In a mixing container, pour in fresh orange juice, fresh pineapple juice, and freshly squeezed lime juice. Add orgeat syrup and simple syrup, adjusting sweetness to your preference. Stir well using a spoon until fully blended.

Grab old-fashioned glasses and fill each one generously with crushed ice, packing it well to create a solid base.

Carefully pour the chilled juice mixture over the crushed ice in each glass until nearly full.

Slowly drizzle grenadine into each glass, pouring it gently down the side to create a stunning gradient effect.

Consider topping each glass with club soda or sparkling water for extra fizz, pouring it slowly to maintain the layered look.

Garnish each drink with orange slices, a maraschino cherry, and a mint sprig. Serve immediately for the best experience.
