What is Rhodolite?

Rhodolite is a mineral, a variety of the pyrope, which belongs to the garnet group of mineral gems. It ranges in color from purple or red to rose pink, and can be light or dark in shade. This reddish color is where rhodolite gets its name. The term rhodolite is derived from the Greek word rhodon, meaning “rose.” The name rhodolite, however, seems to be unrecognized as an official term.

Rhodolite is commonly used as a gemstone. This means that it may be used to make jewelry or for other decorative purposes. Rhodolite is considered a semi-precious gemstone. Rhodolite is found in North America, in the State of North Carolina. More specifically, rhodolite can be mined in the Cowee Valley, which lies in Macon County, North Carolina. Other mineral gems with similar pink color include rhodochrosite and rhodonite.

The mineral makeup of rhodolite is a combination of iron, magnesium, and aluminum silicate. These chemicals are common to the pyrope group. Rhodolite is, therefore, a type of garnet that exhibits the chemical properties characteristic to the pyrope group of garnets. Not all pyropes are transparent, and therefore not all can be used as gemstones. Furthermore, rhodolite, although it is considered part of the pyrope group, also exhibits a few qualities of the almandite group, and is therefore considered a composition of pyrope and almandite.

Pyropes, including rhodolite, usually originate in the ultramafic rocks in the Earth’s mantle. This means that the substance which eventually becomes a rose colored rhodolite started out as magma, which cooled or otherwise solidified into an ultramafic rock. Over time, this rock formed the mineral gem rhodolite due to specific chemical makeup, including qualities such as low amounts of silica and potassium, and high amounts of magnesium and iron.

Pyrope is one of six common species of garnets, each of which is distinguished on the basis of its chemical makeup. Almandine, spessartite, grossular, uvarovite, and andradite are the other five. These six common garnet species are further divided into two groups, the Pyralspite garnets, which include almandine, pyrope, and spessartine, and the Ugrandite garnets, which include andradite.

Rhodolite is a variety of pyrope garnet, which is a blend of pyrope and almandine garnet. It's known for its vibrant raspberry to rose-red hues, which are highly sought after in the gemstone market. Unlike other garnets, rhodolite typically has a lighter tone and lacks the brownish secondary colors found in many red garnets.

Rhodolite stands out from other garnets due to its unique color, which ranges from pink to purplish-red, and its exceptional transparency. It's less common than the typical red garnets and often comes without the muddy brownish or orange overtones. Rhodolite's color is attributed to its chemical composition, which includes a higher amount of magnesium than other garnets.

Rhodolite garnet is mined in several locations around the world, including Tanzania, Mozambique, Sri Lanka, Zimbabwe, and the United States, particularly in North Carolina. The gemstone's name is derived from the Greek word "rhodon," meaning rose, which reflects its pinkish hue. Each source can produce stones with distinct qualities and color variations.

The value of rhodolite garnet is primarily determined by its color, clarity, cut, and carat weight. The most prized rhodolites exhibit a vivid raspberry color, are free of visible inclusions, and are well-cut to maximize brilliance. Larger stones with these qualities are rarer and thus command higher prices in the gemstone market.

Yes, rhodolite is an excellent choice for jewelry due to its hardness, which ranges from 7 to 7.5 on the Mohs scale. This makes it durable enough for everyday wear. Its alluring color and brilliance make it a popular choice for rings, earrings, pendants, and other types of fine jewelry. Jewelers and consumers alike appreciate rhodolite for its beauty and versatility.

To maintain the beauty of rhodolite jewelry, clean it with warm soapy water and a soft brush. Avoid exposing the stone to harsh chemicals or extreme temperatures, which could damage it. It's also wise to store rhodolite jewelry separately to prevent scratches from harder gemstones. Regular professional check-ups are recommended to ensure the setting remains secure.
