Talk:Akhavan - Triforce
I've written two designs that mimic the Triforce from Legend of Zelda. This modified design is much less cushion-y, and thanks to using the 95/1 and a very steep, tiny set of C1 facets, it looks almost exactly like the Triforce. The reflection pattern is...interesting, and definitely bright. It kinda looks like a Sierpinski triangle, with a bit of bite to it. If you want to go for a really, REALLY obvious triforce, you can scale the crown up by 1.7 - you'll get a perfect Triforce pattern, but you'll have a really wonky-looking gem that'll be balls-hard to set.
This pattern definitely can NOT be cut in opal or fluorite without some serious optimization, but can be cut in materials from feldspar to high zircon (RI = 1.52 - 1.93). Above that, it starts to look silly. There's also not a lot of dispersion coming out for zircon, so if you're going for a higher RI material I'd recommend synthetic corundum.
As a side note, this is a surprisingly good design for shorter crystal tourmaline with some superficial cracks or rind. Orient the table along the C-axis, and when you cut the girdle you'll grind out the rind and cracks.
There's nothing tricky about cutting this. Nothing. This would make a great beginner's stone, for a first-time triangle (although I'd recommend not using tourmaline as a beginner). It would even be really easy to set, since it's shallow.
Difficulty level = low beginner
