How much is an extra Kyber crystal?

Excuse me, could you please clarify the value of an additional Kyber crystal? I'm interested in understanding the market price for this particular cryptocurrency asset. As an investor, it's important for me to assess the potential return on investment before making a decision. Is there a standard price range that these crystals typically trade within, or does it vary depending on factors such as demand and supply? Additionally, are there any specific platforms or exchanges where I can buy and sell Kyber crystals with ease and transparency? Thank you for your assistance.
