While Baily's beads are seen briefly for a few seconds at the center of the eclipse path, their duration is maximized near the edges of the path of the umbra, lasting around 90 seconds. It is not safe to view Baily's beads or the diamond ring effect without proper eye protection because in both cases the photosphere is still visible. [5]
Diamonds of more intense color (usually yellow, but in some cases red, green or blue) are termed fancy color diamonds. Black diamonds are also fancy color diamonds. All other factors being equal, the most valuable diamonds are those with the least color (appearing white to the eye), and those possessing vivid color ( especially yellow, pink ...
Gemstone irradiation is a process in which a gemstone is exposed to artificial radiation in order to enhance its optical properties.High levels of ionizing radiation can change the atomic structure of the gemstone's crystal lattice, which in turn alters the optical properties within it. [1]
Only one percent of natural diamonds are of this type, and most are blue to grey. [30] Boron is an acceptor in diamond: boron atoms have one less available electron than the carbon atoms; therefore, each boron atom substituting for a carbon atom creates an electron hole in the band gap that can accept an electron from the valence band .

Theoretically, pure diamonds would be transparent and colorless.
