Though perhaps not as currently stylish as Ruby, Jade, or Pearl, Amber has a colorful history (remember the notorious Forever Amber heroine?). Unfortunately, it does come with the "Amber Alert" connotation for modern parents (and their children).

As flower names become more unique, so can gem names move beyond Ruby and Pearl to names like Topaz, Sapphire, and Peridot. Amethyst, the purple birthstone for February, has never been in the Top 1000, but could have some appeal, joining similarly-hued Violet and Lilac, all of which make great <a href="https://nameberry.com//list/614/names-for-aquarius-babies">names for Aquarius babies</a> or <a href="https://list/630/70-lovely-names-for-february-babies">names for February babies</a>.
 In the M.M. Kaye children's novel The Ordinary Princess, the protagonist is Princess Amethyst Alexandra Augusta Araminta Adelaide Aurelia Anne of Phantasmorani — Amy for short — who has been given the "gift" of ordinariness.

Antimony is a lustrous grey metal. Beware though - antimony is very poisonous and harmful to the environment, so a bit of a harsh name to give to a child.

More unique than Cooper, and a favorite among pet parents. Copper was the loveable bloodhound from Disney's Fox and the Hound. Keep in mind that Copper is also slang for a policeman.

Flint is one of the new macho names on the rise today, part old-school tough guy, part rebel. You won't find a tougher, steelier-sounding name; it's part of a genre on the rise along with cousins Slate, Stone and Steel. 
 Flint found itself on the popularity list for a few years in 1959-60, but would prove a distinctive choice today.
 Flint has superhero overtones--there's one in "Spiderman"--aka Sandman--and Captain Flint was a Marvel comic, and Flint is both a legendary pirate and a parrot in Robert Louis Stevenson's Treasure Island. But on the softer side, there's also inventor Flint Lockwood in Cloudy With a Chance of Meatballs.

Galena is the feminine of the Galen, which means calm. Galena is also a mineral-related name, a type of lead.

Galena

One of the jewel names in use a hundred years ago, for both boys and girls, due for revival along with sisters Ruby and Pearl. But interestingly, Garnet means pomegranate, the fruit who shares a deep red color with the jewel.

As a precious stone, Jade is known for its cool green hues, its importance in Chinese art, and its ability to transmit wisdom, confidence, and clarity. As a name however, Jade is a 90’s throwback in the UK, a Number 1 choice in France, and a returning gem in the US right now. 
Deriving from the Spanish phrase Piedra de la ijada, the name Jade means “stone of the side” or “stone of the flank” as it was once believed that jade could cure renal colic. While this might not be the most glamorous of meanings, it does give the name some extra history. 
Jade has been used to make carvings since Neolithic times, but as a given name, it only took off in the 1970’s, when Mick and Bianca Jagger chose it for their daughter. 
Originally used as a unisex name, the number of girls called Jade soon outweighed the number of boys, and with the rise of Jaden, it hasn’t been (statistically) unisex since the early 2000’s. 
Trendier than vintage Pearl, but more grounded than Sapphire or Topaz, Jade fits in well with other popular choices. Both a word-name like Scarlett and a one syllable option like Maeve, Jade feels just as right next to an Audrey or a Claire as it does to a Reese or a Kinsley. 
A big favorite in France where it has ranked in the Top 10 since the mid-2000’s, Jade is also well-loved in Belgium, Quebec, the Netherlands, and Monaco. Ihe US, it has had a shakier history, rising and falling on the charts. Now though, it’s at its peak in the Top 100, and given to nearly 3000 babies every year. 
Notable Jades include singer Jade Thirlwall, originally from the group Little Mix; Jade Ewen of the Sugarbabes; Jade, one of the original Bratz Dolls.; and Jane Goody, a TV personality, often remembered for openly sharing her cervical cancer diagnosis, which led to more people being tested and treated sooner. 
If you love Jade, but want some more inspiration, you could consider the Italian variant, Giada. You might also like another <a href= “https://nameberry.com/list/414/jewel-baby-names”>gemstone name</a>, like Opal or Garnet, a <a href=“https://nameberry.com/blog/tiago-and-thibault-the-latest-french-name-trends”> French favorite</a>, like Romy, Ambre, Roxane or Zelie, or a throwback British choice, like Chelsea, Jodie, Demi, or Tia.

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.
 
