Garnets are one of the oldest known gemstones, prized since antiquity for their beauty and hardness. While typically known as a red gemstone, garnets actually come in a wide variety of colours, depending on their species. They are found worldwide and in 21 US states, including Montana and Idaho. In Montana, garnets were delivered downstream by the Ruby River and its tributaries, and they can be found in the Greenhorn Mountains. In Idaho, the Emerald Creek Garnet Area near St. Maries offers rockhounds the chance to dig up their own star garnets. Panning is one of the two main ways that garnets are found, and they are frequently found in creeks. They are usually small crystals, and finding them usually takes more work than just strolling through a riverbed.

What You'll Learn
Where to pan for garnets
While garnets can be found in many areas due to their widespread nature, there are several notable locations for panning garnets. One of two places in the world where star garnets can be found is Idaho. These gemstones are typically burgundy to black and are cut into rounded shapes. The other notable site is in North Carolina, specifically Cowee Valley, which produces rhodolite garnets ranging from soft pink to deep purple-red. Southern California, near San Diego, is another location for orange spessartine garnets.
Montana, known as the "Treasure State," is also a popular destination for garnet panning. Sites like Gem Mountain Mine and Red Rock Mine offer opportunities to prospect for sapphires and garnets. The Ruby River and its tributaries in the Greenhorn Mountains are responsible for bringing garnets downstream. Additionally, River of Gold on the outskirts of Virginia City offers gold panning and garnet mining, providing a glimpse into the state's rich mining history.
Connecticut is another state where garnets can be found. In Woodstock, Connecticut, a small meandering brook yielded pink garnets, though they were initially mistaken for rose quartz due to their colour and size.
When it comes to panning for garnets, it's important to remember that they are often found in areas associated with gold. Pyrope garnets, in particular, are commonly discovered alongside gold in streams and creeks. So, if you live near an area known for gold or garnets, you may have a good chance of finding garnets in local streams.

How to identify garnets
Although identifying individual varieties of garnet is not important for non-specialists, there are several ways to distinguish a real garnet from a fake one. Firstly, garnets are usually easy to identify by their hardness, crystal habit, and occurrence in metamorphic rock. They typically occur in their crystal form as rounded dodecahedrons (twelve-sided) or twenty-four-sided trapezohedrons. Genuine garnets exhibit rich colours, ranging from deep red to vibrant greens, and possess a notable hardness. On the Mohs scale, this gemstone scores 6.5 to 7.5, making it resistant to scratches from substances with a lower rating, like copper or glass.
Garnets are also known for their dense, saturated hues. If your stone is lighter, brighter, or more vivid, then it may be a fake. Synthetic garnets may exhibit flawless clarity or unnatural perfection that real garnets rarely show. Genuine garnets contain rich colours and inclusions, whereas synthetic garnets may have overly saturated and consistent coloration that doesn't vary. The gem's brilliance is one of its main USPs and is responsible for its growing demand worldwide.
You can also distinguish a real garnet from a fake by holding the stone close to your eye and looking through it at a distant light source. You should be able to see the light being reflected off the inner walls of the stone. Then, tip the stone on its axis and look through it again. This time, the reflection should be visible in a rainbow pattern. If you are unable to see the reflections in your stone, it is likely an imitation.
Another way to identify a real garnet is to use a magnifying glass or a microscope to closely examine the garnet for imperfections. While synthetic gems can also have flaws, the nature and distribution of flaws within a real garnet can help determine its authenticity. Look for unique inclusions or irregularities that are commonly found in natural stones.

