Abstract: A gemstone arrangement is described including a primary gem and at least one complementary gem. The primary gem includes a crown and a pavilion. The pavilion has an external wall defining an outer surface. The complementary gem has a crown defining a table. The table is in juxtaposition to and aligned with the pavilion wall for the maximum passage of ambient light from the complementary gem into the primary gem to enhance its visual appearance. In addition, the complementary gem has the same, but more intense color as the primary gem to intensify the color of the primary gem so a weak colored primary gem can appear intensely colored.
Abstract: The present invention is directed to a cleaning sponge. The cleaning sponge contains a cavity that is cut radially inward through one of the sides of the sponge. The cavity is located closer to the side of the sponge rather than its center. Furthermore, the sponge has two holding arms that are formed when the cavity is cut and form a channel, allowing the sponge to be placed on a faucet or any other hanging member. The holding arms pull apart when the sponge is placed on a faucet and once the sponge is on the faucet, they pull together. Since the cavity is near the side of the sponge, the holding arms do not interfere with the cleaning function of the sponge. Furthermore, the sponge has several layers with different coefficients of coarseness for cleaning different surfaces and may be cut in any decorative shape desired.
