Crystal Effect A To Z Alphabets

Prompt: Design an isometric letter “A” that is filled with shimmering crystals of various colors, each facet reflecting light, giving the impression of a precious gemstone structure. Additionally, integrate elements of water within the same letter, making part of it appear as a tranquil aquarium with fish and aquatic plants, creating a hybrid of crystalline and aquatic themes. The image should juxtapose the sparkling, geometric nature of crystals against the fluid, organic shapes of the underwater ecosystem, all within the confines of the letter “A”.
