Turquoise is one of the world’s oldest and most beloved gemstones, instantly recognizable by its soothing blue-green hues. Worn by royalty, shamans and artisans, traders and travellers. Turquoise has crossed continents and centuries as a symbol of protection, prosperity, healing, and spiritual connection. Its history is rich and intriguing and I would love to share some of it here.
What Is Turquoise?

Turquoise is a hydrated phosphate of copper and aluminium, formed in arid regions where water percolates through and slowly alters copper-rich sedimentary and igneous rocks. Its iconic colour—ranging from white, sky blue to greenish teal and yellow—comes from copper and iron. The opacity and relative softness of the stone has make it especially suited for carving, inlay, and bold jewellery designs throughout history. It has always been cherished not just for rarity, but for its symbolic power and visual impact.
Historical significance.
Ancient Egypt (c. 3000 BCE)
The earliest known turquoise mines were located in the Sinai Peninsula and worked by the ancient Egyptians over 5,000 years ago. The Egyptians adored turquoise which was used extensively in jewellery. It adorns the burial mask of Pharaoh Tutankhamun, symbolizing rebirth and divine protection in the afterlife. Egyptians associated turquoise with the goddess Hathor, protector of miners and bringer of joy. Ancient Egyptians valued the highly priced turquoise so much that they were also the first in history to create imitations of the stone in the form of glazed faience (a type of ceramic).

Persia (modern-day Iran)
Persians were among the most influential users of turquoise. They believed that changing colour in a turquoise stone warned the wearer of danger or illness. Persian turquoise was often set into swords, crowns, and mosques—its colour symbolizing heaven on earth. Even today, Iranian turquoise is considered some of the finest in the world.
Ancient China
In China, turquoise was carved into decorative objects and ritual items. It symbolized wealth, status, and the harmony between heaven and earth, and was often used alongside jade.
Mesoamerica (Aztecs & Mayans)
In Central America, turquoise was highly sacred. The Aztecs used it in elaborate mosaics to decorate masks, shields, and religious artifacts. It symbolized fire, the sun, and divine authority.
Native American Jewellery
In North America, turquoise became central to Southwestern Native American jewellery. From the late 19th century onward, turquoise set in silver became a defining style of Native American craftsmanship that remains globally influential today.
Europe
During the Middle Ages, turquoise travelled to Europe along trade routes from Persia and the Middle East. The name “turquoise” itself comes from the French word turquois, meaning “Turkish,” since the stone entered Europe through Turkey. European nobility believed that turquoise would protect riders from falls, prevent poisoning and would bring harmony to marriages. The stone became especially popular in Renaissance and Victorian jewellery, often set into rings to convey loyalty and eternal love.
Where Is Turquoise Mined?
Today turquoise is mainly mined in the United States, Iran , China , and Mexico, with smaller deposits existing in Afghanistan, Chile, and parts of Central Asia. As natural turquoise is not that common, it commands a higher price and, due to this, there are many fakes, imitations and synthetic stones on the market, such as coloured howlite and magnesite. A unnatural evenness in colour and texture is a give away to recognise these fakes. It should also be noted that natural turquoise can be porous and soft and stones may be stabilized with resin to improve hardness and colour consistency. If the turquoise stone is stabilised this should be notified by the jeweller - if you have a suspicion its wise to ask.
Turquoise in Harmattan Jewellery designs.

In Harmattan Jewellery I consequently only use high quality genuine turquoise in the designs. I do this to to honour the connection of the designs to ancient art and because I love the texture and colour variations in natural stones, which give the jewellery character, make it unique and come to life. I predominantly use turquoise in the Egyptian Collection, which feature patterns and designs inspired by this ancient culture. Just like the ancient Egyptians, I favour combining the turquoise with dark blue lapis lazuli from Afghanistan and orange / red carnelian from India as well as gold.
The genuine high quality turquoise used predominantly come from Arizona, U.S.A..

I also on occasion have had the good fortune to acquire some ancient Hubei turquoise beads. In the photograph to the left you can see the marked difference in colour and texture compared to the American turquoise used in the Ra necklace above. Both types of turquoise are high quality and stunningly beautiful.
So to answer my leading question "Why Turquoise", the answer would have to be that few stones are so varied and yet recognisable, colourful and evoke such immediate associations and connections with different cultures, history and the ancient world.
