Round tiers, no hexagons like the bottom pic. Any tips, techniques, products, tools, advice, youtube video links...anything that you have to share to help me achieve this look would be helpful! 

Thank you!

Marble is rather easy  just touch a tiny bit of black color in just one or two spots and knead lightly  then roll out.              For the gold lines roll fondant strings then paint w/gold highlighter dust mixed w/vodka or similar
