What Is Grossular Garnet?

Grossular Garnet is a mineral group that includes several gemstones such as Almandine, Pyrope, and Spessartine. It is often called the “Gooseberry Garnet” due to its green color and round shape, resembling the fruit. It can come in many colors, including green, yellow, orange, brown, and black.

 It is a durable gemstone with a hardness of 6.5-7.5 on the Mohs scale, making it suitable for everyday wear. It is mainly found in Madagascar, Tanzania, and Canada. It is commonly used in jewelry, including earrings, necklaces, bracelets, and rings. It is believed to have spiritual properties, including grounding, manifestation, and abundance. It is said to be a stone of prosperity and success.

How is Grossular Garnet Formed?

Grossular Garnet is formed in metamorphic and igneous rocks. It is a type of aluminum-calcium GarnetGarnet composed of calcium, aluminum, and silicate minerals. It is formed when magma or molten rock cools and crystallizes or when existing rocks are subjected to intense heat and pressure, causing the minerals to recrystallize and form new minerals.

The specific conditions that lead to the formation can vary but generally involve the presence of calcium-rich rocks such as limestone or dolomite and aluminum-rich minerals such as diopside or andradite. These minerals combine under the right conditions to form crystals, ranging in size from tiny grains to large, gem-quality specimens.

Formation of Grossular Garnet is a complex process that depends on various geological factors, including temperature, pressure, and the chemical composition of the surrounding rocks and fluids.

The name “Grossular” is derived from the Latin word “grossularia,” which means “gooseberry.” This name was given to the Garnet because of its green color, which resembles the gooseberry fruit.

 The term “garnet” itself comes from the Latin word “granatus,” meaning “grain” or “seed,” due to the resemblance of some garnets to pomegranate seeds.

Grossular Garnet Appearance

Grossular Garnet is a beautiful gemstone in various colors, including green, yellow, orange, brown, and black. The green variety is the most common and is often referred to as “Tsavorite” when it is of gemstone quality. The color can vary depending on the crystal structure’s amount of iron or chromium.

It has a vitreous to resinous luster, which gives it a sparkling and shiny appearance. It has a transparent to opaque transparency, depending on the quality of the specimen. It is a durable gemstone with a hardness of 6.5-7.5 on the Mohs scale, making it suitable for everyday wear. It has a specific gravity of 3.57-3.89, higher than most other gemstones.

Grossular Garnet can occur in different crystal habits, including dodecahedrons, trapezohedrons, and rhombic dodecahedrons. It can also occur as granular aggregates or massive formations. The crystal structure is cubic and has a refractive index of 1.734-1.759. The fracture is conchoidal to uneven, which can break in a curved or irregular pattern.

Varieties of Grossular Garnet

There are several different varieties of Grossular Garnet, which vary in color and composition. Some of the most common types include:

  1. Tsavorite: Tsavorite is a green type prized for its bright color and high clarity. It was first discovered in Tanzania in the 1960s and is now also in Kenya. Tsavorite is a relatively rare gemstone that is often used in high-end jewelry.
  2. Hessonite: Hessonite is a brown or orange variety often found in Sri Lanka, Brazil, and Tanzania. It is known for its warm color and is commonly cut into cabochons for use in jewelry.
  3. Hydrogrossular: Hydrogrossular is a green or pink variety with significant water in its crystal structure. It is found in California, New Zealand, and Siberia and is often used as a lapidary material.
  4. Mali Garnet: Mali Garnet is a rare variety first discovered in Mali in the 1990s. It is a yellow-to-green gemstone with a high refractive index, giving it a unique brilliance.
  5. Rosolite: Rosolite is a pink to the purple variety found in Mexico and the United States. It is commonly used as a decorative stone and is sometimes cut into cabochons for use in jewelry.

Grossular Garnet Value and Price

The value and price of Grossular Garnet can vary depending on several factors, including carat weight, cut, clarity, and color. Other factors that can affect the value include:

  • The quality of the specimen.
  • The rarity of the color or type.
  • The demand in the market.

Carat weight: Like other gemstones, the larger the piece, the more valuable it is. However, the price per carat remains relatively high in size, as it is a relatively abundant gemstone.

Cut: The cut can have a significant impact on its value. A well-cut stone with good proportions and symmetry will have better light performance. It will therefore be more valuable than a poorly cut stone.

Clarity: The Garnet can have inclusions, such as minerals, fractures, or bubbles, affecting its transparency. Generally, the more transparent and free of inclusions the gemstone is, the more valuable it is.

Color: The color can vary greatly; certain colors are more valuable than others. For example, the vivid green color of Tsavorite is highly valued. In contrast, the brown or orange color of Hessonite is less valuable.

In addition to these factors, the quality of the specimen and the rarity of the color or type can also affect the value and price. It is a relatively affordable gemstone, with prices ranging from a few dollars per carat for lower-quality specimens to several hundred dollars for high-quality Tsavorite or Mali Garnet.

How Can You Tell if Grossular Garnet Is Real?

Several tests can be performed to verify the authenticity.

  1. Visual inspection: First, you can examine the gemstone for any visible imperfections, such as air bubbles or cracks. The real sample is typically free of visible inclusions, while synthetic or imitation stones may have obvious imperfections.
  2. Hardness test: The stone has a hardness of 6.5 to 7.5 on the Mohs scale, meaning it can scratch glass. You can perform a scratch test by scratching the gemstone with glass. If the gem scratches the glass, it is likely a real piece.
  3. Refractive index test: The stone has a refractive index of 1.73 to 1.75, meaning it bends light in a specific way. A refractometer can measure the refractive index of the gemstone and compare it to the known values for the real one.
  4. UV light test: Some types, such as Hessonite, may fluoresce under UV light. You can shine a UV light on the gemstone to see if it emits any fluorescence.
  5. Specific gravity test: The Garnet has a specific gravity of 3.57 to 3.89, which can be measured using a specific gravity test. By comparing the gemstone’s weight in the air to its weight in water, you can calculate its specific gravity and compare it to the known values.

A combination of these tests can help determine if a sample is real or not. It is also recommended to purchase gemstones from reputable dealers who can provide certificates of authenticity and disclose any treatments or enhancements that may have been applied to the gem.
