Liliana exemplified the phrase 'too much,' and now moreso with Ignis, so why shouldn't their gifts?

"Oh you're welcome, darling," Liliana said with a slight wave of her hand to indicate that Lydia should think nothing of it. "You've spent how long herding cats to make sure we have somewhere to meet every Thursday? A few--" 'few' "--diamonds are a fitting sign of appreciation."

Ignis? Not think of the person who gave him a reason to go out and be social every week? Over his favorite (non-Liliana) thing? Tch, hardly.
