Top 15 Priciest Materials Found on Our Planet
1. Antimatter – The Costliest Substance at Over $62 Trillion per Gram
Antimatter is not just science fiction; it is one of the rarest and most expensive materials on Earth. Its extraordinary value of approximately $62.5 trillion per gram is primarily due to the immense difficulty in producing and storing it. Antimatter has the potential to revolutionize energy production, space travel, and even medical treatments, but its production remains a colossal challenge. Scientists at CERN and other institutions have managed to synthesize tiny quantities, but the costs are astronomical, making it a priceless commodity in theory — and a scientific marvel in practice.
2. Actinium-225 – An Rare Radioactive Metal Valued at $29 Billion per Gram
Used in targeted cancer therapies, Actinium-225 is an incredibly rare radioactive isotope. Its unique properties allow it to destroy cancer cells with minimal damage to surrounding tissue, making it a valuable asset in medical science. With an estimated value of $29 billion per gram, the scarcity of natural sources and complex synthesis processes make this material highly exclusive. Researchers are actively seeking more efficient sources and methods to produce this isotope to improve cancer treatment options.
3. Technetium-99 – The High-Value Radioisotope at $1.9 Billion per Gram
This radioactive isotope poses a crucial role in medical diagnostics, especially in nuclear medicine imaging. Though more accessible than many other rare elements, Technetium-99’s value derives from its applications in hospitals worldwide. Its production is complex, requiring nuclear reactors or particle accelerators, and its short half-life means it must be produced on-site in many cases. Its high value reflects both its importance and the difficulty in producing it.
4. Endohedral Fullerenes – Scientific Marvels Valued at $137 Million per Gram
These molecular structures are fullerenes encapsulating other atoms or molecules. Their unique quantum properties make them promising in medical applications, including drug delivery and advanced materials. The cost of producing high-purity endohedral fullerenes, at about $137 million per gram, reflects the intricate synthesis processes and the cutting-edge research scoped into these molecules.
5. Californium – A Radioactive Metal Fetching $27.8 Million per Gram
Californium, especially Californium-252, is a heavily radioactive element used in nuclear reactors, medical isotope production, and neutron sources for detecting explosives. Its short half-life and intense radioactivity make extraction and purification incredibly complex, driving its price to nearly $28 million per gram.
6. Red Diamonds – Luxurious and Rare, Valued at $5 Million per Gram
While diamonds are generally associated with jewelry, red diamonds are among the rarest, with only a few known to exist. Their vivid coloration and rarity drive prices as high as $5 million per gram. Some of the most famous red diamonds include the Moussaieff Red, valued for their unique hue and exceptional scarcity.
7. Painite – The Elusive Gem at $300,000 per Gram
Once considered the rarest mineral on Earth, Painite is a gemstone with a distinctive brownish-red hue. Its scarcity makes it highly valuable, with prices reaching up to $300,000 per gram. The mineral’s rarity lies in its geological formation, and only a handful of specimens are known to exist.
8. Diamonds – The Classic Luxury Commodity at $134,000 per Gram
While some diamonds fetch millions of dollars for jewelry, their price per gram averages around $134K for high-quality specimens. Diamond prices depend on clarity, color, cut, and carat weight, making them a stable investment and symbol of wealth across the globe.
9. Grandidierite – An Exotic Blue Green Mineral at $129K per Gram
Discovered in Madagascar, Grandidierite is an incredibly rare mineral prized for its gorgeous blue-green color. Its scarcity and unique optical properties drive its high price, appealing to collectors and gemstone connoisseurs.
10. Serendibite – A Rare Gem at $90K per Gram
Native to Sri Lanka, Serendibite is one of the rarest gemstones, primarily due to its limited deposits. Its striking violet-blue hue and rarity make it a highly sought-after collector’s item, commanding a steep price.
11. Red Beryl – The Scarlet Wonder at $50K per Gram
Often called a “berry,” red beryl is exceedingly rare. Found mainly in Utah, its vibrant crimson color combined with scarcity drives prices up to $50,000 per gram. It’s a prized gemstone among collectors seeking unique and rare minerals.
12. Benitoite – The Blue Heart of California at $42K per Gram
This gemstone, exclusive to California’s Benitoite Valley, is renowned for its intense blue color and rarity. Its official state gem status, paired with its limited deposits, boosts its value among collectors and jewelers.
13. Tritium – The Scientific Jewel at $30K per Gram
Tritium, a radioactive isotope of hydrogen, is used in luminous signs, watch dials, and nuclear research. Its high cost is due to complex production techniques and strict safety measures necessary for handling it safely.
14. Taaffeite – The Rarity Among Gems at $12,500 per Gram
Discovered by gemologist Richard Taaffe, this lavender gemstone is vastly rare. Its scarcity and unique color make it one of the most sought-after and expensive gems in the jewelry world.
15. Plutonium – Security and Science at $4,000 per Gram
A radioactive actinide element, plutonium is critical for nuclear weapons and reactors. Its high toxicity and strategic importance keep its markets tightly controlled, with prices around $4,000 per gram.
Note: These valuations are estimates based on current market data and scientific reports as of 2025. Keep in mind that scarcity, scientific applications, and market dynamics continually influence these prices.
