In general, black cards are more advanced, but they also have different situations.

First of all, the black gold card is the black gold (highest) version of the "Centurion Series Debit Card" launched by American Express in the UK in 1999. Since the main color of the card surface is Black, so it is also called "black card".

The diamond card is a high-end credit card or savings card jointly launched by bank card organizations and commercial banks and other institutions.

Black Gold Card cardholders are mostly political figures, billionaires and celebrities from various countries and are invited by American Express. Card applications are not accepted. Cardholders can enjoy the world's top member-exclusive benefits, rights and services.

In addition to all financial functions, the Diamond Card also provides a 24-hour exclusive service hotline, online banking services, account change SMS reminder services, and counter priority services.

Having a black card in your hand means you have the right to let people from all over the world serve you. The widely circulated story about black cards proves this point. If the cardholder wants to travel to the world, as long as it is something that people on earth can do, American Express will try its best to satisfy it. Such instances have appeared many times in film, television and animation works.

The Diamond Card is equipped with value-added services such as public traffic accident insurance, airport VIP lounge services, health exclusive medical care, golf reservation services and financial management butlers. In addition, the card-issuing bank has equipped the card with personal butler service, exclusive club reservation service and professional consulting services.
