Bella Hadid's Dress at the Cannes Film Festival 2017

We admittedly get excited over red carpet dresses (there have been so many great ones), but when we saw Bella Hadid at Cannes, her custom Alexandre Vauthier gown wasn't what caught our eyes. Instead, it was her enormous necklace: a square blue stone attached to a silver chain. The sapphire creation immediately reminded us of the one in Titanic.

Rose wears a blue heart-shaped diamond —‚ you know, the "Heart of the Ocean" — in the film, and the colour's intense shade matches Bella's perfectly. Though the model's gem is more of a square than heart, we can totally see the parallels between the two necklaces. See for yourself by scrolling through the photos ahead.
