Grey Spinel buying advice

[LD]

the color preference is indeed different for everyone，Maybe I think more about rare attributes, Gray-blue and gray-violet spinels are very easy to find, but gray spinels without other hues are actually relatively rare

I don’t disagree but (and this is personal preference) I find them cold. Interestingly I have a grey diamond that is grey but because of the facets the different colours I see from the fire makes the difference between looking warm and cold.
