This time I got something special for You: A unique set of 23 natural amber stones from Sumatra, Indonesia, each piece preserving the memory of ancient tropical forests through fossilized wood inclusions. Their deep brown, golden, and honey tones reveal fascinating inner structures, with some showing rare swirling patterns. Under UV light, these ambers come alive with a mystical glow, enhancing their collector’s value. This lot is perfect for collectors, carvers, or anyone fascinated by the timeless beauty of fossil resins. 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 bluish color. 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.
