Who qualifies for the Black Card?

Excuse me, I was wondering, could you please elaborate on the qualifications necessary to be eligible for the prestigious Black Card? Is it based solely on a certain level of financial assets, or are there additional criteria that need to be met, such as a specific credit score or membership in an exclusive club? I'm quite intrigued by the exclusivity and benefits it offers, and I'm eager to learn more about the process of acquiring one. Thank you in advance for your time and insight.
