However, the stones from this island were later discovered to be Peridot, but the name stuck. The color blue was traditionally not a natural color for Topaz, but the stone can be treated to create stunning and durable blue shades.

Turquoise is a beautiful gemstone that has been treasured for thousands of years. It has a rich history of cultural significance and is widely used in jewelry and various forms of art. It is characterized by its unique blue to green color, which ranges from sky blue to teal or even darker green hues. 

It has a moderate hardness of around 5 to 6 on the Mohs scale, which means it is relatively durable but not as hard as gemstones like diamonds or sapphires. Turquoise is a hydrous phosphate mineral, primarily composed of copper and aluminium.

Turquoise is often associated with Native American and Southwest American cultures but is cherished worldwide for its captivating color and natural allure.

Meaning of Turquoise

The word "turquoise" has an interesting etymology that traces back to its ancient origins. The term has been used for both the gemstone and the color. 

The word "turquoise" has its roots in the Old French word "turqueise," which means "Turkish stone." This Old French term was derived from the Latin word "turquois," which also referred to the gem.

The reason behind calling this gem "Turkish stone" in Old French and Latin is because, during medieval times, the stone was imported to Europe from Turkey (then known as the Ottoman Empire) through trade routes. 

Europeans associated the stone with Turkey because it was often brought to Europe by Turkish merchants. While the stone was indeed traded through Turkey, the actual origin of the turquoise gem is believed to be in ancient Persia (present-day Iran). The region has been a significant source of turquoise for thousands of years, and it held cultural and spiritual importance in various civilizations in the Middle East and Central Asia.

Over time, the term "turquoise" became widely adopted and accepted in the English language, referring to both the gemstone and the color that resembles it. As a color, "turquoise" describes a shade of blue-green that reflects the color of the gemstone.


History of Turquoise

Turquoise has a long history that can be traced back to ancient civilizations in Egypt, Mesopotamia, Persia (modern-day Iran), and China. Archaeological evidence suggests that turquoise was used as early as 5,000 BCE in jewelry, amulets, and decorative artifacts.

Turquoise was highly prized by the ancient Egyptians and was associated with the sky and water. It was often used to craft jewelry, amulets, and ceremonial objects. The stone was also believed to have protective and healing properties and was used in burial rituals to protect the deceased.

The Persians, particularly during the Sassanian Empire (224-651 CE), held turquoise in high regard. It was used in various forms of art and jewelry, including elaborate turquoise-inlaid metalwork and mosaics. The Persians believed turquoise could protect them from evil and bring good fortune.

In the Americas, turquoise held significant cultural and spiritual value for various indigenous tribes. Native American cultures, such as the Navajo, Pueblo, Zuni, and Hopi, used turquoise in their jewelry, pottery, and religious ceremonies. Turquoise was often associated with protection, fertility, and communication with the spirit world.

Turquoise became known in Europe through trade routes and was used in jewelry and religious artifacts. During the Renaissance, it was popular in royal courts and among wealthy patrons.

The trade routes of the Silk Road played a vital role in the dissemination of turquoise throughout Asia, Europe, and the Middle East. The Ottoman Empire was a significant hub for the trade of turquoise, leading to its prominence in Turkish jewelry and decorative arts.

Turquoise saw a resurgence in popularity during the 19th century, particularly in the United States. Native American turquoise jewelry gained popularity, and it became a sought-after gemstone in Western fashion and art.

Turquoise continues to be a popular gemstone in contemporary jewelry design, and its historical significance still holds appeal for collectors and enthusiasts alike. High-quality turquoise is mined in various locations worldwide, including the United States (e.g., Arizona, New Mexico, Nevada), Iran, China, Mexico, and other countries.

Geological Properties of Turquoise 

Geologically, turquoise is a hydrous phosphate mineral composed primarily of copper and aluminum. Turquoise has a chemical formula of CuAl6(PO4)4(OH)8·4H2O. This composition makes it a hydrous phosphate, meaning it contains water molecules in its structure.

The most notable characteristic of turquoise is its distinct blue-green color, which ranges from sky blue to greenish-blue. The color is influenced by the presence of copper and iron impurities within the mineral.

Turquoise is relatively soft on the Mohs scale of mineral hardness, typically ranging from 5 to 6. This means it is susceptible to scratching and abrasion, making it less durable compared to other gemstones like sapphires or diamonds.

Turquoise is commonly formed in arid, semi-arid, or desert environments through the interaction of groundwater containing dissolved copper with aluminum-rich rocks. Over time, this process results in the deposition of turquoise minerals in veins, cavities, or fractures in the host rock.

