Beryl, a celebrated and ancient gem species counts emerald, aquamarine and the delicate pinky-peach morganite in its lineup. There’s also the elusive red bixbite, the priciest one, and an extremely rare jewel to boot. But one captivating variety hasn’t been around for eons. Early in the 20th century, German miners in Namibia digging for aquamarine happened upon a rich beryl pocket that exposed stunning saturated golden crystals. Previously unknown, they’d discovered yellow beryl. After the initial unearthing, yellow beryl deposits found elsewhere produced crystals in warm orange-ish shades or with a slightly greenish back color that would expand the new gemstone cache.
