Abstract
Apparatus for exhibiting grains of precious stone comprises in a container assembly at least two communicating compartments, which communicate with each other through at least one passageway, which constitutes a singling path for grains of precious stone. That communicating passageway is constricted so as to permit singled grains having a given size to move freely through the passageway. The container assembly contains an aggregation of grains of precious stone. The at least two compartments communicating with each other have different elevations. The communicating passageway is defined by a slideway, which is inclined from the vertical, or constitutes a path for a free fall of grains of precious stone from the aggregation. Such apparatus can be used as a sales display container, an ornament, or a gift article.
