If I buy products from S.Diamond, can I return them or exchange them?

Do you have a custom made product service? And how many days does it take?

Customers can order specific designs by bringing the desired design to the shop or have the shop provide free design services without any charges. The minimum production time for rush orders is seven days. The normal production time is one month, depending on whether the design is a ring, necklace, or earrings.

When should I plate my diamond or gold ring if it becomes dull?

When a diamond or gold ring is worn, the rhodium coating will come off with use, causing the white gold part of the ring to have a yellowish color. The shop recommends using it until the part that is a pandanus that holds the diamond in front has a soft yellow color. The shop recommends that after using it for about 3 to 5 years, it should be used frequently because in the process of preparing the surface for plating, the rhodium coating of the piece must be completely polished off, which will result in a loss of gold weight, so it should not be done often.

What are the steps for cleaning jewelry?

For diamond or gold jewelry, the cleaning method is as follows:

-First, prepare a cup with warm water and add 5-10 drops of dishwashing liquid. Mix thoroughly.

- Use a soft toothbrush to brush the front of the diamond and the bottom of the diamond, then rinse with water again. If it is still not clean, you can repeat until all the stains are gone.

– As for how to dry a diamond ring, use a soft cotton cloth to absorb the water and then use a hair dryer to dry it so that the diamond is as shiny as before.

For products that are gemstone jewelry

Additional precautions include cleaning with a non-corrosive solution and avoiding ultrasonic cleaning because the vibrations can scratch the soft gemstones, or avoiding boiling to clean them with heat.

For products that are pearl jewelry

Since pearls are organic products, regular wear allows the oils from the user's skin to lubricate, making the pearls shinier. When finished using, wipe with a soft cloth. Pearl necklaces should not be soaked in water because the inside is strung with silk which may absorb water. Avoid touching pearl jewelry with hairspray and perfume spray.
Or you can bring your jewelry to S.Diamond for free spa and cleaning services. The spa and cleaning period is 15 minutes.

Do all S.Diamond products come with a certificate?

For round diamonds, there will be a GIA certificate from 0.18 carats and up. For fancy cut diamonds, there will be a GIA certificate from 0.30 carats and up. For products with diamonds per piece less than 0.18 carats and up, there will be a certificate from the shop.
Every product comes with an S.Diamond warranty.

Can I change the size? How many days does it take?

If it is a product from the store, it can be made and put in within two to three hours.
If it is a used product, it will take 10 days because it has to be sent to the factory to check the density of the diamond and re-polished.

Are the online promotion prices the same as in-store?

The price of promotional products online and at the store will be the same and all S. Diamond branches will have the same standard price.
