Opinions on girl names?

Sooo I’m planning ahead for what I wanna name my kids, and hubby & I have already agreed to have 3 more. If they do happen to all be girls, I want them to kinda “go together”, if you know what I mean. I personally think it’s super cute, but would like others opinions. The 3 names I have picked out are Juliette, Gemma, & Crystal. How on earth do they go together some of you may be thinking; well I’m thinking of it as Jules (Jewels), Gems, & Crystals 💗
