Brilliant (diamond Cut) - Hearts and Arrows Phenomenon

Hearts and Arrows Phenomenon

A diamond that has the top facet or "table facet" exactly perpendicular to the bottom of the diamond or "pavilion" and has its other facets precisely aligned with excellent symmetry, may show patterns that look like arrows from the top and hearts from the bottom. Generally it will need to be viewed loose under a gemscope to see the pattern very well. Although the hearts and arrows property is indicative of a top-tier cut, it does not always mean the diamond will be the most brilliant. Optimal facet placement is the key to brilliance and more important than facet patterning. Not all ideal round cuts will have the hearts and arrows effect either.

Famous quotes containing the words hearts, arrows and/or phenomenon:

    At a certain age, we have already been struck by love; it no longer develops alone, according to its own mysteries and fateful laws while our hearts stand by startled and passive. We come to its assistance ... Recognizing one of its symptoms, we recall, we bring back to life the others. Since we possess its song engraved in its totality within us, we do not need for a woman to tell us the beginning—filled with admiration inspired by beauty—to find the continuation.
    Marcel Proust (1871–1922)

    Your master Robin Hood lies dead,
    Therefore sigh as you sing.

    Here lie his primer and his beads,
    His bent bow and his arrows keen,
    His good sword and his holy cross:
    Anthony Munday (1553–1633)

    The teacher must derive not only the capacity, but the desire, to observe natural phenomena. In our system, she must become a passive, much more than an active, influence, and her passivity shall be composed of anxious scientific curiosity and of absolute respect for the phenomenon which she wishes to observe. The teacher must understand and feel her position of observer: the activity must lie in the phenomenon.
    Maria Montessori (1870–1952)
