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).

Amber

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.

Amethyst

Dated British favorite that never caught on in this country, where Jade remains the green gem of choice. 
Interesting namesakes: British writer Beryl Bainbridge and British aviatrix Beryl Markham.

Beryl

Citrine is a type of quartz named after its citrus-colored hues. if Amethyst, Jasper, and Onyx (all other types of quartz) can be used, why not Citrine, which has a lovely French-sounding suffix. Citrine is one of the many rare and attractive <a href="https://nameberry.com/search/girls-names/c">girl names starting with C</a>.

Citrine

First used during the Victorian craze for jewel names; it could rise again, along with Ruby and Pearl, though it doesn't have as much luster. 

Coral

Peaking at #9 in 1982, Crystal's popularity in the 70s and 80s stems from its sparkling natural namesake and several notable bearers, like country music singer Crystal Gayle and Dynasty character Krystle Carrington. But it has since lost some of its luster for American parents, now ranking in the mid-600s. Ruby, Gemma and Pearl are fashionable alternatives, but nowadays Crystal could actually be a more unexpected choice for your little gem.

Crystal

Diamond sparkled all through the nineties--reaching as high as Number 150 in 1999. Although its shine has diminished quite a bit, it remains in use. 

Followers of the British royal family may know that the name was given in honor of Queen Victoria's sixtieth anniversary on the throne - her Diamond Jubilee. It's said that the queen asked that her granddaughter, born in 1897 during the jubilee year, be named Diamond. But Victoria's son, the future George V, chose Victoria Alexandra Alice Mary instead.

Emerald is the intriguing color and jewel name of the deep green stone treasured as far back as ancient Egypt — it's supposed to open one's heart to wisdom and to love and be good for strengthening relationships — which could make for an interesting, unusual name, particularly with the popularity of so many Em-starting names. 
 Emerald is the birthstone of May, making it extra appropriate for a girl born in that month. Some pleasant associations: the Emerald Isle and the Emerald City.
 Esmeralda is the Spanish version.

Gemma is a jewel of a name, an Italian classic that was very popular in 1980s England, but has only recently been started to be used here; it entered <a href="https://nameberry.com/popular-names">the list</a> in 2008.
 Coming from a medieval Italian nickname for a precious gem, Gemma was the name of Dante's wife and was borne by a nineteenth century saint.
 Gemma is the name of the character played by Katey Sagal on Sons of Anarchy, and actress Catherine Bell has a daughter called Gemma, as does Kristin Davis.
 Bottom line: A stylish cousin of Emma and Jenna.

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.

Jasper

Just like Flora is for botanicals, Jewel is the generic gemstone name, not used much since the early twentieth century, when it was seen as a symbol of how precious a daughter could be. The French version, Bijou, feels more modern, as do Pearl and Ruby. 

Jewel

Out-of-the-ordinary gemstone name derived from lapis lazuli, which is said to enhance awareness and intellect, impart ancient wisdom and cure many ailments, making it an interesting possibility for a blue-eyed girl. Lazuli — or Azure or Blue — are other options. 

Lapis

Onyx is one of the more masculine gemstone names but in recent years it's been a fast riser for baby boys and girls. Nick Cannon's daughter Onyx Ice may boost the name further.

Onyx

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

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage. The birthstone for the month of June, Pearl could also make a fresher middle name alternative to the overused Rose. Cool couple Maya Rudolph and Paul Thomas Anderson named their daughter Pearl Minnie, followed by Jack Osbourne, and several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .
After being a Top 25 name in the late nineteenth century, Pearl went into a long slide, but is showing signs of a strong comeback -- it reentered the Top 1000 in 2010.
 In Nathaniel Hawthorne's The Scarlet Letter, Pearl is the illegitimate daughter of Hester Prynne, who gives her the name because she is 'her mother's only treasure.'
 Pearl was also the alter ego name of Janis Joplin, tied to singer Pearl Bailey, and---hmm--the birth name of western writer Zane Gray.
 Variations are PERLE and PERLA.

Pearl

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.

Peridot

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.

Ruby

Sapphire goes waaaaay beyond Ruby and Pearl. This September birthstone, occasionally used a century ago, might be worth a reappraisal, perhaps as a Sophie/Sophia alternative. Sapphire is the pseudonym of Romona Lofton, who wrote the book Push, which was turned into the movie Precious. Sapphire entered the Top 1000 for the first time in 2022, and is proving to be one of the freshest gem names for girls. Another intriguing variation is the lovely Sapphira.

Sapphire

As a name, Topaz is sophisticated and sultry; as a golden gem, it's said to have healing and energizing properties and also to bring good luck-- and being the birthstone for November it's one of the perfect <a href="https://nameberry.com/list/605/names-for-november-babies">names for November babies</a>, with that final 'z' giving it some extra sizzle.
 The topaz gets its name via French and Latin from Greek; it is probably ultimately of oriental origin.
 There is an eponymous novel by Leon Uris--later made into a 1969 Hitchcock movie--in which Topaz was the name not of a person but a spy code name, and in the Dodie Smith novel I Capture the Castle, there is a character named Topaz Mortmain.
