A large and fun stone. Perfectly colorless Opal without any play-of-color; what it does have though is a very strong reaction to shortwave UV light. Take a look at the ‘highlighter’ intensity in that second photo. This reaction is actually strong enough that you will see a mild reaction in regular daylight - just a little yellow-green at the edges, but definitely noticeable. Nicely cut and bright.
