Boulder Opals, in particular, serve as beautiful reminder that without breaking, we make no room for rainbows. The Opal forms in the rock’s broken places. 
Let that sink in.
The most beautiful part is what fills the broken places… a good lesson to us all that there is beauty in breaking. 
Ethically sourced Boulder Opal set in sterling silver with fine silver bezel in my rainbow setting. Hung from a sterling chain.