In its natural form, turquoise is often found embedded within its host rock, known as the matrix. The matrix can be various types of rock, such as rhyolite, limonite, or sandstone, and it adds to the overall appearance and uniqueness of the gemstone.

Turquoise has a waxy to sub-vitreous luster, which gives it a smooth, polished sheen when cut and polished.Turquoise is typically opaque, although some high-quality specimens may exhibit slight translucency.

Turquoise deposits are found in several regions around the world, including the southwestern United States (e.g., Arizona and New Mexico), Iran, Afghanistan, China, and other parts of the Middle East.

Natural turquoise can be porous and vulnerable to changes in color and stability due to environmental factors or chemical reactions. As a result, some turquoise may undergo stabilization processes, such as impregnation with resins or other substances, to enhance its durability and appearance.

Tanzanite is a stunning blue-violet gemstone that is highly valued for its unique color and rarity. It belongs to the mineral species zoisite and is one of the most sought-after gemstones in the world. 

Tanzanite's color ranges from blue to violet-blue, with some stones displaying a deep blue hue. It is pleochroic, meaning it can exhibit different colors when viewed from different angles. 

Tanzanite is considered a rare gemstone. The only known source of tanzanite is the Mererani Hills in northern Tanzania, making it a limited and valuable find.  Tanzanite is usually transparent, with few inclusions. High-quality tanzanite stones with excellent clarity are highly prized. It is often faceted to maximize its brilliance and showcase its color. 

Tanzanite has a moderate hardness of 6 to 7 on the Mohs scale, which makes it relatively durable for jewelry purposes but requires careful handling to prevent scratching or chipping.  

Most tanzanite undergoes heat treatment to enhance its color. The heat treatment process can produce the desirable blue and violet shades for which tanzanite is known. Tanzanite is a popular gemstone for various jewelry pieces, including rings, pendants, earrings, and bracelets.

Meaning of Tanzanite

The term "tanzanite" has a relatively recent etymology, dating back to the 20th century. Tanzanite is a variety of the mineral zoisite. The name "tanzanite" was given to this gemstone due to its exclusive source in Tanzania, East Africa.

The gemstone's name "tanzanite" was proposed by Tiffany & Co. to reflect its exclusive source in Tanzania. It was derived from the country's name, combining "Tanzania" with the suffix "-ite," which is commonly used for minerals. 

The name "tanzanite" gained widespread recognition and acceptance in the gem and jewelry industry, eventually becoming the standard term for this beautiful blue-violet gemstone. Tanzanite's rarity, captivating color, and unique origin have contributed to its popularity as a precious gemstone in the jewelry market. 


History of Tanzanite

The history of tanzanite is relatively short compared to many other gemstones. Tanzanite was discovered in 1967 and quickly gained popularity for its stunning blue-violet color and rarity. Tanzanite was first discovered in the Merelani Hills near Arusha in northern Tanzania. The exact date of the discovery is often attributed to July 7, 1967, when a local Maasai tribesman named Ali Juuyawatu found transparent, blue crystals on the ground. He informed a local fortune hunter and gemstone prospector, Manuel d'Souza, about the discovery.

At first, tanzanite was thought to be a rare form of sapphire due to its blue color. However, it was later identified as a distinct mineral species and named "blue zoisite" by the renowned gemologist Henry Platt, who was also the president of Tiffany & Co. (the famous jewelry company). In 1968, Tiffany & Co. realized that the name "blue zoisite" might be confused with the word "suicide." To avoid any negative connotations, they decided to rename the gemstone "tanzanite" after its country of origin, Tanzania. The name change was a marketing strategy that also highlighted the gem's unique geographic origin. 

Tanzanite's vibrant blue-violet color and limited supply quickly caught the attention of the international gemstone market. The gemstone became highly sought after, and its popularity soared. Tiffany & Co. played a significant role in promoting tanzanite and introducing it to the global market. 

Unlike many other gemstones, tanzanite is found in only one location in the world - the Merelani Hills in Tanzania. This limited supply, coupled with its striking color, contributed to its exclusivity and desirability. In 2002, tanzanite was recognized as an official December birthstone, alongside turquoise and zircon. This recognition further increased its popularity and demand. 

Tanzanite's unique and captivating color, combined with its limited availability, has made it a highly prized gemstone in the world of jewelry and a significant contributor to Tanzania's economy. As with any gemstone, the value and allure of tanzanite remain subject to fluctuating market trends and supply considerations.


Geological properties of Tanzanite

Tanzanite is a calcium aluminum silicate mineral and belongs to the epidote group. Its chemical formula is Ca2Al3(SiO4)3(OH).

The most desirable tanzanite gemstones exhibit a deep blue to violet-blue color. This coloration is attributed to the presence of vanadium, which acts as a chromophore, absorbing certain wavelengths of light and imparting the characteristic blue hue.

