 Tanzanite

Tanzanite is primarily found in Tanzania, specifically in the Merelani Hills near Mount Kilimanjaro. Its name is derived from its country of origin, and it is renowned for its striking blue and violet hues. The unique color range of tanzanite is caused by trace amounts of vanadium within the mineral structure of zoisite. The introduction of vanadium impurities during its formation leads to the blue and violet coloration characteristic of tanzanite. The exact composition and distribution of vanadium within the crystal lattice contribute to its distinct color variations, ranging from deep blue to intense violet, sometimes exhibiting pleochroism. Tanzania is the only known source of tanzanite, making it a rare and highly coveted gemstone in its natural, untreated form.

Tanzanite is a gemstone that is highly valued for its vibrant blue-violet colour.

               who discovered tanzanite

Tanzanite is a gemstone that is named after its country of origin, Tanzania. It was first discovered in 1967 in the Merelani Hills near the city of Arusha in northern Tanzania. The gemstone was found by a local Maasai tribesman named Ali Juuyawatu, who came across some blue crystals and brought them to a prospector named Manuel de Souza. Recognizing the uniqueness and beauty of the gemstone, d'Souza realized that it had the potential to become a valuable gemstone in the global market.

The discovery of tanzanite caused great excitement in the gemstone industry, and the gemstone was initially marketed as "blue zoisite." However, due to concerns that the name "zoisite" could be confused with "suicide," the name "tanzanite" was later adopted to highlight its Tanzanian origin. The gemstone gained popularity and quickly became sought-after for its vibrant blue-violet color and limited availability.

Since its discovery, tanzanite has remained closely associated with Tanzania, and the country is the primary source of this gemstone. The Merelani Hills, located in the Manyara Region of northern Tanzania, continue to be the main mining area for tanzanite. The gemstone's unique color and limited supply from this single location contribute to its rarity and desirability in the global gemstone market.

                 color of tanzanite

The color of tanzanite is a key characteristic that distinguishes it as a unique gemstone. Tanzanite is known for its vibrant blue-violet color, although the specific shade can vary. The gemstone's color is often described as a vivid violet-blue or deep cornflower blue. Under natural light, tanzanite typically exhibits deep blue tones. However, when viewed under incandescent light or from different angles, it can display violet or purplish hues.

Tanzanite's color is influenced by a phenomenon called pleochroism, which means it shows different colors when viewed from different angles. This pleochroic property is one of the distinctive features of tanzanite. It can exhibit different shades of blue, violet, and sometimes even burgundy, depending on the angle of observation.

The intensity and saturation of tanzanite's color can vary from gemstone to gemstone. The most valuable tanzanites are those with a deep and saturated blue-violet color. The color is an important factor in determining the quality and value of tanzanite, with more intense and vibrant colors being highly prized by collectors and enthusiasts.

It's worth noting that tanzanite's color can be enhanced through heat treatment to bring out its vivid blue or violet hues. Heat-treated tanzanite is widely accepted and valued in the gemstone industry. When purchasing tanzanite, it's important to ensure that the gemstone's color is natural or the treatment is disclosed, as natural, untreated tanzanite is considered rarer and valuable.

color variation

Tanzanite exhibits a range of color variations within its blue-violet spectrum. The primary color variations of tanzanite can be broadly categorized into three main hues: blue, violet, and bluish-violet. The specific shade and intensity of these colors can vary based on factors such as the quality of the gemstone, lighting conditions, and individual gemstone characteristics.

Within the blue range, tanzanite can display shades that range from a lighter, pastel blue to a deep, intense royal blue. The blue tanzanites are often highly sought after for their captivating and vibrant blue color.

In the violet range, tanzanite can showcase hues that range from light lavender to rich violet. These gemstones tend to have a more purplish appearance and can be quite mesmerizing.

The bluish-violet tanzanites combine elements of both blue and violet, resulting in a unique and captivating color. These gemstones exhibit a stunning blend of blue and purple tones, making them highly prized by collectors and enthusiasts.

