STUNNING MARQUISE FACETED GENUINE (NATURAL) IOLITE LOOSE STONE

Iolite is a mineral that belongs to the group of silicate minerals known as cyclosilicates. It has a chemical composition of Mg₂Al₄Si₅O₁₈ and forms in high-temperature, high-pressure environments such as metamorphic rocks. The color of iolite is caused by the presence of iron in its crystal lattice. The intensity of the color can vary depending on the amount of iron present and the angle from which the stone is viewed.

One of the most interesting features of iolite is its pleochroism. This property means that the stone appears to have different colors when viewed from different angles. For example, when viewed from one angle, iolite may appear blue, while from another angle it may appear violet. This characteristic has made iolite a popular gemstone for use in jewelry, as it can create unique and eye-catching effects in the stones.

Iolite is a relatively soft stone, with a hardness of 7-7.5 on the Mohs scale. It is not as hard as many other gemstones, such as diamonds or sapphires, and as a result, it may be prone to scratches and damage if not handled carefully. It is also sensitive to heat and can be damaged if exposed to high temperatures.

Despite its relative softness, iolite is a popular gemstone for use in jewelry due to its unique color and pleochroism. It is commonly used in rings, necklaces, and earrings, and can be found in a range of different cuts and settings.
