Appearance
Under artificial light, the amber appears like ordinary amber, but under sunlight it has an intense fluorescent blue glow. When held against the sun it will appear like ordinary amber, and under ultraviolet light it will glow a bright milky-blue. This effect can be compared to the ocean, which, although transparent, can appear anything from light blue to dark blue to black, depending on depth, mass, salinity, etc.
Blue amber emits a very agreeable smell (aromatic molecules), which is different from regular amber when it is being cut and polished.

Famous quotes containing the word appearance:
“The President has paid dear for his White House. It has commonly cost him all his peace, and the best of his manly attributes. To preserve for a short time so conspicuous an appearance before the world, he is content to eat dust before the real masters who stand erect behind the throne.”
—Ralph Waldo Emerson (1803–1882)
“Do not look on his appearance or on the height of his stature, because I have rejected him; for the LORD does not see as mortals see; they look on the outward appearance, but the LORD looks on the heart.”
—Bible: Hebrew, 1 Samuel 16:7.
“Most lovers ... picture to themselves, in their mistresses, a secret reality, beyond and different from what they see every day. They are in love with somebody else—their own invention. And sometimes there is a secret reality; and sometimes reality and appearance are the same. The discovery, in either case, is likely to cause a shock.”
—Aldous Huxley (1894–1963)
