Clean your gold
jewelry on the cheap. The following applies to gold alone or with all stones but for opals, pearls, turquoise, mother-of-pearl, or any other delicate stone.
Take out a coffee mug. Put one single drop of dishwashing liquid (for dishes by hand, not the dishwasher type) in the bottom and fill with LUKEWARM water. Carefully place the ring, bracelet or necklace you wish to clean on the bottom. Leave overnight. In the morning you will find a lot of dirt specks floating on top. Rinse
jewelry gently with warm (never hot) water and dry thoroughly. Warning: Again, NOT for use with opals (which absorb water and are sensitive to extreme heat and cold) or turquoise or pearls, or any other stone which might absorb the water or be damaged by it or the chemicals in the dishwashing liquid.
