Queen of Diamonds

Hooray, I finished a birthstone design before 1am!  lol small victories...

April's birthstone is diamond... except I found out while researching this that as of 2013, in Britain, there's a secondary birthstone - rock crystal (ie, quartz).  Lucky me, quartz and diamond are most commonly colourless, so I didn't have to deviate too far from what I had in mind. 

I've tried to include a bit of representation for every diamond colour here, although some are so tiny you might not be able to really see them.  My personal thoughts about the diamond industry aside, who doesn't love a good, sparkly diamond, refracting rainbow light like a prism?  >w>
