A jewelry expert shares an estimated value for the 'obscure' piece of jewelry and tells PEOPLE what makes the customized gift is so special

The gift in question was a gold diamond necklace that has “Skibidi Toilet” engraved on it, with “Love, North” engraved on the other side. In the video Kardashian shared on her Instagram story, North seemed thrilled to give her mom the present, saying her mom loves “Skibidi Toilet.” “I do?” Kardashian asked with a laugh.

"Okay, North got me this diamond necklace that says Skibidi Toilet. Wow," Kim said, holding back a laugh. "And, 'Love, North,'" the proud gift giver chimed in, explaining "because you love Skibidi Toilet." "I do?" a confused Kim responded.
