Finding the Right Necklaces for You

We are fortunate to know much of the world’s long and dazzling history of necklaces, as this type of jewelry was so treasured that it was frequently buried with its owners.

Lapis lazuli beads adorned necklaces unearthed from the royal graves at the ancient Iraqi civilization of Sumer, while the excavation of King Tut’s burial chamber revealed a sense of style that led to a frenzy of Art Deco designs, with artisans of the 1920s seeking to emulate the elegant work crafted by Ancient Egypt’s goldsmiths and jewelry makers. 

In ancient times, pendant necklaces worn by royalty and nobles conferred wealth and prestige. Today, wearing jewelry is about personal expression: Luxury diamond necklaces exude confidence and can symbolize the celebratory nature of a deep romantic relationship, while paper-clip chain-link necklaces designed by the likes of goldsmith Faye Kim are firmly planted in the past as well as the present. Kim works exclusively with eco-friendly gold, and these fashionable, fun accessories owe to the design of 19th-century watch fobs. 

For some, necklaces are thought of as being a solely feminine piece, but this widely loved accessory has been gender-neutral for eons. In fact, just as women rarely took to wearing a single necklace during the Renaissance, men of the era layered chains and valuable pendants atop their bejeweled clothing. In modern times, the free-spirited hippie and counterculture movements of the 1960s saw costume-jewelry designers celebrating self-expression through colorful multistrand necklaces and no shortage of beads, which were worn by anyone and everyone. 

Even after all of these years, the necklace remains an irrefutable staple of any complete outfit. Although new trends in jewelry are constantly emerging, the glamour and beauty of the past continue to inform modern styles and designs. In a way, the cyclical history of the necklace differs little from its familiar looped form: The celebrated French jewelry house Van Cleef & Arpels found much inspiration in King Tut, and, now, their Alhambra collection is a go-to for modern royals. Vintage necklaces designed by David Webb — whose work landed him on the cover of Vogue in 1950, two years after opening his Manhattan shop — were likely inspired by the ornamental styles of ancient Greece, Mesopotamia and Egypt

On 1stDibs, browse top designers like Cartier, Tiffany & Co. and Bulgari, or shop by your favorite style, from eye-catching choker necklaces to understated links to pearl necklaces and more. 

Questions About 18 In Diamond Necklace
  • 1stDibs ExpertNovember 8, 2023
    Whether an 18-inch necklace is too short depends on a few factors. If the necklace length causes it to hit right at the neckline of your top, you may want to go with a longer or shorter option. People with wide or short necks may also find necklaces longer than 18 inches more flattering. On 1stDibs, shop a variety of necklaces.
  • 1stDibs ExpertFebruary 22, 2021
    The cost of a diamond necklace can range quite a bit depending on material, craftsmanship, quality, and condition. On 1stDibs.com, you can shop a variety of diamond necklaces at a range of prices. Browse contemporary and antique necklaces starting at $125.
  • 1stDibs ExpertNovember 8, 2023
    Whether an 18- or 20-inch necklace is better depends on a variety of factors. Generally, a necklace should fall above or an inch or so below the neckline of what you're wearing, so you'll want to keep your tops and dresses in mind as you choose pieces. People with wider or shorter necks may prefer longer necklaces, while those with longer or narrower necks may be best flattered by longer styles. Also, you may find one length more comfortable or visually appealing than another based on your preferences. Shop a large collection of necklaces on 1stDibs.
  • 1stDibs ExpertMay 5, 2023
    Whether a diamond necklace is a good gift is largely a matter of preference. However, diamonds offer timeless appeal, and with respect to styles, all kinds of diamond necklaces have been made over the years, which means you’ll have a lot of options when it comes to shopping for a gift. From “A Diamond Is Forever” to “Diamonds are a Girl’s Best Friend,” pop culture has ingrained in our minds that diamonds are the most desired, the most lasting and the most valuable gemstone. They are the hardest gemstones, and diamonds are quite rare, according to the Gemological Institute of America, and only 30 percent of all the diamonds mined in the world are gem quality. Shop a selection of diamond necklaces on 1stDibs.
  • 1stDibs ExpertNovember 6, 2023
    There is no hard-and-fast rule for how many carats a diamond necklace should be. On average, solitaire diamond necklaces range from 0.5 to 1 carat, but you can find pieces with larger and smaller stones. Tennis chains that feature continuous diamonds set into links usually have much higher total carat weights. For example, one might feature 60 individual diamonds, each 0.20 carats in size, for a total carat weight of 12.0 carats. Shop a wide range of diamond necklaces on 1stDibs.
  • 1stDibs ExpertOctober 19, 2021
    Tiffany diamond necklaces are dazzling and covetable pieces of jewelry. Tiffany & Co. is one of the most prominent purveyors of luxury goods in the United States, and has long been an important arbiter of style in the design of necklaces as well as diamond engagement rings. When a jewelry enthusiast mentions “the Tiffany Diamond,” this refers to the 128.54 yellow-carat Tiffany Diamond, which was found in the Kimberley diamond mines in South Africa in 1877. This jewel was worn by pop music icon Beyoncé in a 2021 ad campaign. The estimated value of the Tiffany Diamond in 2019 was $30 million. Shop a range of antique and vintage Tiffany diamond necklaces on 1stDibs today.

    Whether you should get an 18-inch or 20-inch necklace depends largely on where you want the piece to fall. An 18-inch, or princess-length, necklace usually hits just below the collarbone and can work well for displaying pendants. A 20-inch, or matinee-length, necklace will rest a little further below the collarbone and can be ideal for creating layered looks with other necklaces. On 1stDibs, shop a wide variety of necklaces.
