Pearls are among the few gems created by a living animal. Oysters and mussels build them layer by layer over years, and that unusual origin is a big part of why so many cultures have woven stories around them. Chinese legend links pearls with dragons, and Roman writers described them as one of the great…
For years, I assumed tanzanite was just another pretty blue stone. December’s birthstone, expensive, rare — but nothing particularly special beyond its color and price tag. Then I started learning about its story. It was discovered only in 1967 — within my parents’ lifetime. It’s found in exactly one place on Earth, a tiny patch…
Many people assume zircon is a cheap diamond imitation because its name sounds like cubic zirconia. It is not. Zircon is a natural gemstone, a zirconium silicate mineral, and it is one of the oldest minerals on Earth: tiny zircon crystals from the Jack Hills of Western Australia have been dated to about 4.4 billion…
For years, I thought diamonds were just sparkly stones that cost a lot of money. Engagement rings, April birthdays, expensive — but nothing particularly special beyond their price tag and marketing. Then I started learning about their history. The ancient Hindus placed diamonds in the eyes of statues, believing they were created when lightning struck…
For years, I thought turquoise was just a colorful stone you saw in Southwestern jewelry. Pretty enough, affordable — but nothing particularly special beyond its distinctive color. Then I started learning about its history. The ancient Egyptians called it mefkat — a word that also meant “joy” and “delight”. The Persians considered it the national…
For years, I thought opal was just a pretty stone that flashed colors. Nice to look at, affordable — nothing particularly special. Then I started learning about its history. The ancient Romans prized it above almost every other gem. The ancient Greeks believed it could grant prophecy and divine insight. A 19th-century novel unfairly cursed…
Alexandrite is famous for a trick no other major gem performs so dramatically: it looks emerald green in daylight and ruby red under incandescent light. The same stone, different light — which is exactly why people have made it a symbol of change. This guide keeps three things apart: gemological facts (what alexandrite is and…
I have a confession that still surprises people who know I write about gemstones. For years, I thought topaz was just that affordable blue stone you see in mall jewelry stores. Sky blue, Swiss blue, London blue — pretty enough, but nothing particularly special. Then I started learning about its history. The ancient Egyptians called…
Ruby is July’s birthstone, and its story is far richer than its color. In Sanskrit tradition (see our guide to the symbolism of ruby in ancient India) it was called ratnaraj — the “King of Gems.” According to legend, Burmese warriors embedded rubies under their skin hoping to become invincible. Medieval Europeans wore rubies in…
Sapphire is September’s birthstone, and it is far more than just a blue stone. According to a popular Persian legend, the earth rested on a giant sapphire that reflected its blue onto the sky. Medieval clergy wore sapphire rings as symbols of heaven. And today, it’s the stone of wisdom, loyalty, and truth — a…
