How much is 1 kg of saffron?

Excuse me, could you please clarify the price for one kilogram of saffron? I'm interested in purchasing some, but I'm not sure of the current market rate. Is there a specific grade or quality of saffron that you are referring to, as I understand there can be significant variations in price depending on these factors? Additionally, could you also provide any insight into any potential fluctuations in price or any trends that I should be aware of before making my purchase? Thank you for your time and assistance.
