An origami gemstone I designed based on Spike the dragon's heart-shaped fire ruby. The model is full 3D and measures 5 inches across at the widest point. Fortunately I am quite happy with how the general shape turned out. This was folded with red/green duo paper(I just ignored the green and tucked it inside, I was trying to find the reddest paper I had). I imagine it would look even more awesome with a reflective red/maroon paper, but alas I don't have such paperI'm not actually sure how many other heart shaped gemstones are out there but I tried to make it more distinctive to the show's depiction by recreating the number of edges and the central diamond shaped facet.The stand was a quick design, as the ruby looked much nicer standing up.The actual ruby has more facets, but attempting to add more was too headache-inducing. What should have been a relatively straight-forward crimp session became frustrating as paper layers and shape dimensions came into play.Crease pattern here: [link] Guide to using the crease pattern: [link]
