I used a picture of an opal that I bought from my friend Patrik who lives in Austrailia. Boulder Opals have the detail I need to make these designs. They come in every color and no two are alike. I also make jewelery from them.
Beautiful creation, Eleanor ... the design looks like a golden snowflake to me. I looked up Boulder Opal & see that they are unique in a variety of colors. Superb work.