Jasper has a lot going for it—it's been rocketing up the ranks in the US, after long being considered a posh and charming name in England. Distinctly masculine, Jasper represents a variety of quartz—one of the few gem <a href="https://nameberry.com/boys-names">names for boys</a>—and is the first name of the great modern artist Jasper Johns. Our only caveat: Jasper is a favorite of a lot of hip parents, and has gotten even more popular since its strong appearance in the Twilight books and movies.
 Jasper has considerable literary cred as well, appearing in works by Sir Walter Scott, James Fenimore Cooper, Thackeray, and Thomas Hardy--as well as Stephenie Meyer. 
 Casper/Caspar is the German version.

There aren't many gemstone names that are firmly masculine but Malachite is one of these. The gemstone is a rich green colour and is often used for decorative sculptures. The name is thought to derive from the name of the Mallow plant, the leaves of which resemble the patterns on the gemstone. The name is also similar to the Hebrew name Malachi.

Marble

This rarely used boys name is one of the few gem names for a boy. Obsidian is actually a type of volcanic glass, formed when lava cools very quickly. This ultra-cool name might spark a love of volcanoes and geology in a little boy.

Opal is on the verge of a repolishing, following other jewel names like Ruby and Pearl. A Top 100 name during the first two decades of the twentieth century, the opalescent Opal has a good chance of coming back as another O-initial option.
 The ancient Greeks believed that opals were formed from the tears of joy wept by Zeus when he defeated the titans, and that the opal bestowed prophetic powers; the Romans considered it a symbol of hope and good fortune. It was a favorite gem of Queen Victoria.
 Opal Pelis is a character in Theodore Dreiser's seminal 1925 novel An American Tragedy.
 And keeping with the O theme, Opal is the birthstone of October, making it an appropriate choice for a little girl born in that month.

Opal

Peridot is the gem of the month of August, a vibrant green mineral, said to be good for helping people put the past behind them, and an interesting, undiscovered jewel name. It was regarded in ancient times as the symbol of the sun.
 Peridots figure in the mythologies of several cultures, including the ancient Egyptian and Roman. They are highly valued in Hawaii, where it is believed that they are the tears of the volcano goddess Pele. 
 If you want a truly original gem name, you might consider this instead of Opal or Ruby.

This may be a bit quirky to make it as a name, especially in first place.  If you love it, you might try it in the middle.

Vibrant, sassy, and bubbly, Ruby is a vintage gem that hasn’t lost any of its sparkle. Currently popular in a number of English-speaking countries, Ruby is proof of the 100 Year Rule, trending again for the first time since its heyday in the 1910s. 
The name of a precious stone, Ruby was ultimately derived from the Latin ruber meaning “red”. Despite its sweet, shiny contemporary feel, Ruby has in fact been used as a given name since the 1500s, though it really took off in the Victorian era, alongside Pearl and Opal. 
Many cultures consider rubies to be the stone of kings, and the gem is surrounded by symbolism of wealth, power, life blood, success, and protection. It is also the birthstone for July, which could make it a discreet honor for a July-born relation or just right for a July-born baby. 
In the US, Ruby was a popular choice in the early 20th century, and it peaked at #22 in 1911. By the 1940s however, it was falling down the charts, and while it never left the Top 400, parents turned away from Ruby and to the likes of Judy, Crystal, Rebecca, and Robin instead. 
Then, in the mid-2000s, Ruby made big moves in the UK, leaping to #1 in 2007. Propelled upwards by the catchy song by The Kaiser Chiefs which was released the same year and influenced by celebs such as Tobey Maguire and Charlotte Church choosing it for their daughters, Ruby moved back into the US Top 100 in 2013. 
A truly musical name, Ruby has featured in hits by The Rolling Stones, Cat Stevens, and Kenny Rogers, while namesakes of the fictional and famous variety including Rue from “Euphoria”, Ruby from “Steven Universe”, and Ruby Rose of “Orange is the New Black”, have kept the name in the public eye. 
Given to more than 3000 babies in the US every year and continuing to climb the charts, Ruby is one of those <a href="https://nameberry.com/list/339/vintage-baby-names">vintage baby names</a> that feels totally modern and full of life. 
Love Ruby but want to beat the trends? You could try another vintage gem like Edith, Lula, Twila, Betsy, or Fern, or perhaps something with a similar sound, like Thisbe, Prue, Billie, or Rumi.

Rock and Mineral Names For Nature Lovers

You see, I love rocks. And I see it as a disappointment that we aren’t taking advantage of all the cool rock name possibilities. There are so many rocks, crystals, minerals, etc. that we need to start using as names. I’ve decided to bring it upon myself to bring to the table what we nature name lovers have been missing out on.
Are these all the rock names?
No, I’m not perfect.
However these are the ones that call to me, the ones that I look at and go  “someone needs to add this to a baby names list .”
And the best part? 
They’re rocks! Even if I list it as a girls name it can likely work for boys because rock names are pretty unisex
