Ready for a rare gem whose name rolls right off the tongue? Meet phosphosiderite.

Pronounced faws-fawsi-der-ayte, phosphosiderite is a funky-looking crystal (with an equally funky-sounding name) that’s probably flown under your radar as you ventured into the world of gemstones. However, this obscure crystal deserves a spot on your list.

What is phosphosiderite stone? It’s a (typically) purple to purplish-red mineral made of phosphate and iron.

An interesting thing about phosphosiderites is that they share the same composition, but they tend to have varying characteristics and occur in all kinds of eye-catching colors. 

In addition to its unique appearance, phosphosiderite stone is known to possess vibrant energies that aid in your wellness — especially in spiritual growth.

About Phosphosiderite Stone

Phosphosiderite was only discovered in the late 19th century, making it a relative newcomer to the world of gemstones. 

The name phosphosiderite relates to the stone’s mineral makeup. It derives from Latin phospho (for “phosphate”) and sídēros (for “iron”). 

It’s also known as piedra voga, meaning “pink stone,” and la rosa voca, meaning “pink rock.” Phosphosiderite was once called “metastrengite,” but this pseudonym is mostly obsolete.

Some crystals can be used as zodiac stones to balance certain astrological signs. The zodiac phosphosiderite is attuned to Pisces. 

So how can you tell if phosphosiderite is real? Closely observing its mineral traits will tell you everything you need to know!

Phosphosiderite Specifications & Characteristics

Phosphosiderite is a dimorph of strengite, a fairly rare iron phosphate mineral.

Some argue that from a technical standpoint, phosphosiderite isn’t truly a gemstone — it’s moreso just a mineral. 

Crystals occur in an array of colors ranging from opaque to transparent. The most common being purple, such as orchid-purple or lavender, often with hues of red or pink mixed in, as well.

Occasionally, phosphosiderite stones occur with yellow veining along their surface. The fine lines of yellow can vary showing darker or heavier lines and patches. As a result, there’s been some debate over whether phosphosiderite is a hydrated aluminum phosphate variety, like variscite. However, this has yet to be substantiated, so we’ll let you make of it what you will.

Phosphosiderite vs. Lepidolite

Phosphosiderite’s pretty purples are easy to confuse for other similarly-colored crystals, like lepidolite. They do share other similarities, as well. For instance, they both have monoclinic crystal structures and are relatively soft. 

However, in terms of phosphosiderite vs lepidolite, there are a few key differences that can help you distinguish the two minerals.

With regards to color, lepidolite is more similar to amethyst than phosphosiderite. It also exhibits fluorescence, whereas phosphosiderite does not. Lepidolite is also made of mica, while phosphosiderite is composed of iron and phosphorus. Another distinction is that phosphosiderite is slightly harder than lepidolite. 

Moving on, let’s explore some of phosphosiderite’s etymology. 

Phosphosiderite History

Phosphosiderite was originally discovered by a French mineralogist, Alfred Lewis Oliver Legrand Des Cloizeaux, in 1858. However, it was first classified as a "type I hurealite" upon discovery (which isn’t an accurate description). 

It wasn’t until 1890 that phosphosiderite earned its formal name — thanks to German authors Willy Bruhns and Karl Heinrich Emil Georg Busz. As mentioned earlier, they named phosphosiderite after its composition: phosphate and iron.

Ancient healers believed phosphosiderite could absorb negative energies, diluting them and releasing them to the world as positive energy. They also believed it could heal diseases, particularly chronic health problems.

Speaking of healing…

Phosphosiderite Healing Properties

Most gems can be used as healing stones to improve your physical, emotional, and spiritual wellness. 

Phosphosiderite is often referred to as a “jewel nugget of healing and hope.”  It’s believed to contain a lovely healing and calming vibration that helps the body at every level. Simply touching the stone's surface is thought to draw you to its tranquil energy and instantly boost your overall being. 

First, let’s see how phosphosiderite benefits your physical body.

Physical Healing

It’s been said that phosphosiderite has the propensity to cure any physical troubles, especially regarding skin and hair.

The mineral’s revitalizing energies may improve mental and motor function, especially when it pertains to the abdominal region. 

Struggle with insomnia? Phosphosiderite helps you shut down and relax so that you slip into a blissful slumber at bedtime.

Emotional Healing

Phosphosiderite is believed to plant seeds of hope when it is needed most. It produces calmness, comfort, and poise. It roots out excess worry and reinstates the steadiness.

Ever feel like you missed out on moments of happiness because you were too caught up with the stresses of life? Phosphosiderite can help you feel joy in every phase of life, even the difficult ones. 

Meditating with phosphosiderite can help you see the bigger picture. It stimulates greater visions for yourself and others, helping you see possibilities you never knew existed. 

Chakra Healing

Some minerals can help balance one or more of your chakras. Chakras are energy centers along the body that govern your mind, body, and soul in specific ways. 

You can use phosphosiderite as a chakra stone to balance all seven energy points. However, it especially attunes to the third eye chakra.  

