Help choosing a daily necklace/personal birthday present

Hello everyone,
Please provide some insight on a pleasant dilemma. I am currently quite interested in the Cartier love neck lace pink gold with diamonds interlocking rings (REF: B7224528) and the Tiffany Victoria pendant in yellow gold, medium size. Both are similar price points. I had the chance to try on Victoria in rose gold, which was lovely. I saw the Cartier necklace on a recent trip to Las Vegas and I can’t stop thinking about it. Does anyone own either one and can share some info regarding them? Thanks!