What colour are garnets?
Although garnets are typically known as dark red gemstones, they actually come in a wide variety of colours, including orange, brown, yellow, pink, green, blue, and even colourless. The different colours of garnets are caused by the presence of different chemical elements. For example, the presence of iron or manganese can cause the stone to appear red, while cobalt can cause the stone to appear green. The name "garnet" comes from the Latin word "Garanatus", which means "seedlike", as the stones resemble pomegranate seeds.
The most common colour of garnet is red, with the pyrope and almandine varieties from Europe typically exhibiting this colour. However, there are also many other types of red garnets, such as rhodolite, which can vary from soft pink to deep purple-red, and the vivid red "ant hill" garnets from Arizona, which are known to be redder than most rubies.
Garnets can also be found in a range of orange hues, from the reddish-brown spessartite garnets, which resemble the colour of cinnamon, to the orange spessartine garnets found in Southern California near San Diego. The hessonite variety of grossular garnet also often has a orange colour with unique toffee-coloured streaks.
Green garnets are also relatively common, with the Tsavorite variety being found in Tanzania and Kenya, and the Demantoid variety originating from Russia and more recently Madagascar. The Merelani Mint garnets, a by-product of tanzanite mining, are a beautiful lighter green with occasional minty blue colours.
Although less common, garnets can also be found in a variety of other colours, including blue, violet, and even colourless. The new material from Mozambique is said to be quite purple, while the stones from Mahenge in Tanzania exhibit peach and light pink colours.

What is the value of garnets?
Garnets are typically known as red gemstones, but they actually come in a wide variety of colours, including green, pink, purple-red, and even colour-changing varieties. They are one of the oldest known gemstones and have been used since antiquity for their beauty and hardness. The variable chemical composition of garnets makes them unique, as they are always a silicate (SiO₄) with two other elements.
The value of garnets depends on their type and variety. Almandines are the most common type of garnet and come in a wide range of colours. The blend of almandine-pyrope creates the dark red variety often associated with traditional garnet jewellery. Grossular garnets, on the other hand, rarely appear red or dark in tone but can be found in almost every other colour, including green, orange, and even colourless specimens. Their light to medium tones and vibrant colours make them excellent jewellery stones.
Andradites are among the rarest garnets and feature the highest dispersion of all garnet varieties, even exceeding that of diamonds. Demantoids, a green garnet variety of andradite, are especially prized by collectors and command premium prices. Tsavorites, with their emerald-like green colour, can also fetch high prices, while Hessonite "cinnamon stones" are more affordable yet still popular.
The location of the garnet deposit can also affect its value. For example, Idaho is one of the two places in the world where star garnets can be found, and these gemstones are highly valued for their unique colour and asterism. Similarly, Cowee Valley in North Carolina produces rhodolite garnets, which range from soft pink to deep purple-red in colour. While the United States has some varieties of grossular garnets, it does not have deposits of the highly valuable tsavorite garnets, which are found in other parts of the world.

How to cut garnets
Cutting garnets can be challenging, but the process is quite similar whether you're working with natural or lab-created garnets. Lab-created garnets are usually free from flaws and inclusions, so the process is often more straightforward.
Firstly, the cutter will select the best garnet and remove any flaws or blemishes with a gem saw. They will then choose a shape that maintains as much carat weight as possible while achieving the best cut quality. The garnet will be cut into a rough shape, and affixed to a dop stick with wax to make it easier to cut and shape. The dop stick is heated to create a good bond between the wax, dop stick, and gemstone.
The garnet is then cut to the desired shape, with the cutter working on the bottom of the stone first before completing the top. A slower cutting process with a finer grit lap will allow the cutter more control over the speed of cutting. Once the desired shape is achieved, the garnet is removed from the dop stick and polished.
The cutter will then cut a table into the garnet, using a 45-degree adapter dop to create a flat table. The angle is then changed to cut the main crown facets. The angle must be adapted for the ends of an oval shape to establish a level girdle. The cutter will then add star facets and polish the crown with a copper or ceramic lap to achieve perfect meets. The final step is to polish the table of the garnet.
Popular garnet cuts include the Asscher, emerald, baguette, round, oval, and cushion. The Asscher is a square with cut-off corners, and if elongated, it becomes an emerald cut. The baguette is similar to an emerald cut but with angular, not bevelled, corners. The round and oval cuts are popular for rings, as they make the finger look slender and sleek.
