  • Airbrush

Let's Get Started:


  • Using a shark knife, carve the bottom tier by rounding off the corners to create a pillow shape. Cover all the tiers with with fondant.


  • Heat up the edible gel for 20 seconds in the microwave - pour what you need into a cup and mix with a few drops of liquid blue color. Stir until combined to create a translucent blue.


  • Pour the blue colored edible gel into chocolate molds. Add a few more drops of undiluted color and using a toothpick, barely swirl the color into the gel to create a marbled effect. Let sit for a few minutes.


  • After the gel has set - it is ready to use. 


  • Create some decorative stones by adding more of the blue to the gel to make darker jewels. You could even add some metallic paint to create a shimmery effect as shown in the picture.


  • Carve some diagonal lines with a marking tool into the fondant on the bottom tier. In between those line carvings, press the smallest round cutter into the cake to make an impression.


  • Mix the rejuvenator and edible gold pigment together to create a paint (you can also use Everclear or clear lemon extract). Paint the bottom tier with an airbrush.


  • Adhere a gelatin gem over the top of the wafer paper using a little piping gel.



  • To create the marbled effect on the second tier, paint forms with the airbrush. You can also cut out some wavy shapes with wax paper for use as a template.


  • Using a clean paintbrush, paint some lines onto the middle tier using an aqua-colored gel paint. Allow to dry before adding some edible gold paint. Make as many lines as you like and allow the paint to dry and set.


  • Using the round cutters as a guide, wrap the floral wire around the cutter to form a circle shape and then secure together using white floral tape.


  • Pour some colored gelatin over the wired circle and allow to dry. Once dry, trim away the overhang to leave a clean edge. 


  • Using some 20-gauge floral wire, bend the wire over on itself as shown in the picture. Secure with white floral tape, and then dip the wire into the colored gelatin. Allow to dry.


  • Paint the visible floral wire with edible gold paint -allow to dry before adhering the decorations with royal icing or melted white chocolate to your cake.
