New logo for Opal Mining business called "Rainbow Chaser".

This is what "Rainbow Chaser". [May include "Opal Mining since 2007".] was looking for in their logo design

I am needing a new logo for my new business called "Rainbow Chaser". This is a mining business. We mine opals in Coober Pedy, outback Australia. Opal displaying all the colours of the rainbow. Please do a search on opals before starting your entry. The logo has to portray opals and colour. Please steer away from any LGBTQI references which would include the traditional rainbow as we do not want our business confused with the movement. Think "light diffraction"(when light splits into colour passing through a prism). Iconic machinery like "Opal Mining Blowers" or excavators can be used if you like. We want it simple, appealing and needs to quickly get the points "Opal Mining" and "Coulour" across. Read more
