Swarovski crystals help!

[Spectrum Nails]

I'm looking to invest in some Swarovski but there are so many colours and sizes, I'm not sure what to get.
Can anybody recommend what to go for to get me started?
Are those any good?

Thx

Those aren't crystals, that's crystal pixie which is different.
Scatter crystals sell packs containing different sizes in clear and AB which is a good start.
