Suite: Tessellation Party! by Arya Akhavan (November 2012)

Well, the 2012 US elections were...interesting, to say the least. Some very Canadian-style (I'm Canadian!) ballot measures went through, so I figured I would name this design after how a friend of mine described the results. I prefer this in kunzite, but works from feldspar to rutile (RI = 1.52 - 2.62) with no changes. Suggested size = 6-12 mm