Tanzanite exhibits trichroism, which means it shows different colors when viewed from different crystallographic directions. The three colors typically seen are blue, violet, and burgundy, and the intensity of these colors can vary depending on the orientation of the crystal.

On the Mohs scale of mineral hardness, tanzanite scores around 6.5 to 7.0. While it is harder than many common materials, it is still softer than gemstones like sapphire and diamond, making it susceptible to scratching and chipping. Tanzanite has distinct cleavage in one direction, which means it can split along specific planes. This property makes the gemstone somewhat fragile and requires careful handling during cutting and setting

Tanzanite is typically transparent to translucent, allowing light to pass through the gemstone and creating a pleasing play of color.

Tanzanite is considered one of the rarest gemstones in the world. Its exclusive source in northern Tanzania makes it particularly valuable.

Blue Zircon

Blue zircon is a gemstone known for its stunning blue color. Zircon is a mineral belonging to the group of nesosilicates and is often used as a gemstone in jewelry. It comes in a variety of colors, but blue zircon is one of the most popular and sought-after colors. 

As the name suggests, blue zircon exhibits a range of blue shades, from pale blue to vibrant blue. The color is typically caused by trace amounts of certain elements, such as iron and titanium. 

Blue zircons can occur naturally, but synthetic zircons are also available. Natural blue zircons are more valuable and desirable than their synthetic counterparts.

It is important to note that zircon should not be confused with cubic zirconia, which is a synthetic diamond simulant and not a natural gemstone like zircon.

Meaning of Blue Zircon

The word "zircon" comes from the Arabic word "zargun," which means "golden-colored." Zircon is a silicate mineral with a chemical formula of ZrSiO4. 

It's a common gemstone and comes in various colors, including colorless, yellow, orange, brown, green, and blue. The color in blue zircon is usually caused by trace impurities or heat treatment, which enhances the gem's color. 

So, "blue zircon" is simply a blue-colored variety of the zircon gemstone. The term has been in use for many years to describe this gemstone and its distinctive blue hue.


History of Zircon

Early civilizations, including those in ancient Mesopotamia and Egypt, valued zircon for its beauty and believed it to have mystical and healing properties. Blue zircon was not explicitly distinguished at this time, as natural zircon colors can vary from colorless to various shades of yellow, red, brown, and even blue.

During the Middle Ages, zircon gained popularity in Europe as a popular gemstone. It was often used in jewelry and religious artifacts. In the 16th century, blue zircon began to be mentioned separately in historical accounts. Zircon stones with blue hues became more sought after for their unique color, though they were still relatively rare compared to other gemstones of the time.

Zircon deposits were found in various parts of the world, including Southeast Asia (e.g., Cambodia, Myanmar, and Thailand), Sri Lanka, and parts of Africa. The famous "Star of Lanka" is a blue zircon mined in Sri Lanka, known for its exceptional size and beauty.

In the early 20th century, researchers discovered a method to synthesize zircon in the laboratory. This opened the possibility of producing zircons in various colors, including blue. Synthetic blue zircons became more common and affordable than their natural counterparts.

Today, blue zircon continues to be a popular gemstone in the jewelry industry. Natural blue zircons are relatively rare, which adds to their allure and value. However, synthetic blue zircons remain readily available and are widely used in various jewelry designs.

It's also important to note that the blue color in zircon is often the result of heat treatment. Natural zircons may exhibit a brownish or greenish hue, and applying controlled heating can transform them into the desired blue color. Heat-treated blue zircons are widely accepted in the gemstone market and are still valued for their beauty and charm.

Certain rare and high-quality blue zircon specimens can be collectible and valuable to gemstone enthusiasts and collectors.


How to care for Blue Zircon

Blue zircon is relatively hard, but it can still chip or crack if subjected to a hard blow. Avoid wearing your blue zircon jewelry during activities where it might encounter hard surfaces or other gemstones.

While blue zircon has a decent hardness, it can still be scratched by harder materials. Store your blue zircon jewelry separately from other jewelry, ideally in a soft cloth or a padded jewelry box to prevent scratching.

Avoid exposing your blue zircon to harsh chemicals, such as household cleaners, cosmetics, and hairsprays. These chemicals can damage the gemstone and affect its color and clarity.

Take off your blue zircon jewelry during physical activities, especially sports and exercise. This helps to prevent any accidental damage.

To clean your blue zircon, use a mild soap with warm water and a soft brush or cloth. Gently scrub the gemstone to remove any dirt or residue. Avoid using harsh chemicals or ultrasonic cleaners, as they can damage the stone.
