Some jewelry is meant to be noticed. Chai isn't. It's two small Hebrew letters, worn close to the throat, the kind of necklace you put on once and quietly never take off. It shows up on pendants, in wedding toasts, and in the size of a check written for a bar mitzvah gift, all pointing back to the same idea: life is worth celebrating, and worth wearing.
What Does Chai Mean?
Chai (חי) is the Hebrew word for "life," "living," or "alive." It's spelled with two Hebrew letters, chet (ח) and yud (י), which together are often worn as a pendant or engraved into jewelry as a stand-in for the word itself. The related word chaim, the plural form, appears throughout Jewish prayer and celebration, most familiarly in the toast "L'chaim," meaning "to life."
Why Is the Number 18 Connected to Chai?
The number 18 is connected to chai because of gematria, a Jewish system that assigns a numerical value to each Hebrew letter. Chet has a value of 8 and yud has a value of 10, and together they add up to 18 (My Jewish Learning, 2026). Because chai means life, 18 became known as a number associated with life and good fortune.
This is why Jewish gift-giving and charitable donations are frequently made in multiples of 18, 18, 36, 54, and so on, a practice often called "giving chai." Many Jewish charities suggest donation amounts in multiples of 18 for exactly this reason, which is a nice thing to know the next time you're picking a number for a gift card, or, for that matter, a necklace worth giving.
How Old Is the Chai Symbol?
The Chai symbol as jewelry dates back to at least medieval Spain, making it one of the older continuously worn Jewish symbols still in circulation, with its popularity as a pendant growing further in 18th century Eastern Europe (Judaica Webstore, 2023). Using Hebrew letters as symbols goes back much further still, rooted in the belief that the world itself was formed from the letters that make up the Torah. It's rare for a piece of jewelry to have that much history behind something so small and so simple to wear.
Is Chai a Religious Symbol, or Just a Cultural One?
Chai carries both meanings at once. It's rooted in Jewish text and tradition, referenced in the Torah and connected to Kabbalistic teaching, but it also functions today as a marker of Jewish identity, pride, and connection to community, worn by people across a wide range of religious observance. Notable public figures who've worn a Chai necklace, including entertainers with Jewish heritage or family ties, have helped keep the symbol visible well outside strictly religious contexts, proof that a piece can be deeply meaningful and still look effortless with a white tee.
How Do You Wear a Chai Necklace?
Chai is a small pendant by design, meant to sit close to the neck, either on its own or layered with other meaningful jewelry. MyAleph's Chai necklace sets the symbol as a small silver pendant with a single white stone, built to be worn every day rather than saved for special occasions. Layer it with an evil eye necklace like Luna or Lola for a stack that mixes two different, personal forms of meaning, or let it stand entirely on its own for something quieter, the kind of necklace that ends up in every photo without you ever noticing you're wearing it.
FAQ
Do you have to be Jewish to wear a Chai necklace? Chai is a specifically Jewish symbol rooted in Hebrew language and tradition, so it's most commonly worn by Jewish people or those with a personal connection to Jewish heritage or community, more so than symbols like the evil eye that developed independently across many cultures.
Why do Jewish people give gifts in multiples of 18? Because the Hebrew letters that spell chai (life) add up to 18 in gematria, giving a gift in multiples of 18 is a way of symbolically wishing someone a long life.
What's the difference between Chai and the Star of David? Both are recognized Jewish symbols, but they represent different things. The Star of David is a broader emblem of Jewish identity and faith, while Chai specifically represents the value and celebration of life.
Can a Chai necklace be layered with other jewelry? Yes. Chai is a small, understated pendant that layers easily with other necklaces, including symbols like the evil eye, without competing for attention.
Is "chai" pronounced like the tea? No. The Hebrew chai is pronounced with a guttural "kh" sound, closer to the "ch" in "Bach," while chai tea uses a softer "ch" sound like in "chocolate." Both happen to rhyme with "high."
The Bottom Line
Chai packs an entire philosophy into two small letters: life is worth living, worth celebrating, and worth giving thanks for. Worn as a necklace, it's a quiet daily reminder of something a lot of louder jewelry tries, and fails, to say.
