The Seldom-Seen FireAs soon as I spotted the tiny pocket of brilliant green fire in this otherwise somewhat unremarkable piece of Mexican opal which is mostly the orange and white matrix stone in which the opals are found I knew I had to pair it with chrome diopside, which is the exact same shade of vivid green. I added orange color treated opals with green flash to pull it all together. Theres a lot of fire in here, but you have to know where to look.
