How to tell one opal from another

White opals, on the other hand, are almost creamy and sometimes called milk opal. Because they are white, they do not show the inner color as well as black opals and are generally only bought as white opals. However, some color flashing can still be seen in an excellent quality opal gemstone. These can be purchased relatively cheaply, although really high-quality ones can cost you a few hundred or a thousand dollars.
