Who knew that diamonds ran in families? But for Joseph N. Wineroth III (Joel), owner of San Francisco’s acclaimed jeweler L.A. Giacobbi & Co., that is precisely the case.
The business began in 1886, when Louis A. Giacobbi opened a jewelry and gemstone wholesaling business in San Francisco’s Financial District. The Wineroth family became involved in the 1920s, when Joel’s grandfather merged his own jewelry business with the L.A. Giacobbi name, and a legacy was born.
The business passed into the hands of Joel’s father in the 1960s, and now Joel upholds the family’s commitment to offering patrons the utmost where fine jewelry is concerned.
We caught up with this third generation jeweler and gemologist at his eye-catching, appointment-only L.A. Giacobbi location on Maiden Lane in San Francisco. It was there that Joel answered a very important question.
How should one go about cleaning their jewelry at home?
Below, the official L.A. Giacobbi recipe for cleaning your diamonds, rubies and sapphires at home:
- Fill a small saucepan with 4”-6” of water.
- Add two tablespoons of powdered detergent (Ajax, Bon Ami, Comet or Tide). Stir and bring to a medium boil on the stove.
- Place jewelry in a small tea strainer or other small strainer that will suspend it in the liquid. Do not drop items into the pan.
- Boil for 10 to 40 minutes, checking at 10-minute intervals to see if the film has been removed from the stones.
- If necessary, use a small toothbrush to lightly brush the setting to remove the film. Let metal cool before handling, jewelry will be hot.
- Rinse the jewelry with cold water when finished, and dry with a lint-free cloth.
