These are gorgeous and very flashy pieces of labradorite that have been put together in mosaic style.
Please view carefully, you will see in some photos there are some airholes which happened. It doesn't detract at all but I wanted to point it out for those who need to know.
They measure about 4 3/4" across so are large and nice. They are also just over 1/4" thick.
I have a limited number of these.
