This time I got something special for You: Partly polished nice color blue/orange/brown amber. Strong fluorescence under UV light. Pictures were done with strong artificial light. Was hard to take pic, but when You will take this piece outside in sunny day You will see that it's blue. Blue color is visible in UV light and in strong sunlight. Condition as on pictures Great collection specimen much better in person. Not Coba. Feel free to do laboratory tests.
