Harder than Rock

This is a logo design for a startup company which will be designing streetwear hats with eccentric look. When i first discussed with the client he made clear to me that diamonds and gold would be used as the basic decorative elements on the hats. Moreover he wanted to decorate the logo with different materials so the logo design should be simple and compact. I found a way by designing a rhombus (diamond) penetrated by something much harder. ‘Harder than Rock’.
