I will not be helpful since not a fan of guilloche but Of your options I would save for dismond in magic and get something else in vintage (mop, malachite,onyx, etc). For mop the inbetween magic and vintage is a nice size too. It doesn’t have as much length option with the chain but it is such a great size.
Maybe VCA should consider a in-between size for the Pave as well, if people do not wear the Pave as a long necklace...
