4 Of The Rarest Gemstones In The World

Diamonds may be expensive and eternal, but there are other rarer, far more unique gemstones that outrank it in terms of beauty and color, like tanzanite gemstones, for example. A gem may be classified as rare based on its size, color, location, or a number of other factors.

Grandidierite

Grandidierite may be complicated to pronounce, but it looks ethereal. The gemstone occurs naturally in many different colors, including blue, green, neon green, and even neon blue, which results from iron impurities in the crystalline structure. The largest grandidierite found weighs about 78 karats. Another interesting feature displayed by this gemstone is that it shows trichroic pleochroism - based on the angle you view the stone, it might appear a darkish blue/green, dark green, or even colorless.

Australian Opal

The Australian Opal has been around since 1875 and remains just as valuable as it ever was. The colors in these opals occur when spheres of silica oxide start forming. However, the temperature, chemical conditions and pH level required for this process to occur happen together very rarely. Apart from this, it seems that the mines are being depleted, making the precious stone even more so.

Jeremejevite

The gemstone is not just unique in name, but also in properties. A rare piezoelectric mineral, the jeremejevite gemstone generates electricity when put under immense mechanical stress. It was first discovered in Siberia in 1883. Since then, this extraordinary stone has been found in the mountains of Tajikistan and even in parts of Germany and Namibia. Due to the stone’s unique inclusions, such as feathers and growth lines, it is impossible to clean using traditional mechanical systems. The gemstone's large size and vivid color make it very rare.

Tanzanite

The Tanzanite gemstone belongs to the zoisite gemstone family and was discovered as recently as 1967. In gemstone years, this stone is quite young. This stunning gem is only found in Northern Tanzania, and nowhere else. The unique colors it displays makes it an instant eye-catcher. It displays a unique phenomenon, called trichroism. When you look at the tanzanite gemstone from different angles, it might appear a vivid blue, violet, or even red. This gemstone too is in limited supply and the mines in Tanzania might run out in the next 20-25 years.
