Abstract: A decorative lava lamp includes a housing having one or more dense fluids therein, with discrete granules, such as gems or diamonds floating therein, wherein the lava lamp includes a light underneath. A lamp base both illuminates the lava lamp and heats the one or more dense fluids. The internal illumination from the bottom adds a decorative dimension that cannot be duplicated by external lighting. The brilliant gems sparkle and throw off shadows in the vicinity when placed in a dimly lit area. The heated silicone fluid rises in the center of the lower portion of the lava lamp lifting gem granules within the housing where they gently fall again due to the cooling of the silicone oil in contact with the enclosure. This creates a dynamic light show.

Abstract: An hourglass timepiece that is filled with a plurality of precious or semi-precious stones, such as small uncut diamonds, which are suspended in a silicone compound, such as silicone oil, to prevent scratching of the interior surface of the hourglass as the stones move by gravity from an upper compartment to a lower compartment of the hourglass. The hourglass has similar ends, either of which can be supported by a decorative base that reflects light into the stones to highlight them and compensate for the reflective loss due to the silicone.
