General

Where is your company located?

AMBECA design and manufacturing are headquartered in Hong Kong.

Do you have any retail locations?

Yes! We have pop-up stores in Hong Kong, where you can discover our jewellery in person. Contact us for the latest locations and opening dates.

Orders & Payment

How do I make changes after my order has been placed?

Contact us as soon as possible through our Contact page. We will try to help, but changes cannot be guaranteed once an order has entered processing or shipment.

How do I change the currency?

Use the country and currency selector in the website header or footer. The currency available at checkout depends on your selected market.

Which payment methods do you accept?

Available payment methods are displayed at checkout and may vary by country.

How do you secure my payment information?

Payments are processed through Shopify's secure checkout and supported payment providers. AMBECA does not store your full card details.

Is my personal information kept private?

We use personal information only as described in our Privacy Policy and as needed to process orders, provide support and operate the store.

Jewelry

Are the stones real diamonds?

Our diamond-like stones are cubic zirconia, a lab-created alternative chosen for its clear sparkle and brilliance, rather than natural diamonds. Other gemstones and pearls are identified in the product description. Learn about the stones we use.

Will this jewelry turn my skin green?

Not with normal wear while the protective plating is intact. Our PVD finish helps keep the brass base from contacting your skin. Follow our care guide to protect the finish.

For the plated jewelry, I worry the color will fade off naturally.

Our 18K gold PVD finish is made for lasting shine. Proper care helps preserve its colour: avoid harsh chemicals and abrasive surfaces, and store each piece separately. If you notice a problem, contact our team so we can review it under our one-year warranty. See our Jewellery Care Guide.
