  2. Belomorite - Wikipedia

    en.wikipedia.org/wiki/Belomorite

    Belomorite is a spectacular, inexpensive and popular ornamental stone; it is used in jewelry as one of the varieties of “moonstone”. It is typically cut into cabochons , often double-sided, convex in both directions, thus enhancing its brilliance, unlike, say, similar labradorite , which is often cut into flat plates cut parallel to the ...

    The moonstone is the Florida State Gemstone; it was designated as such in 1970 to commemorate the Moon landings, which took off from Kennedy Space Center. However, it does not naturally occur in the state. [6] In Thailand, moonstone is known as Mukdahan, the same name as the northeastern province next to the river Mekong, Mukdahan.

    Opalite is a trade name for synthetic opalescent glass and various opal and moonstone simulants. Other names for this glass product include argenon, sea opal, opal moonstone, and other similar names. [1] [2] It is also used to promote impure varieties of variously colored common opal. [1]

    Adularescence in a moonstone cabochon, Minas Gerais, Brazil. The specimen's diameter is 23 mm (0.91 in). Adularescence (/ ˌ æ dʒ ə l ə ˈ r ɛ s ən s / AJ-ə-lə-RES-əns) is an optical phenomenon that is produced in gemstones like moonstone. The optical effect is similar to labradorescence and aventurescence.

    Normally, in grading colored gemstones, color is by far the most important criterion. However, in the grading of emeralds, clarity is considered a close second. A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency to be considered a top gemstone.

  8. Quantum chromodynamics - Wikipedia

    en.wikipedia.org/wiki/Quantum_chromodynamics

    The force between quarks is known as the colour force [6] (or color force [7]) or strong interaction, and is responsible for the nuclear force. Since the theory of electric charge is dubbed "electrodynamics", the Greek word χρῶμα (chrōma, "color") is applied to the theory of color charge, "chromodynamics".

  9. Color charge - Wikipedia

    en.wikipedia.org/wiki/Color_charge

    Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
