Earliest traces
Fragments of high-quality turquoise found in tombs in Sinai’s el-Qaa region are perhaps the earliest evidence of turquoise being mined, according to the Metropolitan Museum of Art.
Gemstone Story — 02 / The Caravan Edit
Turquoise
Turquoise is one of the oldest gemstones people have ever worn. Fragments found in tombs in Sinai are perhaps the earliest evidence of it, and the ancient Egyptians had a word for it, mefkat, that also meant joy.
Its name is a travel story. Mined in Persia, it reached Europe through Turkish lands, and Europe named it for the last hands it passed through: the Turkish stone.
Ours is Sleeping Beauty turquoise, from a mountain near Globe, Arizona, that looks like a woman asleep on her back. It is known for a clear sky blue with almost no matrix. The mine closed around 2012, so every stone from it was dug before that.
We named her Sarai, from the Persian word for a caravan’s inn: the place where travellers rest, trade stories and set out again.
A camel for the road. A clover for the luck. An open charm for the journey still to come.
Sarai. The road can wait.
Why Wear It
What wearers traditionally look for in this stone
Long before it was catalogued as a mineral, turquoise was worn for what it was believed to bring. Here is that tradition, told honestly, as belief and not as gemological fact.
Protection & Safe Passage
- Turns away the evil eye: In Persian tradition, turquoise was set on turbans, often among pearls, to guard the wearer against it.
- Worn as a safeguard: In ancient Persia it was worn at the neck or wrist as protection against harm.
- A talisman through the ages: Carried by royalty, warriors and shamans as a source of protection.
- A promise against hardship: The Persian scholar al-Qazwini wrote that whoever wore and sealed with a turquoise would never know poverty.
Good Fortune & Joy
- Joy, in the oldest word for it: Ancient Egyptians called turquoise mefkat, a word that also means joy and delight.
- Believed to bring luck and wealth: Many cultures have worn it to invite good fortune and prosperity.
- A stone of fortune in Tibet: Long regarded there as a stone of health, good fortune and protection.
- A gem fit for a god: Aztec tradition tells of Montezuma offering turquoise to Cortés, believing him to be Quetzalcoatl, whose favourite gem it was.
Calm & Connection
- Joins sky and sea: Native American traditions hold that turquoise opens a direct connection between the sky and the water.
- Lifts a heavy mood: Modern crystal tradition suggests wearing turquoise when spirits are low.
- A gentle daily companion: A popular choice in modern crystal practice for a calm, grounded everyday stone.
Birthstone & Gifting
- December’s birthstone: Turquoise is the traditional birthstone for the month of December.
- An anniversary gem: It is also the traditional gem of the 11th wedding anniversary.
The associations below reflect traditional and spiritual beliefs held by wearers of turquoise over time. They are not medical claims, and are not a substitute for professional medical or mental health advice.
01 — The Stone
The stone that named a colour
Turquoise is one of the few gems whose name became a colour. Its blue comes from copper, and iron pulls it towards green, which is why no two stones are quite alike.
Some gemstones are known for their sparkle. Turquoise is known for its sky.
Turquoise is opaque and waxy rather than brilliant, judged on the evenness of its colour, the smoothness of its texture and how little matrix runs through it. Sleeping Beauty is famous for exactly that: a clean, clear blue.
People have prized this colour on every inhabited continent. Native peoples of the American Southwest have worn turquoise for thousands of years, and the Mixtec-Aztec set it into mosaic masks between AD 1400 and 1521.
It is also a gentle stone. Turquoise is porous, so perfume, lotions, sweat and heat can dull its colour. Put it on last and take it off first, and it will stay beautiful for years.
02 — Origin
Seven thousand years, one blue
Turquoise’s history runs from the tombs of Sinai, along the roads of Persia, to a mountain in Arizona and a mine that is now closed.
Egypt’s ladders of turquoise
Egyptians worked the Sinai deposits at Wadi Maghareh and Serabit el-Khadim, a region they called the “Mining Country” and the “Ladders of Turquoise.” Even so, the stone stayed rare in Egypt.
