Jewellery Care Guide

Paris Argentina’s Comprehensive Jewellery Care Guide

Welcome to our jewellery care guide. At Paris Argentina, we understand the joy of wearing a stunning piece of jewellery, and we’re here to help you keep your treasures looking their best. This guide covers cleaning and maintenance tips for gold, silver, gemstones, opals, and pearls, as well as advice on caring for softer gemstones.

Gold and Diamonds

To keep your gold and diamond jewellery shining brightly, follow these simple steps:

  1. Place your gold piece in a dish of warm, soapy water (dishwashing liquid or hand soap are both fine).
  2. Allow it to soak for a few minutes, then gently scrub it with a soft, old toothbrush, paying special attention to the stones.
  3. Rinse and dry with a soft polishing cloth.

If your gold earrings and rings become tarnished over time, consider using a gold polishing kit with a non-toxic jewellery cleaning solution. For precious gemstones such as diamonds, rubies, sapphires, and emeralds, you can take them to a reputable jewellery shop for professional cleaning using an ultrasonic cleaner. Alternatively, you can invest in a small ultrasonic cleaner for home use to keep your jewellery sparkling all the time.


Silver tarnishes more quickly than gold due to a chemical reaction with air and other substances. To slow down the tarnishing process:

  1. Avoid wearing silver when gardening, cooking, doing the dishes, swimming, or taking a bath (chlorine will tarnish silver immediately).
  2. Put your jewellery on after applying makeup and perfume.
  3. Be mindful that silver necklaces may tarnish more quickly if worn with wool.

Store silver in tightly sealed plastic bags, with a piece of chalk or a small bag of silica gel to absorb moisture and delay tarnishing. To clean silver, use a silver polishing cloth or a cleaning solution like Silvo, and a very soft toothbrush or cloth to prevent scratches. Alternatively, make your own silver jewellery dip with hot water, salt, and baking soda in a tin foil-lined glass container. Leave your silver pieces in the dip for about five minutes, then rinse with water and dry with a soft cloth.

Caring for Medium and Softer Gemstones

Medium to soft gemstones include a range of stones that fall between 4 and 7 on the Mohs hardness scale. These gemstones require a bit more care than harder gemstones to prevent damage or scratches.

The Mohs scale is a useful tool to help determine the durability of gemstones and their suitability for everyday wear. The scale assigns a value from 1 to 10, with 10 being the hardest, which can help inform your decision-making process when selecting a gemstone for a piece of jewellery.

Some examples of medium to soft stones are:

1. Amber (2-2.5)
2. Pearl (2.5-4.5)
3. Coral (3-4)
4. Calcite (3)
5. Rhodochrosite (3.5-4)
6. Malachite (3.5-4)
7. Fluorite (4)
8. Variscite (4-5)
9. Lapis Lazuli (5-5.5)
10. Apatite (5)
11. Sodalite (5.5-6)
12. Turquoise (5-6)
13. Chrysocolla (2-7) *Note: Chrysocolla has a wide range of hardness depending on its purity and formation.
14. Opal (5.5-6.5)
15. Amazonite (6-6.5)
16. Moonstone (6-6.5)
17. Sunstone (6-6.5)
18. Labradorite (6-6.5)
19. Chrysoprase (6-7)
20. Tanzanite (6-7)
21. Peridot (6.5-7)
22. Garnet (6.5-7.5, depending on the type)

Please note that the hardness of some gemstones may vary slightly depending on the specific variety. It’s essential to handle these medium to soft gemstones gently and follow proper cleaning, storage, and maintenance practices to ensure their lasting beauty.

Caring for medium to soft gemstones requires a bit more attention to ensure their lasting beauty. Here are some tips to care for these more delicate stones:

  1. Cleaning: Gently clean your gemstones using a soft, lint-free cloth or a soft-bristled brush with warm, soapy water. Avoid harsh chemicals, ultrasonic cleaners, or steam cleaners, as they may cause damage to the stones. Rinse the gemstones thoroughly and pat them dry with a soft cloth.
  2. Storage: Store your medium to soft gemstones separately in a soft pouch or a lined jewellery box to prevent scratches and damage from other pieces. Avoid storing them in direct sunlight, as this may cause fading or discolouration.
  3. Wear with care: Be mindful when wearing your gemstone jewellery. Avoid wearing it during activities that may cause damage, such as sports, gardening, or cleaning. Also, be cautious when applying cosmetics, perfumes, and hair products, as they may cause discolouration or damage to the gemstones.
  4. Avoid sudden temperature changes: Sudden temperature changes can cause some gemstones to crack or fracture. Try to keep your gemstones away from extreme heat or cold, and avoid wearing them while swimming, showering, or using a sauna.
  5. Periodic inspection: Regularly inspect your medium to soft gemstones for any signs of damage, loose settings, or worn prongs. If you notice any issues, visit a professional jeweller for repair and maintenance.

By following these guidelines, you can ensure that your medium to soft gemstones remain beautiful and well-cared for throughout their lifetime.

Please be extra careful with your opals and pearls as they are the stones that are most commonly damaged.


Opals require special care due to their delicate nature. They rank 5.5-6.5 on the Mohs hardness scale, making them more vulnerable to damage from climate, temperature, and humidity changes. Protect your opals by:

  1. Avoiding exposure to extreme sunlight or heat.
  2. Not wearing them in showers, baths, or pools.
  3. Removing them before any strenuous physical activity.

To clean opals, gently wipe them with a damp cloth and a tiny amount of mild detergent.


Pearls, like opals, are delicate and require special care. Since they are often set using glue, they are vulnerable to water and chemicals found in makeup, perfume, and hair dye. To care for your pearls:

  1. Put them on after you have finished dressing.
  2. Avoid wearing them in the shower, swimming pool, or during physical activities.

Clean pearls by gently wiping them with a damp cloth and a small amount of mild soap, like Ivory.

By following these tips from our jewellery care guide, you can ensure that your precious pieces will maintain their beauty and shine for years to come. Remember, proper jewellery cleaning, storage, and maintenance are essential to preserving the lustre and brilliance of your treasures.
