Rare and Beautiful: The Most Valuable Gemstones
In the world of gemstones, rarity and beauty often go hand in hand. Here, we explore some of the most valuable gemstones, each with its unique origins, properties, and qualities.
Tanzanite
Hailing from a tiny 4km strip near Mount Kilimanjaro in Tanzania, Tanzanite is exceptionally rare. Formed due to tectonic plate movements that fused mineral-rich magma in the Great Rift Valley region, this trichroic gemstone shows blue, purple, and red hues due to vanadium and chromium impurities. Tanzanite is about 1,000 times rarer than diamonds and valued for its rarity, unique coloration, and limited geographic source [1][3].
Mali Garnet
Discovered on the border of Mali and Burkina Faso, Mali garnet is a relatively new find in the gem world. Made up of a mix of grossular and andradite garnets, it displays a range of colors from fiery orange to green and even rare color-change varieties shifting from blue-green to purple-pink. Mali garnet has a hardness of 7 and is prized for its brilliance (high refractive index), color variety, and rarity due to small-scale manual mining [2].
Cat's Eye
Valued for their unique optical effect called chatoyancy, Cat's Eye gemstones feature a luminous band resembling a cat’s eye on the surface as the stone is moved. They are popular in jewelry and are believed to have astrological significance [4].
Lapis Lazuli
A deep-blue metamorphic rock, Lapis Lazuli has been prized historically for its intense color, often with pyrite inclusions that resemble gold flecks. While less rare compared to tanzanite or Mali garnet, it has been used in jewelry and as pigment since antiquity [4].
Peridot
Formed deep in the Earth's mantle and brought to the surface by volcanic activity, Peridot has a distinctive yellow-green color due to iron content. While beautiful and used in many jewelry pieces, it is more common and less valuable than tanzanite or Mali garnet [4].
Rose Quartz
Known for its gentle pink hues, caused by trace amounts of titanium, iron, or manganese, Rose Quartz is abundant worldwide and widely used in jewelry and ornamental objects but is neither rare nor highly valuable compared to the others.
Other notable gemstones include Emeralds, a green variety of the mineral beryl, getting their color from traces of chromium and vanadium [5]. Aquamarine, a blue-green variety of beryl, is often heat-treated to remove greenish tones [5].
Diamonds, the hardest gemstone on the Mohs scale, are made from pure carbon, and while colorless diamonds are the most popular, they can appear in many colors [6]. Garnets range in color from purplish red to reddish brown [7]. Topaz can appear in pale yellow, colorless, and pink shades [7].
Imperial topaz is the most highly valued, and Amethyst, a violet variety of mineral quartz, was once considered as valuable as ruby and emerald [8]. Opals show mixed colors through a phenomenon called "play-of-color," and Fire Opal from Mexico adds fiery orange tones [8].
Rubies are a form of corundum, known for their red color due to chromium, and Sapphires, a variety of corundum, can appear in blue due to titanium and iron [8]. Pearl, a purely organic gemstone formed in marine and freshwater mollusks, completes our list of valuable gemstones.
In summary, tanzanite and Mali garnet stand out for their rarity, limited origins, and striking colors, while Cat's Eye focuses on optical properties, and Lapis Lazuli, Peridot, and Rose Quartz are valued for their distinctive colors and historic or geological origins. Tanzanite’s extreme rarity and unique formation near Mount Kilimanjaro and Mali garnet’s diverse hues and recent discovery contribute to their high value [1][2][3][4].
