Most human eyes have viewed the mystical magnificence of quartz, maybe without the need of understanding it is the most frequent mineral on Earth, but which is the rarest?
Minerals are scattered all over the place on our world, from glittering flecks in gravel or sand to true concealed gems. In accordance to the U.S. Geological Culture (opens in new tab), minerals are the natural way taking place things or compounds that are inorganic, indicating they do not have carbon. Every variety of mineral displays order in its inside structure and has a distinctive chemical make-up. The form a mineral’s crystals just take, as properly as its other physical homes, can vary.
The rarest mineral on Earth is kyawthuite. Only one crystal, found in the Mogok area of Myanmar, is regarded to exist. Caltech’s mineral database (opens in new tab) describes it as a modest (1.61-karat) deep orange gemstone that the Intercontinental Mineralogical Affiliation (opens in new tab) formally recognized in 2015.
Even so, minor is identified about kyawthuite, so let’s move on to the second-rarest mineral in existence. This is painite, which appears as deep crimson hexagonal crystals (though there are some pinkish exceptions). Nevertheless painite is now extra effortlessly found than it used to be, this mineral is however rare, and its chemical composition makes it something of a scientific enigma.

In 1952, the English gem collector and dealer Arthur Discomfort acquired two crimson crystals in Myanmar, according to George Rossman (opens in new tab), a professor of mineralogy at CalTech, who has been investigating painite considering the fact that the 1980s and maintains an extensive databases (opens in new tab) of all the samples he has analyzed microscopically.
Agony thought the crystals were being rubies, which the region is famed for, but unbeknownst to him they have been really a thing much rarer.
Painite (which took on Arthur’s surname) is occasionally unearthed alongside with rubies and other gemstones. That clarifies why Pain assumed the crystals ended up rubies when, in accordance to Rossman, he donated them to the British Museum in 1954 for even more analyze. Another painite sample from Myanmar surfaced in 1979, and right up until 2001, people three crystals had been the only regarded specimens of painite in the environment.
The extremely very first painite crystal uncovered, identified as painite #1, was later on analyzed by Rossman. His latest painite study was published in Mineralogical Journal (opens in new tab) in 2018.
“I carried out [studies] of the [first] sample,” he instructed Are living Science. “[My results] turned the specifications by which even more discoveries of painite ended up confirmed.”
It was by way of this investigation that Rossman decided which elements make up painite. With infrared spectroscopy, infrared radiation is utilized to discover components based mostly on how they absorb, replicate and emit that light. With Raman spectroscopy, a laser is employed to scatter obvious, infrared or ultraviolet light, which tends to make the molecules give off one of a kind vibrations that make them identifiable.
Rossman also uncovered there was an mistake in the chemical makeup at first decided by experts at the British Museum. Although they experienced appropriately identified aluminum, boron, calcium and oxygen, the component zirconium was missing. An additional matter Rossman observed out was what gave painite its reddish hue It has trace amounts of vanadium and chromium that could possibly make it deceptively surface like a ruby.
But what can make painite so uncommon? For one, it is only located in Myanmar, but the true reason lies in its development. Painite is a borate crystal, meaning it consists of boron. It also includes zirconium. Boron has a notoriously complicated time bonding with zirconium. In reality, painite is the only mineral in which the two have been located bonded in mother nature. Even though the motive is even now unclear, zirconium and boron have not been uncovered jointly in sizeable concentrations, as Rossman explained. It is also considered that these things may possibly not be pretty steady jointly in contrast with other components they could bond with.
“To my information, no a person has done a severe study of what it takes to kind painite,” Rossman said. “I know of no attempt to synthesize it in a lab.”

Why Myanmar?
What Rossman does have an notion of is why painite and so a lot of other gems, these types of as kyawthuite, are located in Myanmar. When the historic supercontinent of Gondwana commenced to split about 180 million many years back, India crept north and collided with what is now South Asia. Stress and warmth from the collision formed a treasure trove of rocks, several of them gemstones. He thinks the boron in painite and other borate minerals possibly came from shallow seas about the newly formed land mass.
Rossman has had several crystals suspected to be painite despatched to him for identification. Some have been concealed in plain sight for many years, as they have been often stashed in baggage of rough gemstones or in the palms of sellers and collectors who misidentified them.
Painite ideal for luxe jewellery is tricky to come by and valued as significant as $60,000 a carat, Rossman explained. What determines the value can be subjective, but the less flaws, the better.
It should be pointed out that there are ethical concerns about mining in Myanmar, also renowned for other gemstones and specimens of very small prehistoric creatures trapped in amber. Human Rights Enjoy (opens in new tab) raises awareness about human legal rights abuses from the military govt, which earnings from the mining industry, which has unsafe and sickness-infested mines, pressured labor and youngster labor. Some jewellery providers refuse to obtain gems mined there for this rationale and some experts decrease to study specimens (opens in new tab) from this nation.
Painite is now extra common than it as soon as was. Several crystals commenced to show up in 2005, all within just that 12 months, and most painites can now be uncovered in Myanmar’s Wet Bathroom and Therein Taung regions.
Although painite no for a longer period wears the crown of rarest mineral, it is really however a genuine gem.