Your third eye chakra is located on your forehead, between your eyebrows. It’s associated with intuition and foresight. Phosphosiderite uses its energy to awaken your third eye and enhance your awareness of the world around you and the celestial realm (or the realm of spirits). 

Spiritual Healing

Phosphosiderite is a crystal with an intense focus on the deeper aspects of life, revealing hidden lessons and opening your eyes to truths beyond what you can see with the physical eye.

Spiritually, it’s known to help you connect to other realms or planes of existence. It stimulates communications with higher levels of consciousness, helping you become more closely connected to humanity and everything that exists in the universe.

Shifting gears, what determines phosphosiderite’s worth? Let’s talk grading.

Phosphosiderite Gemstone Properties

Experts assess each gem’s physical characteristics to determine its worth. For phosphosiderite, they look at color, cut, clarity, and weight.

Color

Like many semi-precious gemstones, phosphosiderite doesn't occur in just one color. Its most common hue is purple. It tends to lean slightly red or pink, better describing it as violet or orchid purple. 

Rarer occurrences include dark purples, more akin to a deep plum, rose red, soft peachy pink, and reddish-brown. Sometimes, you can even find moss green or orange phosphosiderite.

Occasionally, colorless specimens also occur. In these, pleochroism is often present, causing flashes of pinks or reds depending on the angles at which you hold the stone. 

Cut

Collectors are particularly keen on phosphosiderite in its rough (or uncut) form. This is because rough specimens can be just as striking as faceted ones.

Rough phosphosiderite tends to be transparent or translucent. The specimens themselves tend to be relatively small, coming in below 2.5 cm in many cases.

Thanks to its spectacular colors, phosphosiderite is magnificent when faceted or cut into cabochons. Due to the mineral’s softness, it takes a skilled lapidary to do it correctly. 

Carvings, like phosphosiderite spheres, hearts, and other shapes, are also popular. 

Clarity

Some colorless specimens can display dazzling fire, making for stunning gem cuts.

Commonly, inclusions of cacoxenite produce spidery, yellow streaks, but they aren’t always visible in phosphosiderite cut for jewelry and seem to have little effect on price.

Carat Weight

Phosphosiderite that occurs in massive form is usually used to produce cabochons.

Colorless phosphosiderite tends to be extremely small.

Treatments

You won’t find fake phosphosiderite specimens often, but you may come across treated specimens. Sometimes, phosphosiderite is coated with paraffin or resins to enhance shine and stability. 

…But before phosphosiderite ever makes it to grading, it has to form!

Phosphosiderite Formation & Sources

Phosphosiderite forms in the oxidized zone of phosphorus-bearing ore deposits. It’s an alteration product of triphylite in granitic pegmatites, soils, and replacement minerals in bones and shells.

Phosphosiderite is often associated with other phosphate minerals, such as members of the apatite group, lithiophilite, strengite, and rockbridgeite.

Geographically, where does phosphosiderite occur?

Phosphosiderite Price & Value

Despite phosphosiderite’s rarity, it’s a relatively affordable crystal. 

Rough phosphosiderite will only cost you between you $0.04 to $0.10 per gram, more or less. Some higher-end pieces can vary between $0.24 to $083 per gram.

Phosphosiderite carvings, like phosphosiderite towers, spheres, clouds, and other shapes, are very popular and generally vary in price between $20 to $80. 

More intricate or higher-quality pieces can average around $90 to $200 but have garnered prices as high as $900. 

Along with the mineral being a bit rare, specimens aren't usually consistent in appearance — so you’re more likely to find phosphosiderite jewelry for sale by independent designers rather than chain jewelry stores

Faceted phosphosiderite bracelets and necklaces can generally be found for around $4 to $20. Higher-end pieces can fetch prices as high as $1300. 

Phosphosiderite cabochons generally range between $0.25 to $1.96 per carat, for low to mid-quality pieces. Higher quality cabochons generally sell for about $3.56 to $5 per carat.

Getting your crystals is just the first step. You’ll need to master proper gemstone care to ensure your phosphosiderite lasts forever!

Phosphosiderite Care and Maintenance

With phosphosiderite grading 3.5 to 4 on the Mohs scale, the mineral is quite soft. It’s also quite brittle so you’ll want to handle it carefully.

To clean your phosphosiderite stones, carefully rinse them with cool to room temperature water, mild soap, and a soft, non-abrasive cloth or soft-bristled brush. Dry it gently and thoroughly before storing it in a cool, dry place.

Avoid your phosphosiderite coming into contact with:

• Heat

• Harsh cleaners

• Abrasive chemicals

• Ultrasonic cleaners

• Harder minerals

As a delicate mineral, you’ll want to opt for phosphosiderite jewelry with protective settings. Always remove your jewelry before any rigorous or impact-prone activities.

Although it has some potential for aluminum toxicity, phosphosiderite is safe to handle. However, you should never use it in crystal elixirs, consume, or ingest it in any way.
