Sketch inspired by the colors of Onyx and Sardonyx (red onyx). Looking forward to coloring it!

For the Gemstone Streak.

I was inspired by the various colors of onyx. Black of course is the most well-known, and the sardonyx (red) variety is beautiful as well. This illustration will take place in the dark of night (for onyx) and her dress, gemstone clasps, and fairy lights will be red for sardonyx.
