Most gems, like malachite do not have a widely accepted grading system like diamonds do, so terms like "AAA grade" are relatively meaningless and more clever marketing than anything else. One seller's purported "top quality grade AAA" material might be very different from anothers. Generally, what you're seeking in top grade malachite is material that has good bright color, contrasting banding, attractive patterns, no soft spots, no cracks, no pitting, and no inclusions of other minerals. An exception to the latter would be when malachite is combined with azurite, which makes for a fabulous and colorful gem.
