Kate Middleton has plenty of jewelry in her drawers to choose from at any given moment 鈥 there鈥檚 the Collingwood pearl drop earrings she inherited from Princess Diana or the famous blue sapphire engagement ring from her royal hubby. Still, it鈥檚 not always the priciest pieces the Duchess of Cambridge reaches for. In fact, there鈥檚 one necklace in particular that she wears on the reg that you can snag for less than $130!

The piece in question is Merci Maman鈥檚 aptly named The Duchess Necklace ($129), which Kate received as a gift from her younger sister back in 2013 after the birth of her son. As Maman explained in a recent blog post, the gift was not only sentimental because of its giver, but because of the meaning behind it.

Pippa reportedly got the necklace engraved with a pendant bearing Prince George鈥檚 full name, a little gold-plated boy charm, along with a small 鈥淲鈥 (for William) charm. And aside from being thoughtful, the necklace is full of significance: It鈥檚 also a nod to a similar piece the Duchess鈥檚 mother-in-law used to wear!

鈥淭he young Lady Spencer owned a simple gold chain bearing her initial 鈥楧,'鈥 the blog revealed. 鈥淯pon the birth of Prince William in 1982, Prince Charles gave Diana the gift of a gold pendant engraved with their new son鈥檚 name, which she always wore close to her heart.鈥 By giving Kate her own gold-plated pendant with Prince George鈥檚 name on it, Pippa was helping her big sis to carry on the tradition. Aww!

That Duchess Necklace is still available on the site, with options to customize it as your own by choosing the metal (Kate wears the gold-plated version, but sterling silver is also up for grabs), the number of boy or girl charms you need, and your baby鈥檚 name and date of birth. Here鈥檚 your chance to snag a piece of Middleton鈥檚 jewelry box for less than $150!
