Turquoise Howlite is a captivating gemstone renowned for its striking resemblance to natural turquoise. However, it’s important to note that Turquoise Howlite is not a genuine turquoise stone; instead, it is a white or light gray mineral known as howlite that has been dyed to mimic the appearance of turquoise.

Turquoise Howlite

Definition and Composition: Howlite is a borate mineral that belongs to the same family as other borate minerals like borax and ulexite. Its chemical composition is calcium borosilicate hydroxide (Ca2B5SiO9(OH)5). Howlite is naturally white or gray with veins or patches of black matrix, which gives it a distinctive appearance. To create Turquoise Howlite, the naturally occurring howlite is often dyed to replicate the vibrant blue-green hues of turquoise. This process allows for the creation of affordable jewelry and decorative items with a turquoise-like appearance.

Origin and History: Howlite was first discovered in Nova Scotia, Canada, in the mid-19th century by geologist Henry How. It was named after him in recognition of his contributions to the field of mineralogy. While howlite itself has been known since the 19th century, the practice of dyeing it to resemble turquoise became popular later on.

The exact origins of Turquoise Howlite as a gemstone are a bit more ambiguous due to its manufactured nature. However, its popularity surged in the mid to late 20th century as an affordable alternative to genuine turquoise. Jewelers and artisans appreciated its similarity to turquoise while being more economical and readily available.

In contemporary times, Turquoise Howlite continues to be prized for its striking appearance and versatility in jewelry making. It is often used in beaded necklaces, bracelets, earrings, and other accessories. Additionally, it finds its place in ornamental carvings and sculptures due to its ease of shaping and dyeing. Despite not being a natural gemstone, Turquoise Howlite has carved out its niche in the world of fashion and decorative arts, offering an accessible option for those who admire the beauty of turquoise but seek a more budget-friendly alternative.

Significance in Jewelry Making and Ornamental Use

Physical Characteristics

Turquoise Howlite

The physical characteristics of Turquoise Howlite encompass its appearance, properties, and composition:

  1. Color: Turquoise Howlite typically exhibits a vibrant blue-green coloration that closely resembles natural turquoise. However, the color may vary slightly depending on the dyeing process and the quality of the howlite used. The hue can range from light turquoise to deeper shades of blue-green.
  2. Texture: Turquoise Howlite has a smooth and often polished texture, especially when used in jewelry making. However, in its natural form, howlite may have a slightly porous or granular texture.
  3. Veining: Similar to natural turquoise, Turquoise Howlite may feature veining or matrix patterns that mimic the appearance of genuine turquoise. These dark lines or patches contrast with the vibrant blue-green background, adding depth and character to the stone.
  4. Transparency: Turquoise Howlite is typically opaque, meaning that it does not allow light to pass through. This opacity contributes to its vivid color and enhances its resemblance to genuine turquoise.
  5. Hardness: Howlite has a Mohs hardness of around 3.5 to 6.5, making it relatively soft compared to other gemstones. While this hardness level provides sufficient durability for jewelry making and ornamental use, Turquoise Howlite may still be susceptible to scratching and chipping with excessive wear or rough handling.
  6. Luster: Turquoise Howlite exhibits a waxy to vitreous luster, depending on its surface finish and quality. When polished, it can display a glossy sheen that enhances its visual appeal.
  7. Density: The density of Turquoise Howlite varies depending on its composition and the presence of impurities. On average, it has a density ranging from 2.53 to 2.59 grams per cubic centimeter.
  8. Structure: Turquoise Howlite belongs to the monoclinic crystal system and typically forms in irregular masses or nodules. Its crystal structure is characterized by intersecting cleavage planes and a prismatic habit.

These physical characteristics collectively contribute to the unique appearance and allure of Turquoise Howlite, making it a popular choice for jewelry making, decorative arts, and ornamental use.

Geological Formation

Turquoise Howlite

Turquoise Howlite, like natural howlite, forms through a process known as hydrothermal alteration in boron-rich environments. Here’s a brief overview of the geological formation of howlite and subsequently Turquoise Howlite:

  1. Formation of Howlite: Howlite is a borate mineral that typically forms in boron-rich sedimentary deposits. These deposits are often associated with volcanic activity and hydrothermal alteration zones. During hydrothermal processes, hot water containing dissolved minerals percolates through the surrounding rocks, depositing minerals and altering existing minerals in the process.
  2. Boron-Rich Environments: Boron-rich environments, where howlite forms, are often found near volcanic regions or in sedimentary basins associated with volcanic activity. Boron is introduced into the environment through volcanic gases and hydrothermal fluids, where it reacts with other elements to form borate minerals like howlite.
  3. Precipitation and Crystallization: As the hydrothermal fluids cool and interact with the surrounding rock formations, conditions become favorable for the precipitation and crystallization of howlite. The specific mineral composition of the surrounding rocks, as well as factors such as temperature, pressure, and pH, influence the formation of howlite crystals.
  4. Dyeing Process (for Turquoise Howlite): After howlite is extracted from the earth, it undergoes a dyeing process to achieve the vibrant blue-green coloration characteristic of Turquoise Howlite. This process typically involves immersing the howlite in a solution containing dyes or pigments, which are absorbed into the porous structure of the mineral. The howlite is then heated to set the color, resulting in Turquoise Howlite.

It’s important to note that Turquoise Howlite is not a naturally occurring mineral; rather, it is a dyed form of howlite designed to mimic the appearance of turquoise. While the geological formation of howlite follows the processes outlined above, the dyeing of howlite to create Turquoise Howlite is a human-made process aimed at enhancing its aesthetic appeal for use in jewelry making and decorative arts.
