Color Diamond Z Ring
At first I was amused by the brief's request for colorful crystal, but colors are good and I like them pure, shinny and well saturated which is still big trend on logo design. It was relatively easy to recreate Z crystal but just after playing a lot with colors, shading, overlays I manage to get this shine through effect of something that might resemble quality crystal glass, or maybe even a diamond. Putting Z in the C letter was easy, but I think there might be something in option where Z looks like stone in the ring. I am sure I like this option better. For Typography I have chosen fresh Roman based typeface, Cinzel Regular font that suited best to associate with expensive jewelry store. I hope you will like this.
