Diamonds get called rare constantly, and fairly so, but there is a gemstone considerably harder to come by that most people have genuinely never heard of. Meet red beryl, sometimes called red emerald, a stone so scarce that one crystal turns up for roughly every 150,000 gem-quality diamonds found.
Discovered by accident in Utah

Red beryl was first identified in 1904 in Utah's Thomas Range by a miner named Maynard Bixby, which is where its original name, bixbite, came from. It belongs to the same mineral family as emerald and aquamarine, but owes its striking raspberry red colour to trace amounts of manganese rather than the chromium or iron responsible for other beryl colours.
Found in exactly one place on earth

Unlike almost any other commercial gemstone, red beryl has only ever been found in gem quality form in one location, the Wah Wah Mountains of Beaver County, Utah. No other country has produced crystals large or clear enough to be cut into facetable stones, which is a huge part of why this gem remains so staggeringly rare.
The numbers are genuinely wild

Most red beryl crystals come out under one carat, and the largest faceted stone ever recorded sits at only around eight carats. Given that scarcity, fine examples have sold for tens of thousands of dollars per carat, putting red beryl firmly among the most valuable gemstones in the world, despite most people never having heard its name.
Why it stays so under the radar

Part of the reason red beryl remains so unfamiliar comes down to supply. With such a tiny, single-source output, there simply isn't enough of the stone to build widespread demand or recognition the way diamonds, sapphires, or emeralds have over the decades. It has become something of a collector's secret rather than a mainstream choice.
Worth knowing if you love rare stones
If you are drawn to gemstones with a genuine story behind their rarity, red beryl is about as compelling as it gets: a single source, single country stone rarer than diamond, hiding in plain sight.
