This is a nice Lightning Ridge semi black opal and being a nondirectonal stone the color will always look at you from every angle.  That helps in the jewelry making process because it takes the difficult task of finding the best orientation for the stone out of the equation opening it up to many more design possibilities.  This opal is just large enough to look good anywhere you decide to wear it.
