01 - Using a sharp knife or round cookie cutters, slice melons into even, circular rounds. Optionally, use different-sized cutters to create smaller circles for layering.
02 - On a large serving platter, arrange the largest melon circles in a single layer, alternating colors for visual appeal.
03 - Layer smaller melon rounds atop the larger ones, forming concentric rings with varying melon types for contrast.
04 - Scatter strawberries, blueberries, raspberries, and blackberries liberally over and between the melon layers.
05 - Garnish with fresh mint leaves and sprinkle lime zest over the arrangement, if desired.
06 - Serve immediately or cover and chill until ready to present.
