Turquoise
The Stone of Friendship. A guide to its geology, origins, character, and how to choose one for your collection.
The Stone of Friendship
Turquoise is one of the oldest gemstones known to history, valued across cultures from ancient Egypt to the Persian empire to the American Southwest for its distinctive sky-to-sea-blue colour.
Gemologically, turquoise is described as opaque, with a waxy to subvitreous luster — qualities that shape how it catches and carries light once cut. Its colour comes from copper (blue) and iron (green tones), and a Mohs hardness in this range calls for a little extra care — pendants, earrings, and occasional-wear rings suit it better than an everyday ring.
A Gem of Three Continents
Few stones appear in as many distinct ancient traditions as turquoise. In ancient Egypt, turquoise was mined in the Sinai peninsula and used in jewellery, amulets, and inlay work for thousands of years — most famously in the burial mask of Tutankhamun, where turquoise sits alongside lapis lazuli and carnelian. In Persia, turquoise from the Nishapur mines became a symbol of royalty and protection, set into crowns, jewellery, and architectural tilework across centuries of Persian art.
Independently, turquoise held deep significance among Native American peoples of the Southwestern United States, where it was worked into jewellery, ceremonial objects, and trade goods long before European contact — a tradition that continues today in the distinctive silver-and-turquoise jewellery associated with Navajo, Zuni, and Hopi craftspeople. In Tibet and across the Himalayas, turquoise has similarly long been worn for protection and is woven into traditional dress and ceremonial objects. This combination of independent traditions across Africa, the Middle East, the Americas, and Asia makes turquoise one of the most culturally widespread gemstones in human history.
Where Turquoise Comes From
Vibrant Colour & Texture, Mine by Mine
The benchmark for clean, uniform colour: a bright, slightly powdery sky-blue with little to no visible matrix at all. Closed to mining since 2012, so existing material is increasingly scarce — its smooth, almost matte texture and consistent colour make it instantly recognisable.
A livelier, more textural look — bright blue-to-blue-green colour threaded with fine, dark, web-like matrix veining. The contrast between the vivid body colour and the spidery dark lines gives Sonoran turquoise a distinctive, almost marbled texture.
The most saturated and "pure" blue in the trade — an intense, slightly greenish "robin's egg" colour with a smooth, glassy-looking surface and minimal matrix, historically considered the gold standard against which all other turquoise is compared.
Typically the most textured of the four — a deeper, more blue-green body colour with bold, dark matrix veining running through it in dramatic patterns. This rugged texture, combined with its ceremonial significance, gives Tibetan turquoise a distinctly earthy, weathered character compared to the smoother American and Persian material.
Firoza — Jupiter's Stone
In Indian Vedic astrology (Jyotish Shastra), turquoise is known as Firoza and is associated with Guru (Jupiter).
Firoza
In Vedic tradition, turquoise (Firoza) is associated with Jupiter and is sometimes worn as an accessible alternative to Yellow Sapphire, believed to support wisdom, communication, and good fortune.
How Turquoise Is Graded
Quality in turquoise is generally assessed across colour, clarity, cut, and carat weight — with colour and overall character typically the dominant factors in value.
What a Lab Report Confirms
A lab report identifies the species, describes colour, and discloses any treatment. Turquoise is frequently stabilised (treated with resin) to improve durability and colour-fastness — this is common and should be disclosed; untreated, high-grade material is rarer and more valuable.
Natural, Ethical, Jaipur-Sourced
Every turquoise in the Paraiso Jewels vault is described accurately as to its natural or treated status on its label. We source through Jaipur's gem market — one of the world's oldest and most concentrated coloured-stone trading centres — and our stones can be verified at GTL Jaipur, the region's principal gem testing authority.
On request, each piece can be accompanied by documentation covering weight, dimensions, and treatment status. If you have questions about the origin or treatment of a specific stone, contact us via WhatsApp or email and we'll provide full details.
