How much is 1000 diamonds on TikTok?

Excuse me, as a cryptocurrency and finance expert, I'm curious to inquire about the valuation of virtual currencies in social media platforms. Specifically, I've noticed that TikTok has its own currency system with diamonds, which are often used as a form of reward or recognition for creators. Could you please elaborate on the current market value of 1000 diamonds on TikTok? Is there a set exchange rate or is it subject to fluctuations based on demand and supply? Additionally, how does one acquire these diamonds and what are the implications for their use within the platform? I'm interested in understanding the economic aspects behind this digital currency.
