About Diamond: April's Birthstone @GemologicalInstituteofAmerica

Uploaded April 2026 | Updated September 2026, 2 days ago

Natural diamonds began as carbon millions to billions of years ago and transformed under intense heat and pressure into the hardest natural mineral on Earth. Some emerge colorless. Others develop rare fancy hues like blue, pink or red due to trace elements or subtle changes in their crystal structure.

What is your favorite fancy color diamond?

$This is one of the rarest gems in the world... Red beryl is one of the rarest gemstones in the world. Like emerald and aquamarine, it belongs to the beryl mineral family, but its distinct red hue comes from traces of manganese within its crystal structure. Because of its rarity and distinctive color, red beryl has become highly prized among collectors and gem enthusiasts. Most gem-quality red beryl comes from a single region: the Wah Wah Mountains of Utah in the United States, where it forms in cavities within rhyolite volcanic rock. Because the crystals grow in small cavities, red beryl crystals are typically very small, and fine stones over one carat are extremely rare. Many crystals are heavily included or fractured, making clean, faceted stones especially valuable. Beyond its rarity, red beryl is fascinating to scientists because it forms in very unusual geological conditions, requiring both beryllium and manganese to occur together in volcanic environments—an uncommon combination in nature. Today, red beryl is regarded as a collector’s gemstone, prized for its rarity, its connection to American history and its striking color—making it one of the most extraordinary members of the beryl family.
