Think you know everything about gemstones? Did you know the top 10 rarest gemstones in the world? Anyway, let's find out in this article! Gemstones are not mere stones; they are geological marvels that have great significance historically and culturally. Due to their scarcity, color differences, and the process through which they are formed, they are amazing and valuable objects.
Gemstones have been valued and coveted since the ages of antiquity to the present generation; some signify wealth, love, and magical powers. Some of the rarest gemstones are Diamond, Ruby, Emerald, Sapphire, Alexandrine, and Tourmaline, among others.
Gems are minerals and have undergone the process of cutting and polishing for the purpose of using them in ornaments and various other aspects. They are formed under certain geological occurrences, such as when rocks are exposed to high temperatures and pressure. The process may occur over millions of years, and the gemstone formation is enabled in locations such as volcanic rocks, pegmatites, or hydrothermal veins
Did You Know?
There are around 200 types of Gemstones that We know of till now!
What is the rarest gemstone? Well, None! Yes, you heard (read) it right. Large stones that do not have inclusions (internal characteristics of a gemstone that can be seen with the help of a loupe) are considered to be rarer and, therefore, more valuable.
Before science, here’s some maths! Around 60% of the value of gemstone is determined by its color. The color of gemstones is mainly attributed to the incorporation of trace elements in the gemstones and the structure of the crystal lattice. The element chromium imparts red to rubies and green to emeralds, while iron with titanium yields the blue color in sapphires.
The mineral Manganese imparts pink colors to tourmaline. Alexandrite also undergoes a change of color because it experiences an exceptional method of light absorption, which makes the stone truly extraordinary and the rarest gem in the world.
The history and mythology of gemstones have placed a significant amount of value on these stones for their aesthetic qualities and other plausible advantages.
Various cultures valued the power of gemstones, including one amulet made from a particular gemstone, which is believed to have the ability to ward off evil spirits. Gemstones have also had meanings of status and affluence, used by regents and nobility.

The wait is over! Here are the most popular and rarest gemstones in the world:
While usually associated with imperial jade green, jadeite mines also contain lavender, yellow, orange-red, blue, black, and colorless varieties. Mayan and Chinese civilizations valued jadeite and renowned it with fascinating legends.
Its value depends on translucence and texture, with top-quality material appearing full of water or like a drop of colored oil. Pricing is highly subjective. There's a Chinese saying: ”Gold has value; jade is priceless.”
One of the rarest gemstones, Musgravite, found in 1967 at Musgrave Ranges in Australia, is an aluminum oxide mineral containing magnesium iron zinc in varying amounts. It can be green, blue, or purple; it is very rare and hard, and it belongs to the same group as taaffeite.
Other deposits are located in Tanzania, Greenland, Madagascar, and Antarctica. Due to its rarity, Musgravite is a highly sought-after gemstone with an average price of $6000 per carat.
Alexandrite was first found in 1830 in the Urals, Russia, and the gemstone is unique because it can change colors depending on the light’s intensity. Because of the presence of tiny amounts of chromium, it fluoresces emerald green to peacock blue by daylight while it shines ruby red to purple under incandescent light.
This color-changing ability made this rare gem very popular among the Russian nobility. This stone was named after Czar Alexander. It has been found more recently in Brazil and other places. Alexandrite is actually a June birthstone and is nowadays mined and, at the same time, produced synthetically for use in jewelry.
In general, black opal is one of the rarest and most demanded types of opal and is mainly extracted in Lightning Ridge, New South Wales, Australia. It is recognized by its body tone, which sets it apart from other kinds of opals; black opals have a darker appearance. They are very scarce, and their prices range from $3,500 per carat and above.
Paraíba tourmaline was first found in the 1980s in the Brazilian state of Paraíba. The intensity of the blue-green color of Paraíba tourmaline amazed the world of gems.
The price for these gems per carat was relatively high and steadily increasing over the years. While there are similar tourmalines found in Mozambique and Nigeria, Paraíba tourmaline still ranks among the most unique and expensive gems in the world.
Red beryl is another gemstone from the beryl family, and it is closely related to emerald, aquamarine, and morganite; it has a red color due to the presence of Manganese.
It was found in the Wah Wah Mountains of Utah in 1904, where it is estimated that just 5% of the excavated stones are gems. Because of its rich red-to-raspberry-red hue and scarcity, high-quality red beryl is the rarest gemstone and sells for between $10,000 and $15,000 per carat.
Benitoite is often similar to the diamond in terms of its scarcity and ‘fire,’ though it can be sapphire-blue as well, which is quite valuable. Gem-quality benitoite is found only in San Benito County in the state of California.
The available shades include a deep, rich blue with low visibility regarding dispersion and a medium shade with fire components.
Originally found cut and polished in Dublin, Ireland, in 1945, the taaffeite was first identified as a spinel. It is characterized by double refraction and is mined from alluvial gravels in Sri Lanka and Tanzania. Due to its scarcity, high-grade taaffeite is highly desirable and may cost about $35,000 per carat.
Diamonds are famous gemstones that possess a pink color, and they are very scarce and have a special charm. The color of their specific kind is normally attributed to EDS-specific plastic distortions during formation. They vary from flawless to included and have been recovered in different parts of the world, but about 80% of the total was mined in Australia’s now-closed Argyle diamond mine. These diamonds are highly polished and very rare in the market.
Painite mineral was found in Myanmar in the year 1951 and for many years, it was esteemed to be the rarest mineral. Prior to the 1980s, there were only two specimens recorded.
Despite these discoveries, it is estimated that only a thousand of these pieces have been found, and many of these are not suitable for carving. Painite is known for its red-brownish color and elevated demand; the highest-quality stones may cost up to $60,000 per carat.