It's important to note that the color appearance of tanzanite can vary depending on factors such as lighting conditions and the angle from which it is viewed. This pleochroic property adds to the allure of tanzanite, as it can exhibit different colors when observed from different angles.

Overall, the color variations of tanzanite contribute to its uniqueness and desirability, as individuals can choose gemstones that best align with their personal preferences and style

               rarest gemstones

Tanzanite is considered to be one of the best rarest gemstones in the world. Several factors contribute to its rarity:

1. Single Source: Tanzanite is found exclusively in one location, the Merelani Hills of northern Tanzania. Unlike many other gemstones that have multiple mining sources around the world, tanzanite's limited geographic origin adds to its rarity.

2. Limited Supply: The supply of tanzanite is relatively scarce. The mining operations in the Merelani Hills have encountered challenges in accessing new deposits, and the existing mines have been yielding diminishing quantities over time. This limited supply creates a sense of exclusivity and increases the gemstone's rarity.

3. Geological Formation: The geological conditions required for the formation of tanzanite are quite unique. It is formed through a process called metamorphism, which involves the transformation of existing minerals under high pressure and heat. The specific combination of elements and circumstances needed for tanzanite's formation is rare, further contributing to its scarcity.

4. Finite Availability: As tanzanite is a finite resource, there is a finite amount of gemstone available in the world. Over time, the known deposits of tanzanite may become depleted, making it increasingly challenging to obtain high-quality stones.

Due to its rarity, tanzanite is highly valued in the gemstone market. The combination of its limited supply, single-source origin, and unique color contributes to its allure and makes it a prized gemstone among collectors and enthusiasts.

 trichroism

Tanzanite is known for its trichroism, which is a characteristic that sets it apart from many other gemstones. Trichroism refers to the property of exhibiting three different colors when viewed from different angles. In the case of tanzanite, it displays different hues of blue, violet, and burgundy depending on the angle of observation.

When light enters a tanzanite gemstone, it is split into three different wavelengths due to the crystal's pleochroic nature. These three wavelengths correspond to the three primary colors observed in tanzanite: blue, violet, and red. As a result, tanzanite may appear predominantly blue when viewed from one angle, violet from another angle, and even show hints of burgundy or reddish tones from yet another angle.

This play of colors adds to the allure and visual interest of tanzanite. It gives the gemstone a dynamic and captivating quality, as its appearance can change depending on how it is viewed. Trichroism is particularly noticeable in larger tanzanite gemstones, where the different color zones can be more distinct.

It's important to note that the intensity and distribution of the colors can vary from stone to stone. Some tanzanites may exhibit a more pronounced trichroic effect, while others may show a subtler variation in colors. Nonetheless, trichroism is a characteristic feature of tanzanite and contributes to its overall beauty and uniqueness.

               Hardness of Tanzanite

Tanzanite has a hardness of approximately 6.5 to 7 on the Mohs scale of mineral hardness. The Mohs scale is a widely used system that measures the relative hardness of minerals based on their ability to resist scratching.

A hardness of 6.5 to 7 indicates that tanzanite is moderately hard. It is harder than many common household items and materials like glass, fingernails, and copper. However, it is softer compared to gemstones like sapphires and diamonds, which have higher rankings on the Mohs scale.

The hardness of tanzanite makes it suitable for use in jewelry, such as rings, earrings, necklaces, and bracelets. However, it is important to handle tanzanite with care to avoid scratching or other damage. It is recommended to store tanzanite jewelry separately from harder gemstones to prevent potential abrasion.

When wearing tanzanite jewelry, it is advisable to remove it before engaging in activities that may subject the gemstone to rough surfaces or potential impact. Regular cleaning and gentle handling will help maintain the gemstone's beauty and prevent unnecessary wear.

Overall, while tanzanite is not as hard as some other gemstones, proper care and maintenance can ensure its longevity and preserve its visual appeal.
