Top 10 rarest gemstones in the world

Gemstones are more than ornaments — they are the Earth’s hidden secrets, crystallised over millions of years. While diamonds, emeralds and rubies are celebrated worldwide, there exists another category of stones so rare that even the wealthiest collectors may never encounter them. These are the gems whispered about in auctions, sought after by museums, and treasured by a select few.

Here are the top 10 rarest gemstones in the world, ranked by their scarcity, beauty, and allure.

1. Painite – The Rarest Gemstone in the World

Painite, discovered in Myanmar in the 1950s, once held the Guinness World Record as the rarest mineral on Earth. For decades, only a handful of crystals were known. Even today, facetable specimens remain almost mythical. Its reddish-brown hues may not seem dazzling, but rarity alone has transformed Painite into a legendary collector’s prize.

2. Gold Sheen Sapphire – The Second Rarest Gemstone

In 2008, Tanzim Khan Malik discovered the Gold Sheen Sapphire in Africa, and it instantly claimed its place among the rarest gems ever found. Its golden shimmer, glowing beneath deep sapphire tones, is a phenomenon seen in just 0.0001 per cent of sapphires worldwide.

Elite collectors in Japan, the U.S., and Europe wait years for access, with high-quality stones selling for $6,000 to $25,000 per carat and more. Its scarcity is such that even with money, buyers cannot simply acquire it. This exclusivity, combined with its unmatched beauty, makes the Gold Sheen Sapphire the world’s second rarest gemstone.

3. Red Beryl – The Third Rarest Gemstone

Also known as “Red Emerald,” Red Beryl is found only in Utah’s Wah Wah Mountains. It is said to be over 1,000 times rarer than diamonds, making it the third rarest gem in existence. Its crimson brilliance is caused by trace amounts of manganese, but most crystals are too tiny to cut. When a facetable specimen does appear, it can command over $10,000 per carat.

4. Musgravite – The Fourth Rarest Gemstone

Discovered in 1967 in Australia’s Musgrave Ranges, Musgravite belongs to the Taaffeite family but is significantly rarer. For years, fewer than 10 specimens were confirmed worldwide. Today, even as more stones have surfaced, its availability remains extraordinarily limited. Collectors may pay $35,000 per carat or more for fine-quality Musgravite, securing its rank as the fourth rarest gemstone.

5. Alexandrite – The Fifth Rarest Gemstone

Named after Tsar Alexander II of Russia, Alexandrite is famed for its dramatic color change: emerald green in daylight and ruby red under incandescent light. This “gem of two worlds” is considered the fifth rarest gemstone. Russian Ural deposits produced the finest specimens, but they are now nearly exhausted, making high-quality Alexandrite increasingly valuable.

6. Jeremejevite – The Sixth Rarest Gemstone

First discovered in Siberia, Jeremejevite later appeared in Namibia in pale blue to colorless hues. Its transparent clarity and limited supply rank it as the sixth rarest gemstone. Collectors prize facetable stones, though they are nearly impossible to find in large sizes, with prices reaching $2,000 to $3,000 per carat.

7. Grandidierite – The Seventh Rarest Gemstone

Discovered in Madagascar, Grandidierite shines with a unique teal-blue hue that gemologists describe as otherworldly. Transparent stones are almost never encountered, ensuring its place as the seventh rarest gemstone. When available, even small faceted pieces are treasured by collectors and museums alike.

8. Taaffeite – The Eighth Rarest Gemstone

In 1945, gemologist Richard Taaffe identified Taaffeite by accident after purchasing what he thought was a spinel. The stone turned out to be entirely new — the only gem first discovered in cut form. Its delicate lilac to mauve shades, combined with its extreme scarcity, make it the eighth rarest gemstone in the world. Only a few thousand specimens are known.

9. Benitoite – The Ninth Rarest Gemstone

Benitoite, discovered in San Benito County, California, dazzles with sapphire-like blues and fiery brilliance under UV light. Named the state gem of California, it is now nearly impossible to source since deposits are largely depleted. Collectors cherish it not only for its beauty but for its geological significance, ranking it the ninth rarest gemstone.

10. Black Opal – The Tenth Rarest Gemstone

The crown jewel of the opal family, Black Opal, comes almost exclusively from Lightning Ridge, Australia. Its dark body tone provides a dramatic backdrop for flashes of red, green, and violet that appear like galaxies in motion. Exceptional stones can sell for hundreds of thousands of dollars, but supply is extremely limited. This makes it the tenth rarest gemstone on Earth.

Closing Reflection

True luxury is never about abundance — it is about rarity and exclusivity. From Painite, the rarest of all, to the elusive Gold Sheen Sapphire, these gems remind us that some treasures cannot be acquired by wealth alone. They are fragments of Earth’s timeless artistry, found only in remote corners of the world, destined for the hands of a fortunate few.
