Exactly 5 on the Mohs scale, the mineral that defines that point. That makes it soft for jewellery, so it needs careful handling. Can apatite go in water? A quick rinse in cool water is fine, but do not soak it, and keep it away from heat and acids, which can damage the surface. Is apatite the same as Paraiba tourmaline? No. They can look alike in neon blue-green, but apatite is a softer, more affordable phosphate mineral, while Paraiba is a rare, much harder and pricier tourmaline. Is apatite expensive? Usually no. It offers gem-quality colour at a fraction of the price of the stones it resembles, which is a big part of its appeal. ### Related reading - [Aquamarine: another blue stone apatite is mistaken for](/blogs/crystals-tips/aquamarine-what-it-is-how-to-spot-it-and-how-to-care-for-it) - [Fluorite: another soft, colourful mineral](/blogs/crystals-tips/fluorite-the-most-colourful-mineral-blue-john-and-how-to-care-for-it) - [Are my crystals real? 7 simple checks](/blogs/crystals-tips/are-my-crystals-real-7-simple-checks-to-spot-fakes) - [Water-safe crystals guide](/blogs/crystals-tips/water-safe-crystals-what-can-go-in-water-and-what-to-avoid) - [How to store crystals](/blogs/crystals-tips/how-to-store-crystals) --- > Source: [Crystals Healing UK](https://crystalshealing.co.uk/blogs/crystals-tips/apatite-guide-colours-hardness-and-care-uk)