The Turkish stone
Persia’s Nishapur mines supplied some of the finest turquoise of the age. It reached Europe through Turkish lands, and the French named it pierre turquoise: the Turkish stone. The word entered English in the 1560s.
Sleeping Beauty
Near Globe, Arizona, a claim first staked for copper and gold became one of the Southwest’s most famous turquoise mines in the 1970s. It was named for a nearby mountain shaped like a woman sleeping on her back, and rising costs closed it around 2012.
A finite blue
Turquoise is still mined in Iran, China and the American Southwest, but every Sleeping Beauty stone on the market was mined before that mine closed.
“A stone this old deserves more than a pretty story. It deserves a true one.”
03 — Look Closer
How to tell turquoise from its lookalikes
Visual clues can help you understand a stone, but they do not replace professional identification. For valuable pieces, independent laboratory testing is the safest way to confirm species and treatment.
Turquoise is imitated more often than most gems, and good imitations can fool the eye. Colour, matrix and texture are useful clues, but treatment status and origin are best confirmed with documentation.
010
Expect a little variation
Natural turquoise ranges from pale blue through sky blue to blue-green, and its properties vary from stone to stone. A colour that is unnaturally vivid and perfectly uniform deserves a closer look.
011
Read the matrix
Fine veins of brown or black rock, called matrix, are normal in turquoise, and Sleeping Beauty is prized for having very little. Be aware that matrix patterns can be imitated, so a pattern alone proves nothing.
012
Ask about treatment
Turquoise is commonly treated, most often by stabilisation, to improve its colour and durability. Treatment is acceptable when it is disclosed. Ask the seller to state it plainly.
013
Beware of lookalikes
Dyed howlite and magnesite are the most common imitations, and reconstructed turquoise is made from pulverised stone. Plastic and glass lookalikes also exist.
014
Request laboratory documentation
There are few non-destructive ways to test turquoise at home. For a significant purchase, an independent gemological report is the reliable way to confirm species and treatment.
04 — Rarity
Why Sleeping Beauty cannot be mined again
The rarity is not simply the name. It is a mine that has closed, a colour that is hard to match, and a supply that cannot grow.
The real rarity is the supply
Gem-quality turquoise is uncommon. Lower-quality material is softer and more porous, and is often treated to make it durable enough to wear.
The mine has closed. Rising costs ended mining at Sleeping Beauty around 2012, and every stone sold from it was mined before then.
Provenance matters. A famous mine name is not proof of origin, so ask for documentation and an independent report where the origin is important to you.

05 — The PEHRO Perspective
Why this stone belongs here
Blue is the invitation. The journey is the signature.
A
A story should be as honest as it is beautiful
Treatment, origin and imitation are part of a gemstone’s story, not footnotes to it. We tell all of it.
B
We separate fact from belief
Hardness, formula and refractive index belong to science. Evil-eye charms and lucky stones belong to culture. We keep the two apart so you can enjoy both.
C
The stone must earn its place
Sleeping Beauty’s clear, even sky blue is rare enough to carry a design on its own. In Sarai it needs only silver and a camel to say the rest.
D
The journey stays PEHRO
Turquoise brings the colour and the history. The camel, clover and open charms in 925 silver, and the restraint around them, are ours.

06 — Provenance
Sourcing & certification
The story of a natural gemstone should include what can be documented about the individual stone, not assumptions made from its name alone.
Sourcing
Sleeping Beauty turquoise comes from a single mine that closed around 2012, so origin matters. PEHRO discloses the sourcing information documented for the stones in each piece, rather than making a blanket claim.
- Origin disclosed where documented
- Treatment status disclosed where known
- Stone selection based on colour, evenness and finish
Certification
An independent gemological lab certificate can be added to gemstone pieces at checkout, so you can confirm what your stone is.
- Species identification
- Treatment status
- Origin assessment where the lab supports it
This page is for educational purposes. Gemological characteristics, treatment status and origin should be confirmed for the individual stone where relevant. Traditional or metaphysical associations are presented as beliefs, not medical or scientific claims.
