Indicolite has been around for centuries and, in fact, the Egyptians believed that the gem traveled over the rainbow, gathering its vast array of colors during its journey. Later, in the 18th century, Dutch scientists promoted the idea that feverish children could be put to sleep by wrapping the stone in silk and then placing it against their cheeks.

About the same time, the wealthy began to wear the gems in jewelry; it was believed to ward off evil, dispel curses and protect the wearer from danger. Later, it was discovered the stone contained an electrical charge.  Indicolite turns into a magnet, this occuring when it’s rubbed or heated in some way.
It wasn’t long after that when people began to believe the stone would attract love as well as light objects.

Properties of Blue Indicolite Tourmaline

One of its most interesting features of blue indicolite tourmaline is that its the only crystal mined that is perfectly triangular. The gem is found in long, slender prismatic and striated columnar-like tubes. Its formation happens because the crystals grow in a trigonometrical system. That allows it to change colors when viewed from different angles. The property is called pleochroism.

Indicolite is a crystal silicate mineral compound categorized as a cyclosilicate. It contains magnesium, iron, lithium, aluminum and/or potassium. Of the 14 types of tourmaline, blue is one of the rarest. Chemically, it is classified as an Elbaite with a chemical composition of Na(Li1.5Al1.5)Al6Si6O18(BO3)3(OH)4 and a 7-7.5 hardness on the Mohs scale.

Tourmaline is mined where pegmatite, granite and gneiss veins formed at a 45 degree angle deep in the earth. Miners look for dykes and, once discovered, follow the vein collecting gems along the way. It is an accessory mineral found in igneous and metamorphic rocks. During hydrothermal activity, the crystals form in cavities and fractures. Unfortunately, during the mining process, only a small percent of the rock contains the gems and only about 5% of the tourmaline collected is categorized as gem-grade.

Indicolite is allochromatic meaning it can come in a variety of colors. However, the light blue to bluish green indicolite is rarely found making it more expensive than other colors.

Indicolite gemstones are often used as the birthstone for October, adopted by the American National Association of Jewelers in 1912. Those that are larger than 1-2 carats are quite valuable, whereas those ranging 4-5 carats are extremely rare making them very expensive. The larger the stone, the darker it will be. The most common form is dark greenish-blue while the rarest is medium-dark blue in color.

Jewelry in all types and forms have been made from indicolite. The true blue form strongly resembles sapphire, which is why the price has been increasing in recent years. The biggest buyers are from Germany, Japan and Switzerland. The brightest of the blue indicolites resemble the London blue irradiated topaz. Many buyers are now seeing such a purchase as an investment and, most frequently, it is only found in one-of-a-kind jewelry. Because the colors are so hard to match from stone to stone, buyers can expect to pay 20-30% more for groupings.

How to Care for Your Indicolite

The blue tourmaline acquired its name from the Latin word for a blue-colored plant known as Indicum. The stones demand the highest prices of all gemstones in the tourmaline family due to their rarity. Due to its unusual properties, tourmaline will not scratch or break when worn. However, when cleaning, do not use an ultra-sonic cleaner or steam. It only takes a little soapy water and a small, soft brush to keep the colors and sparkle vibrant.
