Because of their obvious relationship to jewelry, many of these names are more commonly used for girls than boys, although there are a few that can cross gender lines.

Gems Commonly Used

These twinklers are the most popular gem names today:

Amber: A yellow to brownish-yellow translucent fossil resin, much prized for its somewhat mysterious qualities – rub two pieces of amber together and they become electrified and warm to the touch. A very feminine-sounding name that became popular in the 1970s and continues to be to this day. Jade: A hard ornamental stone, usually green or white, much prized in Asian countries. It’s currently somewhat popular as a name for girls; it’s also had limited use for boys. Jewel: Not a gem per se, but the noun used as a name. The popularity of the singer Jewel should spur wider use of this name. Mica: A thin, crystallized mineral, easily separated and translucent. It’s also a feminine Hebrew name formed from Michael, so it’s in broader use than you may think.

Precious but Rare

These little gems are either unusual choices or are still being polished.

Amethyst: This lovely purple gemstone takes its name from the Greek word amethystos, meaning “not drunk,” as the Greeks believed that wearing this gem would protect them from intoxication. It’s the birthstone for the month of February and a possible choice as a girl’s name for babies born then, but not in wide use. Beryl: A very hard, lustrous mineral, best known in its forms as emerald and aquamarine. It has had its run as a fashionable jewel name, but with its similarity to Meryl Streep, could gain in popularity among parents looking for an old-fashioned name. Coral: Not a gem or mineral at all, but a hard substance made up of the skeletons of sea animals. Used by the Victorians during their gem-based naming fashion period, but not much since then. Diamond: Brilliant and clear, it’s one of the hardest substances known to man. As the birthstone for April, it’s a possible choice for girls born during that month. The name is currently somewhat popular among African-American families. Flint: Flint is a kind of quartz best known for its ability to produce sparks when struck against another stone. It may be a good choice for parents looking for a tough-guy image for a little boy. Garnet: A deep red mineral that gets its name from the Latin granatus, which means “having seeds,” as small garnets look very much like the seeds of a pomegranate. It’s the gemstone for January. Turquoise: The sky-blue to green stone that’s widely found in the western U.S. Its name comes from a Middle English word for Turkey, as it is also found there and first came to England from that country. Jacinth: Not often seen, it’s a reddish-orange precious stone of the zircon family. Jacinda, a form of this name, is more often used. Jasper: An opaque, multi-colored quartz, often found in the western U.S. The name is thought to come from an ancient Persian word that means “lord of the treasure.” It’s not a bad name for a boy, but it might be too close to Casper (the friendly ghost) for some. Jett: A hard black mineral, currently fashionable in jewelry. John Travolta and Kelly Preston used this name for their son, but they probably weren’t inspired by this meaning. Onyx: A gray-to-black agate often used as a gemstone in men’s jewelry, it’s rarely used as a name today. Opal: Gemstone composed of glassy, translucent silicas that both reflect and refract light. It’s the gemstone for October and was once in fairly wide use, but sounds old-fashioned today. Pearl: The valuable growth formed by irritated oysters. This was another very popular gem name during the Victorian era. Ruby: A deep-red variety of the mineral corundum, rare today and much valued as a precious gem. Sapphire: Another form of the mineral corundum. In its blue form, sapphires are equally as rare as rubies. Topaz: A fairly common gemstone, it’s found in colors ranging from white to yellow to blue.

Not Even a Twinkle in Their Parent’s Eyes

These names have lost their luster, or never really had it.

Crystal: Clear, translucent quartz. A name with a New Age feel, thanks to the minerals that factor heavily in rites and rituals related to this movement. It also dates back to the early 1980s and the television show Dynasty, which makes it sound dated today. Emerald: One of the best-known forms of the mineral beryl. It’s not in common use. Galena: A gray mineral with a metallic luster that is the principal ore of lead, but it also often includes silver. Ivory: Another element that’s more animal than mineral, taken from the tusks of elephants. It’s use might be construed as politically incorrect because of the widespread slaughter of these animals.
