Care & Handling Information

This page provides helpful information and advice on how to handle your jewelry to maintain its beauty and shine for many years.

Handling Your Jewelry

Your NIWAKA jewelry has been delicately crafted so you can enjoy it for years to come. Please handle it with care and avoid the following in order to prevent damage to the jewelry: dropping, hitting, tugging or applying excessive force of any kind. Chains, in particular, may break or damage your skin if pulled too hard.
We also strongly recommend that you avoid wearing your jewelry while sleeping, exercising or in extreme heat or cold conditions. Severe temperatures may damage the jewelry or cause skin injury due to burning or freezing.
In addition, jewelry and some colored gems may be damaged or discolored as a result of exposure to cosmetics, perfumes, topical medications, detergents, insecticides or hot springs.
Some people may be sensitive to wearing jewelry. If you experience unusual itching or rashes, remove the jewelry immediately.

Gemstone Care

Each type of gemstone has its own unique properties. To preserve the beauty of your gemstones, please use appropriate care and cleaning methods.

- Diamonds

Diamonds are hard gemstones and rarely sustain scratches. However, they are susceptible to cracks (cleavage) depending on the direction of impact applied to the diamond. Therefore, be careful to avoid impacts of any kind – in particular, strong, instantaneous impacts. Although a diamond’s brilliant shine is its greatest feature, sweat and body oils can reduce the shine of your diamond. Wipe the diamond carefully with a soft, dry cloth or use lukewarm water to clean it.

- Colored Gemstones

Depending on the design, your NIWAKA jewelry may include colored gemstones. How to properly care for your colored gemstones may depend on the type of stone. For details regarding specific gemstones, please feel free to send us a message via the Contact Us page.


Cultured pearls are characterized by a beautiful luster and natural hue. However, they are organic and can be damaged by acid, heat, moisture and other such agents. As such, pearls may be subject to color change as a result of exposure to cosmetics, hair products or other similar substances. Make sure to put on your pearl jewelry only after applying makeup. Do not let your jewelry come in contact with substances such as fruit juice and other beverages, detergents or hot spring water. Pearls may also lose their luster if exposed to sweat or body oils. Therefore, after wearing your pearl jewelry, please be sure to clean it using a soft cloth.

Silver Products

Silver has a tendency to tarnish as it reacts with sulfur in the air, sweat or chemicals such as perm solutions. To prevent discoloration, all NIWAKA silver products are coated with rhodium.

Coated Jewelry

Some NIWAKA jewelry is coated with materials such as white or black rhodium. The coating may wear away or peel off over time as you use the jewelry. Polishing with abrasive cloths or liquid cleaners may also cause the coating to wear off. If you wish to have the coating reapplied, please message us via the Contact Us page.

Safely Storing Your NIWAKA Jewelry

Avoid storing the jewelry in direct sunlight, in places with high temperature and humidity, in places with severe temperature and humidity changes or near highly volatile insect repellents. To avoid damage resulting from jewelry pieces coming into contact with each other, please store your NIWAKA jewelry separately. When not being worn, we recommend storing your NIWAKA jewelry in the case it came in at purchase, in a soft bag or in a jewelry box. Please also be careful to store your jewelry in a location inaccessible to small children.

Restringing a Pearl Necklace

When storing a NIWAKA pearl necklace, place it in the case it came in, making sure to lay the necklace flat to prevent stretching or weakening the thread. Please also ensure that the necklace is regularly maintained to preserve its beauty and longevity. We recommend having your pearl necklace restrung if the thread becomes visible when the necklace is held up by one side of the clasp. Should you wish to have the condition of your necklace carefully checked, please make an inquiry using the Contact Us page.

Care & Handling of Jewelry Parts

Earring Backings

For NIWAKA earrings, the type of backing differs by the design of the earring.

- Locking Disk Backing

The locking disk backing can be set and removed by pushing on the catches on each side and sliding the backing. The backing should be set at the indentation at the tip of the earring post to lock in place. Please be careful to avoid forcefully moving the backing without pressing the catches, as this may cause damage. *This is also applicable to the pin brooch backing.

- Silicone-Covered Backing

The entire backing is covered with silicone. Please do not remove the silicone. As a relatively soft substance, it is subject to wear, deterioration and deformation. If you would like to have the silicone replaced, please message us using the Contact Us page.

- Butterfly Backing

Please note that trying to move the backing too forcibly may cause deformation. If you wish to have the backing replaced, please send us a message via the Contact Us page.

Earring Clip (for clip-on earrings; silicone pad included)

If the earring clip feels loose, please put the silicone pad into the hole in the clip to adjust the fit.
