Gold filled Chai necklace Available in ♡ 16" ♡ 18" ♡ 20" The Hebrew word chai (חי) is a popular Jewish symbol that means "life" and is often associated with good luck and blessings. It's made up of two Hebrew letters, chet (ח) and yud (י), which have numerical values of 8 and 10, respectively, adding up to 18. Because of this, Jews often give gifts of money in multiples of 18, such as at weddings, bar mitzvahs, and when making donations, to symbolically give the recipient the gift of "life" or luck. This custom is also known as "giving chai" and multiples of 18, such as 36, are sometimes called "double chai". Gold-filled jewelry features a thick layer of gold bonded to a base metal, making up at least 5% of its weight, which ensures greater durability, longevity, and resistance to tarnishing compared to gold-plated jewelry, which only has a thin layer of gold. Gold-filled pieces also look and feel closer to solid gold, are less likely to cause allergic reactions, and, while more expensive than gold-plated items, they are more affordable than solid gold.
