First, let’s clear the air. Diamonds are classic, sure, but they aren’t the priciest. A high-quality, one-carat diamond might set you back a few thousand bucks—cute, but chump change in the gem world. Rubies and emeralds can cost more, with fine Burmese rubies hitting over $1 million per carat. But even they aren’t the undisputed king.
The real heavy hitter? It’s a gem you’ve probably never held: painite. Yes, painite, discovered in Myanmar in the 1950s, was once the rarest mineral on Earth. For decades, only a handful of crystals existed. Today, it still commands prices above $50,000 per carat—and sometimes way more for a decent specimen.
But Wait—There’s a Twist
Here’s where it gets fun. The “most expensive” title depends on who you ask. Blue diamond is a fan favorite, with the famous 12.03-carat “Blue Moon” selling for over $48 million in 2015. That’s roughly $4 million per carat—yikes! For a deep, ocean-hued sparkle, blue diamonds are the undisputed champs of auction houses.
And then there’s jadeite, a type of jade that’s wildly popular in East Asia. A single bangle of top-quality imperial jadeite can fetch $30,000 or more. The finest jadeite from Myanmar has sold for over $1 million per carat in rare cases. It’s not a “stone” in the typical sense—it’s a symbol of status and luck.
